Tetris!...? I dont think so!

The game really brings lots of fun for 2 player or 1.The puzzle action in Pok'mon Puzzle Challenge is presented in a wide range of difficulty levels, which makes the game suitable for players of all ages. To help players learn the basics, a thorough in-game tutorial is available from Professor Elm in the Training Mode.

Pok'mon Puzzle Challenge features an engrossing single-player adventure, plus a non-violent Two-Player Mode where two friends can compete against each other in an action-packed puzzle match. To participate in Two-Player Mode via the Game Link Cable, each player must have a Game Boy Color and a copy of Pok'mon Puzzle Challenge.
