Welcome to the International Simulation Football League, a league that gives you the opportunity to create your own player, go through real drafts, join teams managed by real users, and fight for a chance at the Ultimus trophy!

Started in 2016, the ISFL has been through 50+ seasons, with each season lasting about 2 months of real time. You can be fully active just by spending 15 minutes a week earning TPE (think experience points). Earn TPE by completing tasks such as weekly predictions, responding to short writing prompts, or even playing fantasy football with players in the ISFL itself.

We even have a rookie discord staffed with users ready to answer any question you throw at them. The rookie server is the perfect place to get to know other users, old and new. With pre-season prospect bowl games to get you integrated into the league during the off-season, there isn't much downtime!
