Play Colossus Chess X Online

Colossus Chess X came out in 1988 for the Amiga, developed by CDS Software Ltd. It was one of the stronger chess programs available on the platform at the time, offering a solid digital opponent when finding a human player wasn't always easy. The game didn't try to reinvent chess; it focused on providing a clean, functional way to play.

You control the standard chess pieces, aiming for checkmate against the computer or a friend. The game includes a large opening book, timed matches, and a blindfold mode where pieces disappear after moving. You can also practice with mate puzzles or switch between 2D and 3D board views. The pacing is deliberate, and the difficulty scales to challenge both newcomers and experienced players. It feels like having a serious, adaptable chess partner always ready for a game.
