All players sit around a circular table, and cover the table in shots. The game begins with all players putting their heads down on the table. On the count of three each player looks up and stares at another player. If you are looking at someone who isn’t looking at you, you are safe. If you are looking at someone and they are starting at you, it turns into a competition between you both to see who can shout Medusa first. Last person to shout it has to do a shot. If it’s said at the exact same time you both take a shot.
This is continued until there are no shots left on the table. It’s more enjoyable if you have a variation of shots.
