Sigma Chess

Sigma Chess is an excellent chess game that uses multiple intelligence engines to produce its moves.

The board can be set up in several different ways, including both a 2D and 3D board. With the 2D board, you can view the move history and take notes. With the 3D board, on the other hand, you can only make moves with the mouse.

You can also set the board color, size, and type of pieces. There are also charming drawings intended for younger players.

Another interesting feature is that you can adjust the game's difficulty level by controlling how smart you want the artificial intelligence to be.
