Just a weekly pool where you pick vs the spread who you think will win. I was tied for best in the week, but the tiebreaker is "total points scored." I picked 34, the other guy picked 42. Since the combined score was 41, and 41 is closer to 42 than it is to 34, I lost the week.
At the start of the season, every pays $17 ($1/week). If you win the week, you get $21.75 (based on the number of people we have in the league). At the end of the season, the top-3 players get a prize as well (don't remember how much offhand, roughly $60 for first, $40 for second, $25 for third.).
It's just a bunch of friends playing, so it's fun to "compete" against each other.
