Challenge anyone, in any league, on any platform, to a one-week head-to-head matchup. Open Field's scoring engine harmonizes different league formats, so a PPR roster versus a standard roster is always a fair fight.
No shared league required and no scoring-system math — pull out your phone, send a challenge, and have a result by the end of the games.
Both rosters are evaluated on the same neutral scoring card, so neither player is advantaged by their league's format. Same players, scored the same way, every time.
Connect your Sleeper or ESPN league and your current roster auto-fills your challenge lineup — or enter players manually if you'd rather.
Pick the week, lock rosters before kickoff, and the winner is settled when the last game of the week ends. Rematch the same opponent every week if you want.
Open Field challenges are included with a free WaiverWire account. No entry fees, no tokens, no credits — and you can run multiple challenges at once.
