Mexican Quarters Drinking Game: One person is given the quarter and chooses one of the other players to challenge. They spin the quarter and before it stops the person spinning the quarter must cover it with one hand. The chosen person then must guess if it’s heads or tails. If wrong, the spinner spins the quarter again and the player must drink for as long as that quarter is spinning. The spinner then covers the quarter again before it stops spinning and the player has to then guess again.
