RohuGammon is backgammon optimized for the small screen. The board is scaled to maximize playing area. Checkers are over-sized for easy access, and the number of checkers on a point is displayed.
Play against a friend, or against the computer. The computer has five separate AIs with different strategies. Some are aggressive attackers; others play defensively. You never know which strategy the computer is going to employ, so its nearly impossible to guess how the computer will play.
To speed the game, you can enable auto-roll and disable undo, creating a fast-paced game. Play multi-game matches where scoring a gammon or backgammon can earn you more points. When the outcome of the game seems inevitable, hit "auto pilot" and let the computer finish the game for you.
