Play is essentially the same as standard Anglo-American Checkers with short jumps, but with the addition of a 'roll-over' stage at the end of non-capture moves. Each player begins with twelve six-sided dice with the 'one' faces showing in the standard Checkers initial arrangement. Maximal jumping captures are mandatory, but after non-capture moves, a player increases the number on any other die by one (unless the die moved is that player's last piece). Any die showing a 'six' is a standard Checkers king that may move or capture backwards or forwards. Pieces that reach the opposite last row also become kings immediately, but the turn ends.
