I really don't get this at all. In Dr.Kirk's secret lab Rick tells you to put in three sets of codes to open the evacuation hatch. I put in the first and second codes for the hatch. but on the third one it gives you like 5 sets of letters.

ex:

DEF CBD DEA FBC CBD
ABC FAE BFC DAE AED


This does not make sense because the code can contain at most only 10 letters. Why are you given so many letters for a 5-10 digit code? Which letters do you use for the code?

every time 3 of the letters spin round, 2 go back around at the same time but one stays revealed for a few secs, the one that stays out is the one you need.

e.g D F C, but D+F spin round slightly before C, so you need C.
