Designed to use the same board and pieces provided in a standard Chess set, Arimaa is intended to be difficult for computers to play. The number of possible moves at each turn in Arimaa is about 500 times that of Chess.
There is a reward of $10,000 for the first person or company who can build a computer program that can defeat a selected human Arimaa player prior to 2020.
The complete rules of the game are available at the http://www.arimaa.com/ website where visitors can also play the game online with others.
