[edit] Background

This is a deceptively simple puzzle game based on the DS touch-screen interface. Players have to carefully follow a path on the lower screen with the stylus according to cues on the upper screen. A challenge mode demands quick thinking, while a "checkmate" mode features more complex challenges, and two players can race each other in the versus more.

[edit] Gameplay

Prepare for brain-busting puzzles and fast-twitch action as you draw lines to flip black and white tiles and make patterns and puzzles disappear!

[edit] Features

  • Ready ...set...SWITCH - As patterns relentlessly fall from the top screen, draw lines to reverse their polarity and make them disappear. The more you clear, the faster they come...
  • Use your head - A hundred single-screen puzzles await! Each can be solved by drawing a single line, so take your time and think them through. Not only that, but you can design your own puzzles and send them to a friend via wireless link!
  • Cross out your pals - Play wireless multiplayer matches against a friend; as you clear lines, they'll appear on your opponent's screen, which is visible to you on the upper screen of your DS. Clear lines with question marks on them to get power-ups that make your lines clear faster, block out your foe's border, reverse his or her tiles and more!
