The game begins with one player calling the direction of play by saying, "I propose a game of XXXX! To my left..." or "To my right..." followed by a sequential series of numbers beginning with one. Players are arranged in a circle, facing inwards. As the game progresses, each player in turn must recite one to four numbers, counting in sequence from where the previous player left off: Saying one number (e.g. "one") passes the game to the next player in the circle in the initial direction. Saying two numbers (e.g. "one, two") passes to the next player, but reverses direction. Saying three numbers (e.g. "one, two, three") passes in the initial direction, but skips a player. Saying four numbers (e.g. "one, two, three, four") reverses direction and skips a player. If a player makes a mistake, then they suffer a small to moderate drinking penalty (e.g. 2 fingers of drink) and then restart the game from 1. The game progresses by counting up from 1 to 21, with the player who calls "21" suffering a drinking penalty before the next round starts. The loser may add 1 new rule to the game, and starts the new round.
