Backgammon

A race where the shortest route is rarely the safest. Two dice, fifteen checkers each, and the constant question of whether to leave a man alone.

The rules

  1. The board has twenty-four points and each player has fifteen checkers. The two players move in opposite directions, each towards their own home board.
  2. Roll two dice and move one checker for each die, or the same checker twice. A double is played four times, not twice.
  3. You must use both dice if there is any legal way to do it. If only one can be played, you must play the larger.
  4. You may land on any point that is empty, has your own checkers, or holds exactly one of your opponent's. A point held by two or more enemy checkers is closed to you.
  5. Landing on a lone enemy checker, a blot, sends it to the bar. It must re-enter in your opponent's home board before they may move anything else.
  6. Once all fifteen of your checkers are in your home board you may begin bearing them off.
  7. The first player to bear off all fifteen wins. Winning before your opponent has borne off any is a gammon; winning while they still have a checker on the bar or in your home board is a backgammon.

There is no doubling cube here. A gammon and a backgammon are recorded, because they are the most satisfying thing that happens in a game of backgammon, but a win counts as a win for your rating.

Playing it here

  • Against a person or the bot. The bot needs no account and starts at once. To play a person, be rated and keep your games, you need an account: an email address and a password.
  • At your own pace. Every move has a deadline you both see, from five minutes to a week. A game can take an evening or it can take a fortnight.
  • Nothing to buy and nothing to win. No stakes, no prizes, no boosts, no undo. The only thing on offer is a place on a leaderboard, and only if you want one.
  • Every game can be checked. Anything decided by chance comes from the game's seed, and the seed is published the moment the game ends, so any finished game can be replayed and verified by anyone. See fair play.
