People waiting for the "must-have" puzzle game for the Nintendo DS will keep waiting. Polarium makes great use of the DS' touch screen, but doesn't pack enough puzzle punch to entertain gamers for more than short bursts of time.
The game consists of white and black blocks that switch colors when pressed. Gamers use the stylus to create horizontal lines of uniform color which disappear, or to transform the entire screen into a single color with one stroke of the stylus, depending on game mode. Polarium also lets gamers connect wirelessly with a friend for competitive races, or to trade custom-made puzzles.
Polarium doesn't have any bells and whistles
