This is a walkthrough for the DS game called "Zero Escape:
9 Hours, 9 Persons, 9 Doors". The original title for the
game was "999: 9 Hours, 9 Persons, 9 Doors"; the name was
changed when the sequel to this game was produced. This is
an M-rated DS game, in which nine people attempt to escape
from a death-ship filled with puzzles.

Would you like to see the puzzles in this game get solved,
as opposed to reading about them get solved? You're in
luck; I have a video walkthrough for the game right here:
This comes complete with commentary from me and my friends,
Paul and Nikola.
003-Endings and Pathways
This game is open-ended, in that it has a number of
different pathways. To explain it simply, there are three
main junctures in this game.
At the first juncture, you have to choose to go through
Door 4 or Door 5. At the next juncture, you pick among
Doors 3, 7 and 8. At the final juncture, you pick among
Doors 1, 2 and 6. If you pick Door 3 second, you
automatically get sent to Door 2 at the third juncture.
This results in 14 different pathways in total. There are
six different endings in total. Three of them can be
considered "bad" endings. Here are the routes which lead to
This ending is triggered by going through Door 2 last.
Doors 4, 3, 2
Doors 4, 7, 2
Doors 4, 8, 2
Doors 5, 3, 2
Doors 5, 7, 2
Doors 5, 8, 2
This ending is triggered by going through Door 1 last.
Doors 4, 7, 1
Doors 4, 8, 1
Doors 5, 7, 1
Doors 5, 8, 1
Going through Doors 4, 7 and 1 can also result in the true
ending or the coffin ending (see below).
This ending is triggered by going through Door 6 last.
Doors 4, 7, 6
Doors 4, 8, 6
Doors 5, 7, 6
This ending (in which Junpei opens a locked safe, among
other things) occurs if you go through Doors 5, 8 and 6.
Coffin and True Endings
The Coffin Ending and the True Ending can both occur, if
you go through Doors 4, 7 and 1. The two endings are
identical, except the coffin ending stops abruptly once the
characters reach the coffin. The true ending continues for
a few hours past the coffin scene.
Don't bother trying to get the Coffin Ending. Try to get
the True Ending; this automatically unlocks the Coffin
In order to get the True Ending, you must go through Doors
4, 7 and 1. You must also do five additional things:
1. Get the bookmark from Santa in Door 4.
2. Talk about Ice-9 in the kitchen (Door 4).
3. Talk about Ice-9 in Door 7.
4. Give the bookmark to Clover in Door 1.
5. See the safe ending.
If you do the first four things, but not the fifth, you get
the coffin ending. If you fail in any of the first four
things, you get the axe ending.
004a-Start of Game
The game begins with our hero, Junpei, waking up in a room
on a sinking ship. He needs to escape from the room he's
in, because the room is slowly filling with water!
To get out of the room, you need to get the six cards from
the two locked suitcases.
A blue key is inside the kettle, by a corner of the room. A
red key is taped to the mirror, which is left of the exit
door. Simply tap on the mirror to move aside the curtain,
then tap on the key.
Technically, you can unlock each briefcase with just the
keys. But let's be thorough and get the briefcase codes
There is a piece of paper, under the pillow of the bottom
bunk, of the bunkcase near the door. There is another piece
of paper on the bulletin board, which is above the sink.
Also above the sink is a framed picture. There is a
screwdriver on the chair, hidden inside the stove. Open the
stove and tap the chair to get the screwdriver. Combine the
screwdriver with the picture from for an old photo.
If you examine the photo, you'll notice there are symbols
on the back. Each symbol stands for a certain number. The
symbols match perfectly with the symbols on the two pieces
of paper you have.
Putting the clues together, and following the arrows on the
pieces of paper, you can deduce that red is 7485, and blue
Go to the blue briefcase, on the lowest bunk of the
bunkcase farther from the door. Use the blue key on the
keyhole, and turn the dials so the number is 0263. Tap on
the key to unlock the briefcase. Tap on the briefcase to
open it. Inside, you find a file and three cards.
Go to the red briefcase, behind the curtain in the corner
of the room where the stove and kettle are. Use the red key
on the keyhole, and turn the dials so the number is 7485.
Tap on the key to unlock the briefcase. Tap on the
briefcase to open it. Inside, you find three cards.
Now that you have all the cards from the briefcases, go to
the exit door. See the card scanner next to the door? Use
the red cards and the blue cards on the card scanner.
You get a chance to work with digital roots, which the file
in the blue briefcase discussed. The digital root of a
number is the sum of its digits. Should you have a sum
which is greater than 9, add its digits again.
Junpei needs to get a digital root of 5, which is the
number on the door and his wristwatch. The answer is 6, 7
and 1, because 6 + 7 + 1 = 15, which has a digital root of
Tap those three cards, then pull the lever. Now tap on the
door to leave. Junpei escapes from the room and meets with
the other eight participants in the Nonary game.
Eventually, the characters decide to split up into two
groups. One group goes through Door 4, the other group goes
through Door 5. Junpei is fortunate enough to pick which
door he wants to go through.
Santa, Lotus and June go through Door 4 with Junpei. They
end up in the Second Class Cabin. The major plot points in
this area are All-Ice, the clover bookmark, telepathy and
This area is split up into two rooms. June and Junpei are
in one, while Santa and Lotus are in the other. This room
has a living room, a bedroom, and a small hall leading to a
Check the table in the middle of the living room for
matches. When you do this, June and Junpei wonder why
they're both here together, after not having seen each
other for so long. They also get a bit flirty with each
Enter the bedroom. Open the dresser drawer for a key and
take the map from the wall above the bed. June and Junpei
will then have a conversation about the Titanic and the
Egyptian princess whose body was frozen and never melted.
That's it for this area. Leave the bedroom through the
door, then go through the door to the left of the small
hallway, and Junpei goes to Lotus' room, which is a mirror
image of the rooms you were just in.
On the table in this living room, there is a candle. Take
the candle and combine it with the matches to light it. Go
into the bedroom area, and Junpei uses the candle to light
things up so he can see.
Use the dresser key on the dresser here to get a plate.
Examine the bed and take the curtain which is on top of it.
Back away from the bed, and the candle burns out. Pick up
the candlestick holder.
Go back to the living room area, and use the candlestick
holder as a key on the display case. Take the black-and-
Santa will start a conversation with Junpei, and he tries
to give Junpei a clover bookmark. Take the bookmark away
from Santa. If you do not, you will be unable to get the
true ending of the game.
Go down the small hallway and into the bathroom. When
you're facing the exit door, you can see the shower curtain
rod on the ceiling. Use the shower curtain on it. Turn
around so you're facing the shower wall, then pull the
Look in the hole. It shows the tile which is fifth from the
top and third from the right.
Leave the bathroom and go back to the room with June. Go
into the bathroom here and tap the tile which is fifth from
the top and third from the right. Junpei pulls it out.
Leave the bathroom. Look at the picture hanging at the end
of the hallway here. Now, go to the room with Lotus and
Santa. Use the three tiles on the picture in their hallway.
Swap and rotate the tiles so they match the picture in
When you finish the puzzle, the picture lowers and you get
a Mars key. A conversation with Lotus ensues. She talks
about Sheldrake's theories on telepathy, which involve
sending messages through something called a "morphogenetic
When she's finished talking, leave this room. Use the key
on the double doors to unlock them. Our heroes will go
through the doors and end up in the kitchen.
You start up near a bunch of plates. The voucher left of
the plates describes them. It seems that the person who
runs this kitchen uses hexadecimal, a base-16 system in
which the letters A through F represent the numbers 10
Go right, to where you're face two doors. Enter the right
door. Examine the cheese shelf, and tap on the middle
cheese. Behind it is a bottle of oil, which you should pick
Move aside the white curtain on the shelves to the left,
and there is a wooden box on the middle shelf. Open it to
get a dull knife. June will talk for a bit about the
Titanic at this point.
Leave the room. Now try to go through the door on the left.
This is the freezer, which is bolted shut. Use the bottle
of oil on the bolt to loosen it.
Santa, Junpei and June all enter the freezer and get locked
inside. Oh no! Examine the shelves here for a chunk of
pork. Open the cabinet here. Take frozen chicken from the
bottom shelf and take dry ice from the top shelf.
Santa and June start a conversation about dry ice and Ice-
9. Choose "it did strike Junpei as rather odd" to continue
the conversation. You must do this, if you want to get the
true ending. You also must choose "was honestly impressed".
Examine the trap door on the floor. Open it to get a rope
and a water bottle. Combine the dry ice with the chicken,
and Junpei smashes the ice into tiny pieces. Combine the
dry ice with the water bottle, and Junpei puts the pieces
in the bottle.
Combine the water bottle with the rope to make a water
bottle bomb. Turn towards the door and examine the
doorknob. Junpei lets warm water go into the water bottle
filled with dry ice, and he ties it to the door.
The three people hide in the trap door area, while Junpei
throws a piece of dry ice at the makeshift bomb. It
explodes, destroying the ice barrier on the lock. This
allows Santa, June and Junpei to exit the freezer.
There's not much left to do in the kitchen. Turn until you
see the sink. Zoom in on it, and take the whetstone left of
the sink. Combine that with the dull knife to get a sharp
Turn to the grill, which is left of the plates and right of
the sink. It's on the right-hand side of the screen. Use
the pork (from the shelves in the freezer) on the grill to
warm it up. Use the sharp knife on the pork to get the
piece of paper.
The paper reads "C + 10 + F". We know that whoever runs the
kitchen uses hexadecimal, and in hexadecimal, that equation
equals 43. Back away from the grill and zoom in the coded
lock under a stovetop. Enter 43 to open the lock. Now open
the doors to get the Saturn key card.
Use the Saturn card on the key card reader by the exit door
to unlock it. Now you can use the door to exit the room.
Seven and Snake go through Door 5 with Junpei. They end up
in the First Class Cabin. The major plot point in this area
is the locked safe.
The exit door is locked, with a musical code. Play the
correct notes on the piano, and the door will unlock. Of
course, we need the proper musical score first.
Look under the pillow of the canopy bed to find the A Score
Plate. After this, Snake talks about his blindness for a
There are two doors that are side-by-side in this room.
Open the right door. There is a locked safe in here, which
will become important in the safe ending. For now, our
heroes can't open it. Instead, open the cabinet below the
safe for the C Score Plate.
Now go through the left door, to reach the hallway. Again,
you have two doors onscreen. The left one leads to the
bathroom, while the right one leads to a sitting room. Go
into the sitting room.
There is a fireplace in this room, with a musical score
above it. You can't reach the score, due to the fire.
Turn towards the two side-by-side doors. Grab the vase
which is left of them. Then, open the left door and open
the cabinet inside for the G Score Plate.
Go through the right door to reach the hallway. From this
angle, you have three doors. The left one takes you to the
room with the piano, the middle one takes you to a
bathroom, and the right one takes you to a toilet.
Go to the bathroom (the middle door). Use the vase on the
bathtub to fill it with water. Then, pull the plug (on the
left) to drain the tub. This gets you the D Score Plate.
Back out of the bathroom to reach the sitting room. Use the
vase of water on the fireplace to put out the fire. Pick up
the score plate here, which is the only score plate to not
have any notes on it. It is also the only score plate which
isn't transparent. Picking up this plate will start a
conversation with Seven, about his amnesia.
Those are all the score plates you need! Go through the
right door (of the set of two doors), then the left door to
reach the piano room. Take the map off of the piano, then
use the scores on the music stand.
Now you have to play a short song on the piano (the
Westminster Quarters). The keys of the piano are all mixed
up; for example, pressing A will get you a C, pressing E
will get you an F, and so on.
You want to figure out which notes go with which keys. The
solution is this:
3, 4, 5, 6
3, 5, 4, 3
4, 3, 5, 6
6, 5, 4, 3
It's not TOO difficult of a puzzle, given that you only
have to use four keys. Playing the song unlocks the exit
door. Go through it. Snake, Seven and Junpei will travel
through the ship, but they find that everywhere is locked,
except for the casino.
In this room, you need to get nine playing cards, and you
can play baccarat.
You can get four cards, right off the bat. The 4 card is
under the glasses (on the wall of the bar). The 5 card is
on a square table. The 6 card is on the mantle of the
fireplace. The 7 card is on the bar counter.
Go to the fireplace. You have two lights on the mantle.
Turn them on to see club, diamond and heart. Turning on the
lights makes a bag of coins appear in the fireplace below.
Go to the slot machines. The ones on the right and left
don't work, so use the middle one. Put a coin in the slot,
then select "spin roulette". Press the buttons from the
fireplace lights: club, diamond and heart.
Junpei gets 777 on the slot machine. The bottom drawer of
the machine unlocks. Open it and take the 2 card. The Venus
key is also in this drawer; our heroes will use that to
unlock the gate in front of the stairs.
Go to the baccarat table in the corner, which is red. Pick
up the 3 card. You should now have cards 2-7.
Tap on the glass plate in the middle of the baccarat table.
It's the 8 card, and you have to play baccarat to get it.
Seven will explain the rules of baccarat, in case you
haven't played it before. He says that you play, by using
the digital root of the cards in your hand. A digital root
of 9 is the highest score.
Well, we're playing against 8, so we have to get a 9 to
beat it. To have a digital root of 9, play the 2, 3 and 4
cards. Tap on an outline, then tap on a card to put it in
the outline. You win, and your reward is the 8 card.
Go towards the exit door (past the slot machines). On the
wall, you have a 9 lock, with the ace card on it. If the
ace card is considered to be one, we can add the eight card
to it, in order to get nine.
Put the eight card into the spot which says "LOCK" to open
it. Another lock appears. Put your three cards into the
three slots. The exit door to this room will open, allowing
you to leave.
Junpei tricks Seven, June and Santa into going through Door
3 with him. This room is the shower room, and a nasty
surprise awaits our heroes inside.
Turn towards the row of toilets. On the shelf in the
upper/left, you find toilet paper with red marks, along
with a bottle of luminol. Examine the left stall to get a
bucket and a broom. This causes June to talk to Junpei
about the rabbits they took care of in 6th grade.
The middle stall has a screwdriver hidden inside the water
tank, as well as a stain inside the toilet bowl. The
rightmost stall has a red key card inside the water tank.
Turn right. There's a thermometer on the wall. Use the
screwdriver to get the thermometer. It says "open" at the
bottom, indicating that if it gets past a certain
temperature, something opens. Turn to the showers and use
the thermometer on them. This opens the thermometer,
getting you a piece of paper. It reads "957+".
Under the showers is a small area with pipes. You want to
arrange them in a certain order. Turn to the wall with LLR
written on it, and spray luminol on the wall. Press the
light switch on the wall, and the luminol lights up three
The wall reads LLRLRL. Turn the lights on, and open up the
pipe box under the showers. Tap the valves so that, from
left to right, they are LLRLRL (or left, left, right, left,
right, left). Turn left and examine the drain on the floor.
It's now full of water. Take the lid off of the drain and
pick up the Mercury key card.
Use the empty bucket on the showers here to fill it with
hot water. Go back to the toilets and go to the middle
stall. Use the hot water on the water tank, then tap on the
tank and you flush the toilet. This gets rid of the stain
in the toilet bowl giving you the clue "185+".
You have one more clue to get. Combine the broom with the
toilet paper to get "634+". Put the clues together, and you
get "634+957+185=". They equal 1776.
Go to the exit door. Slide the red card through the reader,
then swipe the blue card. Enter 1776 and press "E". The
door opens, and you get to leave.
The Mercury Card you found in this room leads to a Number 2
door. Junpei, Lotus and Seven automatically go through it.
Clover and Seven go through Door 7 with Junpei. They end up
in the operating room. The major plot points in this area
are Seven talking about All-Ice, and the clover bookmark
There are two operating tables here, with large mannequins.
One is female and the other is male. Go to the female
mannequin, who is under a white cloth. Most of her body
parts aren't here.
Near the female mannequin is a table with forceps. Take the
Turn right. Pick up the chest from the table. Turn right
twice, to where a medical mannequin stands. Use the forceps
on the mannequin to get a lung. Pick up a scalpel from the
table here and combine it with the lung to get a key.
That's it for this area behind the wooden partition. Go to
the other side of the partition, heading right. You see two
doors. The right door leads to the 7 door, and the door on
the left leads to a chemical room.
Use the organ key on the door to enter the chemical room.
Zoom in on the table and take the note. It says iron is 1,
salt is 2, water is 3. It asks what carbon dioxide, ammonia
and ethanol are.
If you look at the various things in the room, it gives you
the chemical formulas for those various compounds. You'll
notice that iron is made up of one atom, salt is made up of
two, and water is made up of three. Carbon dioxide is made
of three atoms, ammonia is made of four, and ethanol is
made of nine.
Insert 349 as the combination to the locked safe. Inside is
an arm and a heart. Take the blue and red liquid on this
table, then leave the room.
Seven will start talking about EDT. In order to get the
true ending, you need to mention Ice-9 to him. This makes
him talk about All-Ice, the Egyptian Princess that June
mentioned in Room 4. If you're not on the path to the true
ending, only part of the conversation with Seven occurs.
Go to the left side of the partition. Open the door here
with the organ key, and head into the room. Open the drawer
of the large dresser to get notes. They say how much John
and Lucy's various body parts weigh.
Check the table near the exit door. Turn on the light to
the left. The light shines on the three lockers, which are
red, blue and purple.
Pour red liquid into the beaker, to shine a red light. Back
away, then pout blue liquid into the beaker, to shine a
blue light. Pour both red and blue liquid into the beaker
to shine a purple light.
Your actions unlock the red, blue and purple lockers. The
red and blue lockers both have a leg inside. The purple
locker has a stomach inside. Pick up those body parts.
Go back to the area with the mannequins, by pressing the
down button many times. Take the cloth off the female
mannequin and use the body parts on her to rebuild her
Examine the mannequin's body again. You get a puzzle, in
which you want to swap body parts, to get the two
mannequins to weigh the correct weight. According to the
medical files, the male mannequin weighs 51.3, and the
female mannequin weighs 53.2. To get this weight, swap all
the body parts except for the hearts.
This unlocks the box at the base of the male mannequin. Go
there and open it to get the Jupiter key. Pick it up.
Head to the room with the lockers. Use the Jupiter key on
the door to unlock it. Before our heroes leave, a
conversation ensues as Junpei goes back for Clover and
talks to her. She talks about the concept of identity,
bringing up things such as Locke's socks and the Ship of
To get the true ending, you must give Clover the clover
bookmark (obtained from Santa from Door 4). This cheers her
up, and Clover starts to trust Junpei.
Door 8 leads to the laboratory. Junpei, Clover and Lotus go
into this room. The major plot point in this room is
learning about prosopagnosia and Snake's arm.
Clover is quickly trapped in another part of the lab.
There's a mannequin and some equipment there. In the part
Junpei can access, there are lockers, a computer, and
Look at the machines. There is a small tower of equipment
on the right, with a power cable on top. Take the power
cable. Now go to the computer, and use the power cable on
Alas, you need a three prong to two prong adapter! Look at
Clover's area, through the big window. Tap on the machine
by the mannequin's head, and she'll get the adapter you
need. Go to the bars and tap on them to get the adapter.
Combine the adapter with the power cable, then use it on
the computer monitor. A long scene then plays, in which
Lotus talks about prosopagnosia and human brains.
A puzzle will appear on the screen. You want to turn all
the panels green, but you can only touch four panels
without having the puzzle automatically reset. Pressing a
panel changes the various panels adjacent to it.
Press the panels in this order:
The solution to this puzzle can be found in Clover's area,
under some permanent marker on the table next to the
mannequin. But it's not too difficult to figure out the
Solving the puzzle unlocks the lockers. Go to them and
examine the nine lockers on the right. Inside the middle
locker is the activation key, along with the Earth key.
Pick up the key, and Clover talks with Junpei about her
brother, Snake. Snake was in a car accident, in which he
lost his sight and his left arm.
Go right, to the place with machines. Zoom in on the
computer monitor near the keyboard. Use the activation key
on the keyhole to the left, and the monitor turns on. Read
the monitor to learn that power has been restored to
Look at Clover's area, through the window. Tap on the
machine in the upper/left, which is connected to the
mannequin through a lot of cables. Tap on the machine
again, and Clover turns it on to full power.
A fire starts. The emergency escape system is activated,
due to the fire. Turn to the exit doors. Open the door on
the right to save Clover, and open the door on the left to
Clover and Ace go through Door 5 with Junpei. They end up
in the chart room. The major plot points in this area focus
on Snake, the Captain, and All-Ice. Another major plot
point (which doesn't get discussed while in the room) is
the fact that Clover finds the combination to the safe in
Door 5 inside this area.
The group splits up. Clover and Junpei take the chart room,
while Ace goes into the wheelhouse. Let's start by doing
everything here in the chart room.
In one corner of the room, you have the map dresser. That's
a wide dresser with big drawers, for storing maps. Open it
up and take a stack of nautical charts.
Turn to the corner of the room with a desk. Examine the
bookshelf above the desk for a Captain's Log. It
corresponds to the map on the wall. Use the stack of
nautical charts on the map on the wall. Junpei takes the
only map which matches the Captain's Log and puts it in the
Open the desk drawer here, and you get a watch. Ace will
come in and look at the watch. Junpei gets rid of Ace, so
Junpei and Clover can talk in private.
Clover won't talk, unless you've gained her trust in Door 7
by giving her the clover bookmark from Door 4. In other
words, you need to be on the path to the true ending, in
order for her to talk.
Clover talks about the death of her brother. She does the
math to determine who the killers must be. Snake's bracelet
is , and if his bracelet was used to get him inside the
3 door, the killers' bracelets must have a digital root of
1. The only pair Junpei can think of which fits that
requirement is Seven and Santa.
There are other possibilities of course. But just when
Clover is about to explain the most likely motive for
killing her brother, Ace returns. He and Junpei go out to
Let's solve puzzles here now. There are two steering wheels
here. One faces windows, while the other faces a wall. Turn
towards the wall-facing steering wheel.
Tap on the engine order telegraph and the compass (the two
devices near the steering wheel), and Junpei will be able
to move the steering wheel. You want to steer the ship in
the directions indicated in the Captain's Log: South, West,
Southwest, Northwest, East, and North.
The handle comes off of the steering wheel. Go to the
engine order telegraph and use the handle on that. You want
to move the ship in the speeds indicated by the nautical
chart: Full, Half, Slow, Full, Half, Dead Slow, and Stop.
Turn to face the doors. Junpei just lit up the display
board. Tap on it and Junpei reads that the only port
connected to a time is the last one, at ten seconds past
Examine the exit door, which has a watch-shaped
indentation. Use the watch on the display board to set it
to the proper time, then use the watch on the door to
Our heroes go into the next room, which is the...
The first room here has electronic equipment. The second
room has a corpse, dressed up like a boat captain. Could he
be the real Zero? Junpei doesn't seem to think so.
Clover and Junpei get to examine the room with the corpse.
Start by going to the bed. Next to it is a small dresser,
with a music box on top.
Turn to examine the TV monitors. Press the buttons on the
control panel before the TVs. The word "Zero" appears, as
well as the exit door.
Open the desk drawer and pick up the numerical chart. It
gets added to the files. The chart shows off hexadecimal
Back away from this area. Clover and Junpei will talk about
the dead man. If you're on the way to the true ending,
Junpei will describe Snake's corpse to Clover, in gruesome
detail. Clover, who knows about Snake's left arm, comes to
a realization when Junpei mentions that it was blown in
Clover talks about nine years ago, when there was a
telepathy experiment on this ship. She wasn't here, though;
she was in Nevada. Before she can explain too much, Ace
interrupts and takes Junpei to the other room.
Check out the desk in front of you. There is ink inside a
drawer and screwdrivers on top. Turn left and open the
other desk drawers in this room. They have paper.
Combination time! Combine the music box with the
screwdrivers to get a cylinder. Combine the cylinder with
the ink, then combine the cylinder with paper. You end up
with a Morse code chart.
Go to the telegraph machine (on the right side of the
equipment). Enter in the Morse code. To make a dot, tap the
lever. To make a dash, hold down the lever. Copy the code
on the top screen.
This unlocks the drawer below. Open it to get a book about
All-Ice, the Egyptian Princess. The drawer also has a
keycard to the library (past the 9 door). Ace and Junpei
will talk about All-Ice. Ace believes it is possible she
was cryogenically frozen. If she ever goes somewhere with a
temperature higher than 96 degrees, the Ice-9 keeping her
frozen will melt, and she will once more come back to life.
This is all hypothetical, of course. There's no solid proof
that All-Ice is aboard the ship, right? And our heroes
aren't close to a desert or any other place with a
temperature over 96 degrees, right?
Once the conversation is over, pick up the unique key that
is inside the drawer. Go to the room with Clover and zoom
in on the exit door. There is a keyhole on the panel here.
Use the key on the keyhole to light up the panel.
According to the TV monitors in this room, the password is
"Zero". According to the hexadecimal file found below the
monitors, this equals 35, 14, 27 and 24. Enter those
numbers and press "E". The door unlocks and you can leave.
As Junpei and Ace leave, Clover stays behind. If you are
going to the true ending, she picks up the watch belonging
to the Captain. If you are going to the hatchet ending, she
picks up the hatchet. In both endings (and in the safe
ending), she also picks up the note which is the clue to
the combination for the safe in Room 5.
Lotus and Seven go through Door 2 with Junpei. They end up
in the confinement room. Once you get through this area,
you will have the submarine ending. The major plot points
in this area about Lotus' daughters and Seven rescuing
kidnapped children nine years ago.
There are three doors here. Let's tackle them from left to
Go through the left door. The sink here has a tile stuck in
it. The drawing on the sink's mirror is a water design, so
presumably we have to use water to get the tile out.
Head to the toilet and take the toilet paper off. Tap on
the toilet paper holder to get half of a screwdriver. Pull
the toilet handle to get it, then combine it with the
screwdriver. You get a full screwdriver.
There is a desk in the corner of the room. The drawer is
held in place by screws. The screws are on the top of the
desk. Use the screwdriver on the screws to get the drawer.
Leave this room, then go through the middle door. This room
also has a desk in the corner. Take the drawer out of this
desk, then put the drawer from the left room inside. Then,
open the drawer to get a tile.
Use the screwdriver on the desk drawer in your inventory to
get a faucet knob. Use the knob on the sink here. Junpei
fills it with water. Go back to the left room and check its
sink. It's now filled with water, thanks to Junpei's
actions. Pick up the tile.
Picking up the tile causes some of Seven's memories to
return. He remembers being held hostage in this room. He
managed to save several children who were being used as
part of an experiment on this ship.
Leave this room. Go through the rightmost room, which is
mostly dark. Use the drawer (which has a mirror on the
back) on the beam of light here. Reflect it on the right
mirror to get a moon and sun. Reflect it on the left mirror
to get 4 and 7.
Leave this room. According to what you just saw, 4 is left
of 7. This means you want to flush the toilet in the left
room four times, and you want to flush the toilet in the
middle room seven times. An odd puzzle, to be sure. Do this
to unlock the desk drawer in the right room, which has two
Now that you have all the tiles, go into the main hall. On
the right wall is a door with tiles on top. Use your tiles
on the door tiles. You have four tiles, and the door has
four "E" tiles. Swap the "E" tiles for your tiles to open
Lotus says that this solution worked, because "E" is 14 in
hexadecimal. Junpei isn't interested in why the solution
works. He's more concerned with going through the door and
Well, this certainly is an unpleasant room to be trapped
Examine the torture chair. It has a sun symbol engraved on
the manacles. The glass below the chair has water
underneath it. The green monitor next to the torture chair
has a puzzle on it.
In this puzzle, you want to press the four buttons in the
proper order, so the picture on the bottom screen matches
the picture on the top screen. Press the upper/left,
lower/left, then lower/right buttons and hit check.
The monitor says it needs to prepare, which sounds ominous.
Tap the machine again to learn that the disposal tank needs
water. Go to the machine in the room, which is by the wall
and farther from the chair.
Pull the yellow lever on this machine. Water drains from
the area below the chair, and it lights up. Examine the
floor to see a dead shark, with the letters EDBF written on
it. Ah, so there was a shark tank underneath this chair.
If you check the monitor by the chair, it no longer gives a
water error, because you drained the water. Instead, the
monitor now says that it can't communicate with the chair
because the power is off.
Go to the machine. Press the buttons E, D, B and F. This
turns on power to the chair.
Go back to the monitor. Now that the chair has power, it
says that the manacles on the chair need to be unlocked.
Turn to the corner of the room, where this is a table
covered with tools and a cloth. Take the wrench from this.
Now, examine the pipes underneath the catwalk. The cover to
the tank can be taken off with the wrench.
Remove the tank cover, then tap on it twice. Junpei sticks
his arm inside to get a Sun Key. Use this key to unlock the
manacles on the chair (which have a sun emblem on them).
Go to the monitor. It needs someone to sit in the chair.
Seven can't fit, so Lotus sits in the chair. Before this,
she talks about her twin daughters. It turns out that her
daughter Nona was one of the children that Seven rescued
from this ship, nine years ago.
All the children who were kidnapped showed signs of
telepathic powers, at least with their siblings.
The conversation is cut short, and Lotus sits down.
The puzzle here is to make the bottom screen match the top
screen again. Examine the right side of the head, and turn
both buttons to "1". Switch to the left side of the head
and turn both buttons to "2". Hit check.
This unlocks the exit door. Tap on the door to leave.
You're going to get the submarine ending after this.
Ace, June and Santa go through Door 6 with Junpei. They end
up in the Engine Room. The major plot points in this area
are a lecture about how life-threatening danger is helpful
for telepathy, Santa's sister, a loaded gun and Ace's
You start off on the bottom level of the engine room, but
you need to go up to the top. Turn right and tap the stairs
to go up. Ignore the puzzle on the wall for now, and go
upstairs a second time.
You end up near the A door. Go through it, and you end up
in an area with three doors (A, B and C). Alphabetical
order dictates that B comes after A, so go through the B
Once you go through the B door, turn right. You can't turn
left, due to the boxes on the catwalk. In the corner, there
is a winch. Tap on it, then tap on the wheel. Junpei
accidentally pulls the wheel off.
So much for the B area. Go back through the B door, to
return to the three door area. This time, go through C (on
the right). The C area also has a winch, only this one
lacks a wheel. Use the wheel on the winch, and then turn
the wheel. Junpei lowers the crate to the ground.
Santa will start talking about lab rats. An interesting
experiment showed that lab rats can more easily use
telepathic powers, when faced with a life-or-death
situation. Danger apparently strengthens telepathic
Now that the crate is on the ground, it's time to go to the
ground. Go through the C door, then go through the A door.
Head down the stairs and look at the conveyor belt. The
lowered crate is here. Examine the crate (left of the
conveyor) to get a control panel.
Open up the small door (on the side of the conveyor tunnel)
and put the control panel inside. The conveyor belt starts
up and fills the crate with coal. Pick up the crate.
Give the crate to Santa, so he can deliver it to the bad
boys and girls on Christmas Eve, and...wait, no that's not
what you have to do.
Turn left, and zoom in on the three circles built in on the
furnace. Fill them with coal. Now, go up the stairs, to the
device on the wall. Pull the rightmost switch to ignite the
coal in the furnace. This turns the three large gears by
Examine all three gears. Each one has a disc attached. Go
down the hallway with the gears, and go up the stairs near
the corner. At the top of the stairs is a device for the
The discs are placed, just like how they were in the gears.
That's silver on top, bronze on right and gold on left.
Swap the discs so they are in the right positions, then tap
each disc so the three discs form a large star polygon.
That's it for this room. Everyone leaves, and Santa talks
for a while about his sister, who died nine years ago. Our
heroes then go through the door to the cargo room.
This room has cards for all the contestants in the Nonary
When facing towards the (electrified) fence, you can find
Santa's card in a bag, on crates to the right. You can find
the 9th Man in a bag, on the crates to the left.
There are two bag, near the stairs to this room. They
contain the cards for Snake and Clover. Ace's card is in
the box here. In the corner of the room, there are some
blue boxes. Get the Seven card from the bag here, and look
inside the highest crate, in the corner. It has the Junpei
and June cards.
Examine the blue boxes. The Lotus card is there. use the
cards on the boxes. Junpei is about the put the cards in
the boxes, when June collapses. Santa reveals that Ace is
the President of Cradle Pharmaceutical, which makes the
soporil drug that Ace used on himself in the hospital room.
When Junpei returns to Ace, he finds that Ace was unable to
solve the puzzle. He has vision problems. If you went
through Door 8 before this door, Junpei realizes that Ace
probably has prosopagnosia.
Junpei solves the card puzzle to get numbered pins. Time
for some number puzzles. Go all the way up to the top of
the stairs and use the pins on the machine.
The digital root of the top row and the digital root of the
bottom row both light up. If a number is already lit when
its digital root is entered, it gets turned off. Here's a
set of four things which will light up numbers 1 through 8.
6 = 987
7 = 124
1 = 946
8 = 125
2 = 137
3 = 984
4 = 742
5 = 986
When you turn on all the lights, the shutter to the right
opens to reveal a magic square. That's a square in which
every row, column and diagonal equal the same number. The
number you want is 15 (which is "F" in hexadecimal, hence
the "F" on the top screen).
8 1 6
3 5 7
4 9 2
You've powered on the machine! Look at the top part of the
screen for a pushing puzzle. Tap on the screen and the
control stick to start it.
Go up, right, up, right, right, down, right, down, down,
and down. You're in the lower/right corner. Go left, left,
up, right, down, right and up. You have one block in
Go down, left, left, left, up, left, up, up and right three
times, to get a second block in place. Go down, down, left,
down and right to get a third block in place. Now go up
three times, left twice, down, left, down and right until
the final block is in place.
Now our heroes can climb the boxes to the other side of the
electrical fence. Go downstairs and up the crates to find a
coffin with a gun inside. It also has a key to the exit
Our heroes decide to leave the loaded gun behind. Go up the
stairs and use the key on the door to exit. You are either
going to get the knife ending or the safe ending after
Seven, Snake and Clover go through Door 9 with Junpei. They
end up in the library. The major plot points in this area
all deal with what happened nine years ago.
In the library, you want to find three pop-up books, as
well as three light bulbs. The first light bulb is in the
lower/right section (if you're facing the table). Move the
books around to read "open here, find bulb" to get a bulb.
Turn left. Examine the bottom/left area. In the middle
shelf is a picture book. Examine the upper/left area. In
the lower/right shelf, behind a book, is a light bulb.
Turn left again. You're facing the big metal doors. Examine
the shelves left of the doors. In the middle is another
Turn right. Examine the middle shelf, in the lower/right
section for a pop-up book.
That's it for the upstairs area. You get two bulbs and two
picture books. Go downstairs. Examine the bookshelves
behind the set of stairs (there are two sets, but only one
has books behind it). In the lower/right you find another
In the center of the downstairs part is a circular area. A
set of double-doors is behind it. Examine the set of double
doors. Look at the books through the glass to see that each
book is numbered. Insert the book numbers (632415) on the
lock to open it. Pick up the light bulb in the lower left.
Go to the items screen. Examine all three picture books for
pop-ups. Go to the circle in the middle of the downstairs
area. Put the three pictures books on the stands, and put
the three lightbulbs in the lights. You get the clue
Tap on this clue to start a long conversation with Snake
about what happened nine years ago, and about telepathy in
Turn right, to look at the shelves. In the lower/left, some
shelves are only half-full. The book colors all match in
this area, too. Zoom in on them and tap the fifth Sheldrake
book. This reveals a button.
Press the button, then go upstairs. The metallic door has
retracted. Go to where the door was and check the monitor
in the middle. The Roman numerals above the monitor spell
out "DEAD" (in hexadecimal). Enter that as the password.
The door right of the monitor opens. Go through it to
You should start off as far to the right as possible. Take
the map from the drafting table on the right side of the
Turn left. You have two machines here, one on the left and
one on the right. Go to the right machine for an addition
puzzle. You want to get all of the rows and columns to add
up properly. All the letters stand for hexadecimal numbers.
If you play around with the machine, you'll figure out that
the all squares must be lit, except the upper/left and
bottom/middle squares. To get this to happen, press the
middle square, the upper/left square and the middle/right
square, in any order.
A cross emblem pops out on the right. Pick it up and back
away. If you examine the machine to the left, you'll notice
it needs four emblems before it will work.
Turn left. You have three machines here. The right one is
the four emblem machine; ignore it. Go to the left one.
This is just like the steering puzzle in the wheelhouse
(before the Captain's Quarters). Junpei got the proper map
from the far right side of the room, so he can steer
according to the map. Go south, west, southeast, northeast,
east, north and east. Solving the puzzle gets you the helm
Back up. Examine the middle machine, which is a Morse code
machine. You want to type in "ice", as in "All-Ice". That's
two dots on the first line, dot dash dot dash on the second
line, and a dot on the third line. Solving the puzzle gets
you the code emblem.
Turn all the way left. Open the shutter on the right.
Inside is a coffin. Does it belong to All-Ice? If you've
solved the Morse code puzzle, you can open it and find out.
At the bottom of the coffin is the Neptune key which leads
to the incinerator, and the coffin emblem.
You should have all four emblems now. Go to the four emblem
machine. Snake will tell you the order to put the emblems
in. Start with the helm emblem.
You have a puzzle, in which you divide the people into two
groups, according to their digital roots. Put 345 in 3, and
12678 in 6. Hit check to get the computer to accept it.
Next is the cross emblem. For this puzzle, put 235 in 1 and
4678 in 7. Hit check.
Next is the code emblem, which wants you to divide into two
groups of seven. Put 457 in one and 268 in the other.
Finally, you have the coffin emblem. This is a trick
puzzle. Put all the numbers in 8.
Solving the puzzle unlocks the desk drawer. Open it and
take out the picture. It is of the four people who set up
the Nonary Game, nine years ago. Seeing this picture causes
Seven to regain his memory. He tells a story, which is
longer than the version of the same story that he tells in
After the story is done, you get a keycard. Use it on the
reader by the exit door (all the way to the left). Go
through the door, and our heroes go to the incinerator.
After a long, long time, you will reach the final puzzle.
It's Sudoku, and since you're seeing it from another
person's perspective, it's upside down. Simply turn your DS
upside down and enter the numbers.
