Cocktail Tip
Add the ingredients to your cocktail shaker (or jam jar) with cubed ice and shake briskly for about 10 seconds. Strain and pour into a glass leaving the ice in the shaker. This is important for chilling and diluting the drink to the right proportion, plus a fun way to entertain.
Beergammon
Another adaptation of board games, this one obviously to Backgammon. A pretty tame game, that just gets tamer. Supplies: you and a partner who wants to play Backgammon, the game itself, and some beverage. Low-mid buzz factor, depending on how fierce the competition is.
Play the game as usual. Any time one of your pieces gets sent to the bar, drink. As well, each time you take a piece off the board, drink again. Pretty straightforward.
