SimSlate rebuilds the whole tournament before lock: a 50,000-lineup field drawn from projected ownership, then 50,000 correlated simulations of the slate powered by AI-calibrated player models. Lineups are ranked by expected ROI against that field — not by adding up projections.
Free plan Run a real 1,000-lineup field simulation on the live engine — letter-graded outputs, no card required. Early Access ($49/mo) unlocks the full 50,000-lineup sim with exact numbers. Compare plans →Because one number never won a milly
Projected ownership is treated as ground truth — never renormalized, never smoothed. The generator fills 50,000 valid DraftKings rosters and calibrates until every player's exposure lands within a hard tolerance band of their projection. Scarce positions fill first, so the salary squeeze falls where real fields feel it.
Every player gets a right-skewed distribution fitted to their mean, volatility, ceiling and boom/bust odds. A Gaussian copula ties teammates, stacks and game environments together, then the engine scores the full field 50,000 times, pays out a top-heavy GPP curve — with duplication splitting prizes — and reports each lineup's ROI.
Contest simulation is only as honest as its scale. Other DFS sim tools cap the field and the sim count — and charge more for it.
Popular lineups get duplicated. SimSlate models expected duplicates for every field lineup from joint ownership, so a chalky build that "wins" shares first place — and its simulated ROI shows the dilution before you pay entry fees to find out.
Within every projected-score decile, simulated ROI is verified to correlate negatively with ownership. Lower-owned paths to the same score are worth more — that's the math of top-heavy payouts, and the engine won't ship a sim where it doesn't hold.
Four working exhibits built straight from the engine's statistics — no mockups, every dot computed live in your browser. Each one puts your hands on a piece of the machine that ranks your lineups.
42,000 particles hang under a living probability density. Scrub percentiles, carve the curve, and watch a bell curve re-fit into the skewed shapes the engine actually uses.
