Monte Carlo Engine

Run 10,000 to 100,000 full-bracket simulations. Every pick propagates forward through the entire tournament to produce calibrated path probabilities.

Configurable Levers

Tune Four Factors weights, roster experience, coach history, tempo effects, and more. Override any matchup with injury, site proximity, or momentum adjustments.

Contest Strategy

Ownership estimates reveal how the public is picking. Game theory recommendations adapt to your pool size — from chalk for small pools to contrarian paths for large ones.
