Using the game
This free version is provided for personal entertainment. It does not offer prizes, betting, professional predictions or official NFL services. You do not need an account.
Results and availability
Historical inputs may contain corrections, and our simulation deliberately simplifies football. We do not promise that an outcome predicts a real matchup or that service and local records will always be available. Clearing browser storage removes your progress.
Names and data
Team and player names identify historical facts and remain associated with their respective owners. No endorsement is implied. Historical data from nflverse is attributed under CC BY 4.0 as described on the methodology page. That data license does not grant rights to third-party trademarks or images.
Changes
When a release changes the data or model, it uses a new version. The scope and privacy description will be updated before introducing accounts, online rankings or advertising.
