 OFFSET 1,1 COMMENTS You and your father alternate counting. For every number that is divisible by 4 or contains a 4, substitute "buzz". For every number that is divisible by 7 or contains a 7, substitute "bang". The game is over if a mistake is made. The sequence is the "Buzz buzz bang bang" sequence, meaning it has the numbers that get 2 buzzes and 2 bangs in this game.
