You've got the slide rule, the water slide, the slide projector, the slide guitar and the Electric Slide. But none of them is nearly as fun as the new slide-action puzzle game for Nintendo DS called Pokémon Trozei. Nintendo systems have always been home to great puzzle games, and the added abilities of Nintendo DS add a new dimension to game play. Players use the touch screen to slide Pokémon puzzle pieces side to side or up and down. Lining up four in a row (vertically or horizontally) makes a Trozei and clears the screen. When players create continuous Trozeis by lining up three in a row, then two in a row, they will clear the screen faster and increase their score. Pokémon Trozei features two single-player modes and two two-player modes. As an added bonus for Pokémon fans, players also try to add each of the more than 380 Pokémon featured in the game to their Trozei Lists. Players can increase their chances of finding rare Pokémon by playing wirelessly with friends. Pokémon Trozei is easy to pick-up and play, but you'll have a tough time putting it down!
