Royal Game of Ur

Roll four binary dice, then move one of your seven pieces by the number of marked tips. Bring a piece onto the track, move one already in play, or bear off with an exact roll.

Landing on an opponent on the shared track sends that piece back to its start. You cannot land on your own piece. The central rosette protects its occupant, and every rosette grants another roll.

A zero or a roll with no legal move passes the turn automatically. The first player to bring all seven pieces home wins.
