This is a straightforward 1–100 racing game, at least as present in Love's version, which features "adapted" rules (his term, unexplained). Players roll and move as expected, picking up 1 token if they are the first to reach or pass each of the 18 holes. (It is not clear if these successful players are supposed to pause at each hole and allow others to catch up, although "excess" rolls may be "counted against the next hole.")
Simple hazards are present in the form of hedges or bunkers, which cause players to lose 1 turn, or streams, which cause players to lose 1 turn and return to tee off from the start of the hole.
The winner is the first player to reach 100 exactly, claiming the remaining 3 tokens from the original 20-token pool.
