18+ only. BeGambleAware.org. Slots are designed to lose money over time. Set deposit and time limits. Bonus EV figures use the formula bonus − (wagering × bonus × 4% house edge) — see each operator page or our methodology for per-operator EV. Always read each operator's full T&Cs.

How We Calculate Bonus EV

Genuine EV = Bonus − (Wagering multiplier × Bonus × 4% house edge)

The 4% figure represents the typical house edge across UK slot RTPs. The formula gives the genuine retained value of each bonus after the wagering requirement is accounted for. The UKGC caps wagering at 10x as of April 2023 — every operator in our comparison complies. Read the full methodology or our wagering guide for worked examples.
