Some friends and I were recently in a restaurant waiting at the bar for our table to be ready. We pulled out a single six-sided die and had a great time while the staff prepared the table -- we played the game Pig (complete rules). It's best with just a few players, but it can work with as many as are available. Pig is a press-your-luck game where the goal is to be the first player to reach 100 points... but every single roll is a risk. Give it a try!
