Real backgammon
Every rule, the way the board plays.
- Hitting, the bar and entering from it
- Bearing off, including the higher-die rule
- Gammons and backgammons count double and triple
- The game makes you play the larger number when only one fits
The cube
Matches are won on the doubling cube as much as the dice.
- Double, take or drop
- The computer weighs its position before it takes
- Play a single game or a match to 3, 5 or 7
Play a friend
Pass and play on one device.
- Both players type their own name
- A handoff screen names whoever is up next
- The board turns so your checkers are in front of you
Computer opponents
Three levels, and the top one thinks ahead.
- Easy, Normal and Hard
- Hard looks a roll ahead before it commits
- Legal moves are highlighted, so nothing is a guess
See it in action.
