BankrollSZN is a free daily fantasy sports and betting toolkit that runs real models instead of reselling someone else's numbers.
It covers six sports. Every one gets its own projection engine, its own lineup optimizer and its own daily data pipeline. MLB goes deepest: home run probability, park factors, ballpark weather, pitcher matchups, bullpen usage, stolen bases, Elo ratings and Monte Carlo game sims.
Most sites hide the model. BankrollSZN publishes a Model Weights page for each sport that shows what every input contributes, and it grades its own projections against real results every night. If a model stops working, the scoreboard says so in public.
The core tools are free with no card and no trial clock.
