I have my own gameshow. I got it from some guy a long time ago, it isn't mine, but I fixed a few events up.
Simply, you ask a multiple choice question with four answers and label them A-D
You go in the booth you believe the answer is and if you're right you survive and the wrong ones die. My only problem right now is that typically people all crowd in the right booth when they automatically see someone walk to one. Gets annoyin'.
If you guys want, PM me and I'll host it. Might even make a topic, but I'll pass it so only people I think are legit get in.
