Responsible Use

Lineup help, not guaranteed winnings

OpenField DFS is a lineup-building and strategy tool. It does not guarantee contest results, winnings, or profit. Users are responsible for checking DraftKings rules, player news, contest eligibility, age limits, and local laws before entering any lineup.

No gambling advice guarantee

Generated lineups are suggestions based on uploaded CSV data and user controls, not financial promises.

User responsibility

Final entries, late swaps, injuries, inactive players, salary changes, and contest rules must be reviewed by the user.

Age and location rules

Users must be legally allowed to play paid fantasy contests in their location.
