A person begins by counting starting with the number "1". The next person follows by counting "2". This continues until a number is reach which includes "7", a multiple of seven or any variation of the number "7" (i.e. 7,14,17,21,27,28,35,37,70,71,72 etc.) These numbers are called "sevens". If it is your turn and the number is a "seven" then you say "pass" instead of the number. If you mess up and say a "seven" instead of "pass" you are out and the game begins again with all other players. It is best to keep a rhythm while playing.
