ONE AND DONE FANTASY

Terms of Service

Version 2.1  ·  Effective: June 2026  ·  Applies to: the One and Done Fantasy mobile application (the “App,” displayed on your device as “One & Done”)

The short version. One and Done Fantasy is free to play. There are no entry fees, no purchases, and no cash prizes — so these contests are games of skill, not gambling. You must be at least 13. One account per person, and each NFL player can only be used once per season per league.

These are the same Terms you accept inside the App when you create your account.

2. Free to Play

One and Done Sports is a FREE-TO-PLAY fantasy game. There are no entry fees, no purchases, and no cash or other monetary prizes. You will never be asked to pay to create or join a league. The App is free to use and may be supported by advertising (see Section 9).
