SuicideLeague is really fun type of fantasy football!
What is a Suicide league you ask? Some people refer it as survivor pool, elimination or knock out. Each week you pick one NFL team to win their game, if that team wins you move on to the next week, but you can not pick that same team for the rest of the regular season. If that team you picked loses, you are eliminated.
What i really like about SuicideLeague is that it is really simple, does not take very much time, and it's exciting!
SuicideLeague is completely FREE! You are welcome to create and join public and private leagues, and invite all your friends.
