Cuyo is a Tetris-style puzzle game for up to two players. The player controls falling blocks of various types which change with each level. For example, in the first level, the player has to connect differently colored cartoon faces to each other. When enough blocks of the same type are connected, they explode. Usually the level goal is to destroy a certain number of special blocks at the bottom of the screen; these special blocks explode when blocks adjacent to them explode (in some levels, only when this is accomplished through a chain reaction).
