Ever felt these headaches handing out prizes?
First-come feels unfair
One quick round of rock-paper-scissors and someone always feels cheated.

Here's how the room lights up
Example use
No draw box, no number tags. Just line up the prizes and show the odds — a “which one should I go for?” game kicks off and the room's buzzing before anything's handed out. Put the ladder reveal on the big screen and it's the climax of the night.
Example use
Prizes and pairings all left to chance, so everyone's on equal footing. The host doesn't decide by hand, so no one cries “favoritism.” Deciding the prizes becomes the entertainment itself.
Example use
“First-come” prizes breed resentment. Here everyone picks while watching the odds, and the draw is verifiable by anyone afterward — so no one argues about fairness.
