How to play
Setup. Every player puts five tokens into a shared bank beside the board. Tokens belong to nobody until they leave the spiral.
Entering. On a throw of 1 or 6, take one token from the bank and set it on space 1 at the centre of the spiral.
Moving. On a throw of 2 to 5, advance any one token or stack on the board that many spaces clockwise along the spiral. Tokens that land together become a stack (up to five). You may move a whole stack or split off part of it.
Collecting. A throw that carries a token or stack past space 9 takes it off the board, and the player who threw keeps those tokens.
Bank empty. Once the bank is empty every throw, including 1 and 6, is a movement throw.
End. The game ends when the bank and the board are both empty. The player holding the most tokens wins.
Traditional accounts leave a few details open; here a throw larger than the distance to the exit still clears the stack, and a throw with no legal use is simply passed.
