This one starts out simple, but don’t be fooled. Math is required, and it pays to be attentive. The first player says the number 'one', the second player says 'two', and so on. Continue around the circle until someone gets to seven, or any number divisible by seven. The player must then say 'buzz'. If they forget to do so, they drink. If they say buzz at an incorrect time, they drink. Good luck. Make your fourth grade math teacher proud.
