Built on NFL constructions. QB stacks, bring-backs and the salary shapes that actually cashed on Sunday main slates, with showdown graded on its own corpus.

Scored against real winners

Every lineup gets a Historical Pattern Score: how closely its shape matches lineups that cashed in real DraftKings GPPs.

Stacks, groups and rules

Pick the QB, pick the team, bring-backs, game stacks, at most and at least rules, exposure and ownership caps, minimum unique players.

Entries in, lineups out

Upload your DraftKings or FanDuel entries file, fill every entry from Built or Saved, and export straight back.

Is this a simulator?

No. It is a lineup builder that grades construction. Every lineup you build is scored against 11,000 lineups that cashed: salary shape, stack, bring-back, with the hit rate for each factor.

Does the sample matter?

The 11,000 lineups are DraftKings NFL main-slate GPP cashes, 10-plus games. Showdown slates are scored on their own corpus, never on main-slate shapes.

Can I export to DraftKings and FanDuel?

Yes. Upload your entries file, fill every entry from Built or Saved, and download it straight back into the site. Export is part of every plan.

How many lineups can I build?

Rookie builds 20 a click, Pro 150, Sharp 500. Unlimited builds a day on every paid plan.
