Based on the standard method of scoring for the game of Bowling, draw 10 "frames" as shown in the image to the left (above on mobile device).
You can choose your own method of scoring each frame. For us, we had a small group (two teams of three).
One player would toss the ball across the room toward their pins, then the first player form the other team would throw the ball back toward their pins. This would be repeated until each player from each team all had a turn to throw. We would then count that as the first "bowl" of the first frame.
Repeat this process on the next frame, and then complete all 10 frames.
If this doesn't make sense to you, and is too complicated, you can make up your own method of scoring...but just throwing the football at the pins is fun enough!
Have fun, and let us know how you enjoy the game!
