Game Weighting Calculator
The UKGC capped wagering at 10x in January 2026. That headline number hides a critical variable: game weighting. If your preferred slot contributes 25% toward wagering, the effective requirement is 40x — identical to the pre-cap era. This calculator shows the exact cost in pounds.

Methodology
Effective wagering = advertised multiplier / game weighting percentage. A 10x requirement at 25% game weighting produces an effective 40x requirement.
Total stake required = win amount × effective wagering multiplier. This is the total amount you must wager before the bonus converts to withdrawable cash.
House edge cost = total stake × 3%. We use 3% as a representative house edge for UK online slots. Actual RTP varies by game (typically 94%–97%), so your real cost may be higher or lower.
Expected amount kept = original win amount − house edge cost. This is the statistical average — individual sessions will vary due to variance, but over thousands of spins this figure converges.
Cash spins comparison uses 0x wagering. With zero wagering, game weighting is mathematically irrelevant (0 × anything = 0), so you keep 100% of your win amount.
