Rule highlights

Setup, play, winning, and house rules

Setup

  • 2 players. On your own, play against the computer.
  • Each player starts with seven pieces in the waiting area. The board has three rows of eight, and the middle row is shared.

How to play

  • On your turn, throw four tetrahedral dice. The number of white tips facing up, 0 to 4, is how far you move.
  • A waiting piece enters on that square of your column, from the first to the fourth. A piece already on the board moves that many squares forward.
  • You may not land on your own piece. A throw of 0, or a throw with no legal move, passes the turn.
  • Tapping a piece previews where it lands. Tap it again, tap the target square or press Move to confirm.

Winning

  • Landing on a rosette — the fourth and fourteenth squares of your own column and the eighth in the middle — earns another throw.
  • Landing on an opposing piece in the shared column sends that piece back to the waiting area. A piece on the central rosette is safe, so you cannot move onto it.
  • Bearing off needs an exact throw. The first player to bring all seven pieces home wins. A player may also resign.
