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

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!
