The game - Puzzle Link - Neo Geo Pocket Color | NGPC

Puzzle Link is a tile matching game in which the player must clear blocks that occupy one of a 9x10 block grid. The player removes these blocks by connecting two or more discrete sections of each type of block. This linkage is achieved by firing one-block-width pipe blocks from a player-controlled run to the bottom of the screen, where the player can only move left or right.

Pipes have as many varieties as the number of block types in a given level, and the type of pipe being fired is determined by the first block hitting the first burnt block of the new pipe. The existing pipe can be cancelled.
