Cuyo

See also: Cujo, a book by Stephen King

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 disappear. Usually the level goal is to destroy a certain number of special blocks at the bottom of the screen; these special blocks explore when blocks adjacent to them disappear (in some levels, only when this is accomplished through a chain reaction).

Some of the more complex levels have

• changing blocks (e.g. darkening over time, changing into a different state, only revealing their type occasionally)
• changing environments (e.g. very quickly falling blocks)
• different block connection requirements (e.g. blocks can only connect diagonally)

The player loses when the level timeout is reached (there is a slowly lowering "curtain" which can reach to the bottom and, when it touches the blocks, stops the game) or when the blocks have reached the upper bound of the screen.

The game graphics and animations, while simple, are part of the player's motivation, since they change with each level. The constantly changing requiremens make Cuyo different from Tetris, where the main variation over time is speed and scoring.

Cuyo is open source software under the GNU General Public License, with binaries available for Linux and Windows. The game texts are English.
