Terms of use

By using NFL Optimizer you agree to these terms. The plain-language summary: use the tools freely, expect honest math, and don't treat any output as a promise about football or money.

What the tools are

Deterministic calculators. The optimizer provably maximizes the sum of the projections you supply under the roster rules you select — it does not predict outcomes, and its outputs are only as good as your inputs. The sample slate shipped with every tool is fictional placeholder data, labeled as such, for demonstrating the math.

No gambling advice

Nothing on this site is betting or wagering advice, a guarantee of winnings, or an encouragement to gamble. Daily fantasy contests involve real financial risk, and most participants lose money over time. You are responsible for complying with the laws of your jurisdiction and the rules of any platform you play on. If gambling is a problem for you or someone close to you, contact the National Council on Problem Gambling at 1-800-522-4700 (US).

Trademarks

DraftKings, FanDuel, Rotowire and all related marks are trademarks of their respective owners. This independent site is not affiliated with, endorsed by, or sponsored by any of them. Platform names and roster-format descriptions are used nominatively, to describe what the calculator computes.

No warranty

The tools are provided "as is" without warranty of any kind. While the solver is exact and unit-tested, we make no promise of fitness for any particular contest or purpose, and we are not liable for decisions made on the basis of tool output — including entry fees lost using a lineup built here.

Changes

These terms may be updated; continued use after a change constitutes acceptance. Tools and pages may also change or be retired — this is a free utility site, not a service contract.
