There are two draw positions in this game. The first is with both hands out, forefingers extended, as if you’re a two-gun sheriff. The second is with both hands up, as if surrendering.
Everyone draws at once by slapping both hands on their knees, then quickly showing a position. If they match the leader’s hand position, they’ve lost. If they’ve picked the opposite, they’ve won.
Do it again, trying to go a little quicker each time.
