Polarium

Polarium is a simple, stylish puzzle game you play entirely with the Nintendo DS touch screen and a stylus. Draw lines to flip black and white tiles and make patterns and puzzles disappear. Use the stylus to draw a stroke, flipping black and white tiles to change and match their color. Three game modes and scores of puzzles will put your puzzle-solving abilities and stylus skills to the test. Challenge a friend to a duel over a wireless connection.

• 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.

• A hundred single-screen puzzles await! Each can be solved by drawing a single line, so take your time and think them through

• Play wireless multiplayer matches against a friend; as you clear lines, they'll appear on your opponent's screen

• Design your own puzzles and send them to a friend via wireless link
