Here's another idea.
Guess the draw: A staff member will use the admin rocket to shoot in the sky and draw something. It can be a letter, a word or a number, or even an object/animal.
The first person to find out what the staff member is drawing win 1 event point.
Rules: No rockets allowed for players. To make this easier, the staff member could even be in the players team to avoid being flipped and stuff like that.
