or how about a suicide football pool?
how it works..everyone puts in $ amount, like $100 for the full season. Get 100 people in, that makes pool $10k.
Before games are played each week, person has to put in 1 team they want to win, no point spreads, just straight up winner. If your team wins, you advance to the next week. If team doesn't win, you are out for the season.
You can only pick a team once during the season. After you pick a team, you can no longer pick that team for the remainder of the season.
At the end of the season, whoever is left splits the pot. At any point, if unanimous, the pot can be split by all remaining players. Example, if 5 players remain in week 14, they could all decide to split the pot.
I played last year, had 370 entries for $37k. I went out in like week 10. I think 7 people made it to the end. Same group this year is trying to get total 700 to play. Definately makes gameday bit more interesting.
