2 or More
A player starts by rolling a dice, if that player rolls a 1 they take a drink. If they get a 2 or a 5, they pass the dice to the next player (clockwise). If the player gets a 6, they invite another person to take a drink with them. If the player rolls a 3, the person to their right has to take a drink. If they roll a 4 the person on the left drinks.
If you roll the same number twice in a row you have to take a shot. If you roll the same number three times in a row you get to nominate someone else to take a shot.
