Bump is a fun game for 2 or 3 players! You supply two dice, and 10 connecting cubes per player. Students take turns rolling the dice, then covering the corresponding number with a cube. When a player rolls a number that is already covered by their opponent's cube, they may "bump" that cube and replace it with one of their own. If a player rolls a number they have already covered with one of their own cubes, they stack a second cube on top and "lock" that number. The first player to use all of their cubes wins.
