InCube Games has presented a free version of its self-titled chess game in a real 3D field (8x8x8), and has updated the basic version of the program. Also, the price for the basic version of the program has been lowered from US$3.99 to $2.99.

Here’s how the game is described: “InCube Chess is a new stage in evolution of the classic chess game, which is transferred into three-dimensional space. Overcoming limitations of two-dimensional classic chess, Chess InCube saves their traditions and basics, but invests a lot of new possibilities.”

The game requires Mac OS X 10.6 or later. It’s available worldwide exclusively through the Mac App Store in the Games category.
