No player may change or discard any die during a match. The Director shall impose one penalty point on any player who does so and may initiate further disciplinary action. Director may chance dice on his own initiative at anytime or, on request of a player, at most twice during a match at the start of a new game. At the start of a new game, either player may request that the four dice in use be mixed. In this case, the demanding player shakes the four dice together in one cup and rolls them out.
Opponent then chooses first and third die.
Player shall reenter any checker on the bar before moving any other checker. No player should move any checkers during an opponent's turn. Deviation from proper moving procedure may result in an adverse ruling in case of dispute. Checkers which have been borne off must be kept off the entire playing surface for the rest of the game and putted in order into the proper space. Failure to observe these procedures may result in an adverse ruling in case of dispute.
