How the simulator works
What Contest Simulation does with your pool: thousands of simulated contests, a realistic opponent field, correlated scores, and real payouts.
Run your first sim
Open the lineups panel, click Simulate, run the Contest Simulation sheet, and read what changes on your lineups when it finishes.
Contest Simulation settings
Every control on the Contest Simulation sheet: scenarios, Prefill from Contest, Contest Size, Entry Size, My Entries, and the Payout Structure.
Read sim results
What every number on a simulated lineup means: ROI, Win, Top 0.1, Top 1, Top 5, Cash, Lev, the scenario band, and the Best badges.
Sim scenarios
Simulate one pool against several contests in one run, compare a large GPP to a small one, and re-simulate after edits.
Select and rank after a sim
The Selection methods and Rank by options a sim unlocks, what DFS Hero picks for you when the sim lands, and the per-scenario picker.
Build & Sim
Build the pool and simulate it in one pass with the Build & Sim mode and the Sim tab in Build Settings.
Post-sim tools
Narrow and trim a simulated pool with FilterIQ and Trash, override a contest with the band picker, then hand the lineups to Fill and Swap.
