# Vacation is OVER…

Grudge Ball Each team starts with 10 Xs Each group gets a question. If you get it right then

you automatically get to erase 2 Xs from the board. You can take them both from one team or split them. (you can not take Xs from your own team) Before you take off the Xs, you have a chance to

shoot the ball into the bin for the chance to increase the amount of Xs you get to remove. A shot made from the #1 line allows you to erase 4 Xs and a shot made from the #2 line allows you to erase 5 Xs

If your team loses all of their Xs, you can gain them back by answering a question correctly AND making a basket (4 Xs from the 1st line and 5 Xs from the 2nd)
