## Common Questions

**Q: What is DFS Simulator?**
A: DFS Simulator is a web-based daily fantasy sports lineup simulator and optimizer. It runs Monte Carlo and correlated simulations over a slate's player projections — up to 50,000 iterations per run — and builds optimized lineups exportable as DraftKings/FanDuel/Yahoo-formatted CSVs.

**Q: How much does DFS Simulator cost?**
A: Basic $19.99/month, Pro $49.99/month, Elite $99.99/month. Annual billing saves ~20% ($192/$480/$960 per year). No free tier. Billing runs through Stripe; cancel anytime.

**Q: Which sports does it cover?**
A: 21 sports: NBA, WNBA, NFL, MLB, NCAAB, CFB, CFL, UFL, EuroLeague, NHL, Soccer, Tennis, Golf, NASCAR, F1, MMA, League of Legends, Counter-Strike, Call of Duty, Dota 2, Valorant. Basic picks 1 sport, Pro picks 4 (switchable every 30 days), Elite gets all 24 with no cooldown.

**Q: Which DFS sites does it support?**
A: DraftKings (all plans), FanDuel (Pro and Elite), Yahoo (Elite). Each site's scoring system is encoded separately, so projections recalculate per site.

**Q: What simulation models does it offer?**
A: Four: quasi-random Monte Carlo (all plans), correlated multivariate Monte Carlo (Pro+), genetic search and bootstrap resampling from historical data (Elite).

**Q: Can users upload their own projections?**
A: Yes, on Elite — CSV projection upload layers the user's numbers over the base model with an audit trail. All plans support editing individual projections, locking/blocking players, and position overrides.

**Q: Is DFS Simulator a gambling site?**
A: No. It is a research and lineup-construction tool for daily fantasy sports contests. It takes no wagers and hosts no contests. DFS involves financial risk; the product is for users 18+/21+ where required by law.
