1. Divided into 5 groups. Each group starts
with 10 Xs.
2. Your group gets a question. If you get it
correct, you get to erase two X (2 from one
team or split ‘em up) from the board.
3. BUT, you can choose to take a trashketball
shot. From the 2 point line = 4 X; from the 3
point line = 5 X; Miss it= original 2 X
The team with the most Xs at the end WINS
