Pokémon Puzzle Challenge

The objective is to remove blocks from the player's puzzle grid as new ones appear from the bottom. Placing three or more blocks of the same color in a horizontal or vertical line will cause them to disappear. Players can also perform combos by clearing more than three blocks at once, as well as chains when falling blocks from one clear cause another set of blocks to clear. A game typically ends when the blocks reach the top of the grid, at which point the player loses.

In competitive modes, players can perform combos and/or chain clears to cause objects called garbage blocks to fall on their opponent's grid, further filling it in an attempt to cause them to lose. Concessions are made due to the game's limited screen size: Puzzle Challenge features a puzzle grid size of only 6x9 blocks, compared to the 6x12 grids of other Puzzle League games, and the opponent's grid is not visible, with a small meter instead indicating how close they are to losing. The game features six primary modes of play. Marathon involves playing infinitely until the grid is filled and the player loses.

Challenge is a competitive mode that pits the player against several computer-controlled opponents, framed as the player traveling around the Johto region challenging other Pokémon trainers and gym leaders. Time Zone challenges players to achieve the highest score within a time limit. Line Clear is a stage-based mode in which players must clear a certain number of lines to advance. Puzzle involves clearing specific arrangements of blocks using a limited number of moves.

Garbage is an infinite mode similar to Marathon, but with increased difficulty due to garbage blocks frequently appearing on the grid. Using a Game Link Cable, two players can compete in standard versus play, Time Zone, or Line Clear. A training mode is also available. The game is heavily themed after Pokémon Gold and Silver , featuring characters and remixed music from those games.

Players can choose between different Pokémon that appear as part of the user interface. At the start of the game, players only have access to Chikorita , Cyndaquil , and Totodile , but can unlock six more Pokémon by completing specific objectives in Challenge mode then defeating their trainer. Four additional Pokémon appear as eggs, which can be hatched and used in Marathon mode after achieving a high score in the other modes.
