Backtest your betting system on a season of real racing.

Rebuild the scoring model with sliders

Every one of the 15 signals in the scoring system becomes a slider, from off to triple weight. Think jockey form is noise? Kill it. Convinced market moves are everything? Double them. The pick in every settled race is recomputed with your weights on the spot, and the scoreboard shows your win rate, place rate and yield against the standard model - win rate swing and yield swing included.

Filter to the racing you actually bet

Run your model on everything, or slice it down: race type (Flat, hurdle, chase), going, field size, price band, score threshold, any date range. The simulator recomputes instantly, so you can watch an edge appear - or evaporate - as you tighten the rules. A slice you like can be saved as a bracket in one tap: it becomes your picks, drives your alerts and, on Max, is a strategy the bot can bet - and the search can even hunt the strongest scoring-and-filter combination for you.

Every bet type, priced honestly

Singles, doubles, trebles and four-folds in any mix (all four is the classic Lucky 15) at once: the simulator settles each day’s qualifying picks at Betfair SP after commission and reports yield as profit on turnover. No cherry-picked streaks, no “what if you’d started on the good Tuesday” - the whole record, every time.

From simulation to automation

Found a setting that hits harder? On Max your weights stop being a what-if: apply them as your own model, and the automation tools will carry out your rules on your own Betfair account. You set the system, you own the results. See what each plan includes.

Past performance never guarantees future results - the simulator exists to test ideas, not to promise profits. 18+, please gamble responsibly.
