Pokémon Puzzle Challenge

Pokémon Puzzle Challenge features Pokémon characters in a version of Panel de Pon, known as Tetris Attack in North America. Panel de Pon featured unique characters for both player-characters and opponents; similarly, Pokémon such as Pikachu, Pichu, Cyndaquil, Totodile, and Chikorita appear as playable heroes, while Gym Leaders, trainers, and the Elite Four from Pokémon Gold and Silver appear as opponents, all of them utilizing a single Pokémon used in Gold and Silver. It features the ability to collect Pokémon by battling trainers in order to unlock new Pokémon to play as. Similarly, the music in the game was taken from Gold and Silver. Players attempt to meet a goal, achieve a high score, or outlast opponents by preventing blocks from reaching the top of the player's playingfield. The game has three modes of play — single player, multi player, and training modes. There are also several other sub-modes: Marathon, Challenge, Time Zone, LineClear, Puzzle, and Garbage!.
