Count out loud in turn from 1 to 14 around the circle. The starting rule is always: you cannot say the number 7.

If the group completes the round, whoever landed on 14 makes a new rule — for a number that does not already have one.

• Ideas: swap 5 for 8 · swap 5 for “hello” · swap 5 for raising a hand.

Keep going until every number has a rule. Break a rule: everyone drinks 1 and the sinner drinks 2 — and the round restarts.
