11. 9. Results
The Catapult Game’s
goal is to knock all 3
soldiers down every time
the shooter launches a
ball.
Results must be tracked
(in yellow) by teams and
by each shooter ( e.g.
shooter 1 and shooter 2
from team 1).
Points are assigned by
the number of soldiers
down. One point for
each solder knock down.
Each shooter tries 5 times at each round. The maximum number of points each
shooter can make at each round is 15 (3 soldiers multiplied by 5 times)
