|Each player has three coins in their hands. It doesn't matter what kind they are just as long as they're coins. Everyone sits around a table with both hands under the table with the coins.
Everyone secretly decides how many coins they want in one hand. Then everyone places their hand (only one) on the table. One person is it and they guess how many coins there are TOTAL between everyone who is playing. Then the next person goes and so on.
After everyone is done guessing everyone shows their hands and whoever guesses the right amount is out. Meaning that everyone else has to drink. They have to drink how many coins there were total. The game keeps going until you can't drink anymore.
You can also play it where the person who gets out is out for the rest of the game and you keep playing until only one person is left. That person must finish their drink.
