In the baseball variation of quarters, four glasses are lined up in a row, each one slightly taller than the previous one, each marking single, double, triple, and home run. Beyond that, the game is played much like real baseball, each quarter flip representing a hit or an out and the game runs for nine innings. Every shot glass is filled with a drink and refilled after each hit. You can play by yourself or in a team of two, and the winner is whoever has the most runs after nine innings. In a tie the game goes into overtime and hard drinks are brought in (unless you have the balls to play the entire game with shots).
