Introduced to me by Great Greta as 'bee bim baddle boom'.

#To make decisions

Is a game that can be used instead of 'rock, paper, scissors'.

Each person is assigned even or odd Both people say 'bee bim baddle boom' and shake their hand on each word. Each person holds out between 0 and 5 fingers when 'boom' is said.

The sum of fingers is taken - the person who had been assigned the parity (even or odd) that the sum is wins.

#For betting

Can also be played as a betting game, with people shouting a number as the fingers are revealed. If they guess the sum of fingers correctly they win the round. Some variants play to three rounds.
