Backtest your scoring 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 and drives your alerts - 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 what-if to your own model

Found a setting that hits harder? On Max your weights stop being a what-if: apply them as your own scoring model and every racecard, result, daily email and win alert is scored your way. Save the filter combinations that worked as brackets, and your picks follow those instead of the house ones. 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.
