Penalties for playing out of order, slapping the deck when no Boom was
played, being last to hit the Boom card, playing too slowly, etc. are
distributed in the form of tokens, with players starting with one
face-down token for each sound: Whizz, Bing, Bang, Boom (ordered low to
high). The player who is first to hit the Boom card gives a token to the
player who hit it last, but in all other penalty situations, players
must race to find the lowest face-down token they hold and give it to
the penalized player face up; whoever does so first gives the token away
while all other players keep theirs and reshuffle them. When one player
gives his Boom token away, each player scores one point for each token
he holds. When a player has scored 15 or more points, the game ends and
the player with the fewest points wins.
