Backgammon against the computer
The classic board game with dice, played with full rules: 15 checkers each, hitting, the bar, bearing off and gammon. You play white and the computer plays black on three levels – from a random beginner to an opponent that calculates all 21 possible replies.
How to play
Backgammon is played on a board with 24 points (the triangles), and each player has 15 checkers. You play white and move from point 24 towards point 1 in the bottom right corner, while the computer plays black in the opposite direction. Both players start by rolling one die each and the higher die starts, playing both numbers. After that you roll two dice every turn and move one checker the number on each die, or one checker both numbers. A double counts four times, so 4-4 gives four moves of four points. You may not land on a point held by two or more of the opponent's checkers, and you must use both dice if it is possible. If only one die can be used, you must play the larger number when that is possible.
A single checker on a point is called a blot. If the opponent lands on it, it is hit and placed on the bar in the middle. A checker on the bar must come back in through the opponent's home board before you may move anything else. When all 15 of your checkers are in your home board (points 1–6) you start bearing them off: a die takes off a checker from the matching point, and a higher die may take off a checker from the highest occupied point when no checker stands further back. The first player to bear off all 15 wins one point, a gammon (2 points) if the opponent has not borne off a single checker, and a backgammon (3 points) if the opponent also still has a checker on the bar or in the winner's home board. The doubling cube is not used here.
To play, tap one of your checkers and then one of the highlighted destinations – a destination that needs both dice is shown too. Undo takes back moves within the current turn, and Done ends the turn. If you cannot move at all, the turn passes automatically. Easy plays random legal moves, Medium weighs the pip count, blots, made points and primes, and Hard also looks one roll ahead at all 21 possible dice outcomes for your reply.
