10. Minesweeper
Players arrange 16 (or more) identical shot glasses and fill 8 with cheap vodka and 8 with water. Arrange them randomly in a square and take turns choosing and shooting.
11. Pizza Box
Players must rip off the lid of the pizza box, then take turns flipping a quarter into the top of the box. Wherever it lands, the player draws a shape, and inside the shape writes a rule or action.
If you land inside an already drawn shape, drink, and do whatever it says to do.
