This game requires a bunch of dodge balls, but it’s really fun.
First, split your large group into small groups (say you have 50; split them into 5 groups of 10).
Next make one big circle or square with all the people, and send one of the groups in the middle. The surrounding groups sit down while the group in the middle stands up.
Now the surrounding groups will roll all the dodge balls towards the group in the middle, which will try to dodge all the balls coming at them in every direction. Once they get hit they are out. The last person standing is the winner.
After you have Group 1 go, have Group 2 take a turn, and so on. At the very end have all the winners come up to determine the super, ultra, mega winner.
Variation: Start with one ball and increasingly add more and more lava balls
