Puzzle Link is a tile-matching game in which the player must clear away blocks which occupy some of a 9×10 block grid.
The player clears these blocks by linking together two or more sections of each block type. This linking is accomplished by firing one-block-width units of pipe from a launcher at the bottom of the screen, which the player can only move left or right.
The 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 hit by the first fired unit of a new pipe. An existing pipe can be canceled.
