You need:
A deck of cards, an empty bottle, and 3+ people

Place a deck of cards on an empty bottle. Each player blows cards off the deck on the bottle in turn. The one who blows the last card off the bottle must drink one beer.

Special rule: If an ace is spotted among the cards that were just blown off, the “blower” must drink a beer. If two aces were spotted, they must drink two beers and so on.
