As a tiny Choose-Your-Own-Adventure booklet, based on the 1958 of the same name, you play as a young child playing with your friends. The game: throwing pebbles at passers-by.
Pebble in hands, target acquired, you must roll some dices to determine your chances at a hit. You are then met with a choice: wait a bit longer (the target is not close) or throw it now - sending you towards one of two different endings.
The writing style of the game is very playful, almost childishly so, which works so well since you are a child doing childish things. It is also very visual in the limited descriptions - especially with its even-numbered passages.
A cute thing to play for a five-minute break!
