In order to exit the player's base it is necessary for a six to be thrown, which results in putting a piece on the coloured square joining the base known as the "doorstep". However, if on the very first throw "snake eyes" (two ones) is thrown then all player (possibly partner's depending on which rules) pieces come out of the base onto the doorsteps - known as "out all bits". Play then continues with the next player. If on rolling snake eyes on the first throw a player again throws snake eyes on their second throw all of their pieces return to the base. Under WAFU Rules, a player must call "snake eyes" prior to his first roll to benefit from rolling two "ones". He cannot do this retrospectively. If playing with a partner, then only his pieces come out not his partners.
