For this game players need a bottle of beer (or other drink in a bottle) and several used 'caps' from beer bottles.
Players sit in pairs facing each other across a table and position their beer bottle standing in front of them. Each player places a beer cap upside-down on top of the bottle in front of them.
Players then take it in turns to flick or throw their caps at the top of their opponent's bottle in front of them. Each time a cap is knocked of a bottle the player whose bottle the cap is knocked off must drink two fingers of their drink.
The winner is the first person to have three successful attacks of their opponent's bottle. The loser must down the rest of their drink.
The players then rotate so they take on a new opponent.
This game encourages competition and is highly addictive. The drinking element can be increased or decreased as required.
