Backgammon

Sit down at the board and roll the dice. Backgammon is one of the oldest board games in the world, played for something like five thousand years.

This is a backgammon app built around a single principle: stay faithful to the classic rules. No flashy gimmicks, no ads, no in-app purchases. Just an accurate board and the satisfying feel of moving your checkers.

FAITHFUL TO THE CLASSIC RULES
Twenty-four points, the bar, and the bear-off tray. Legal moves are determined strictly by the rulebook, including passing when no move is available, playing four moves on doubles, and the requirement to use the higher die when only one can be played. Hitting and re-entering from the bar, bearing off, and scoring gammons and backgammons at double and triple value are all handled correctly. Valid destinations are highlighted automatically, so you can play with confidence even while you're still learning.

THREE LEVELS OF COMPUTER OPPONENT
The CPU chooses its moves using Monte Carlo tree search. Pick from Easy, Normal, or Hard: Easy makes a patient practice partner, while Hard will punish a loose blot. Dice are rolled with a Mersenne Twister random source, so every roll is fair and unbiased.

WATCH THE CPU PLAY ITSELF
Prefer to sit back? Spectator mode lets two computer players face off at the level you choose: Easy, Normal, or Hard. Pause at any moment to study the board, or step forward one turn at a time to follow each decision.

LOCAL TWO-PLAYER
Pass one device back and forth and play face to face. No setup, no connection required. Just start a game.

THE DOUBLING CUBE
Offer, accept, and decline doubles. The computer reads the position and will double you when it is ahead, or drop when it is beaten. Gammons and backgammons are multiplied by the cube, and the Jacoby rule can be switched on in Settings.

GOOGLE PLAY GAMES
Wins and win streaks are recorded to leaderboards and achievements, so you can measure yourself against other players.

HOW IT FEELS
Checkers arc across the board, and a hit blot is knocked back to the bar. Sound and haptics answer every move, and a win is celebrated in proportion to its size, from a plain single to a backgammon. A fading ring marks the move just played, so you never miss what the computer did. Misdropped a checker? You can take one move back until the next roll.

DETAILS THAT MATTER
- Live pip counts for both sides
- Sound and haptics, each toggled separately
- Localized in English and Japanese
- Automatic match history
- Both tap-to-select and drag-and-drop input

No ads. No in-app purchases.
Just a quiet game, played by the classic rules.
