My league actually tried the survivor pot a few times but people werent getting in enough to keep it going.
My league did have a strike pot that got up to 15,000. It was one dollar to get in and based on your average you had to get strikes in certain frames. So the higher your average the more strikes you had to get. There was one guy a few years ago who almost won it. He was in the third game on the last strike he had to get he hit the pocket flush but left the 10 pin he was pissed of course. We stopped the pot and just divided the money evenly amongst the teams.
Wow 15,000 dollars is a lot. I don't know what I would do if I left the bowling with half of that money.
