I wasn't there on the official day so i'm going to write about the test day.
Our game was called beat the ball. We taught it to the juniors It went OK not many people liked it and people look very bored while we were playing it. They got all the rules but just didn't enjoy the game. The way to play our game is 6 people stand in a circle then you pick a runner and the runner has to run around the circle before the people in the circle get the ball back to the start.
