The William Hill welcome offer pays 200 free spins on Big Bass Splash. Activation runs through registration: sign up with the signup promotion, enter the offer promo code, opt in, then deposit £10 and stake £10 on Big Bass Splash within seven days of opting in. The spins credit at 10p each, £20 of play in total.
Three conditions shape the reward. Winnings are wagered 10x on Big Bass Splash, up to £30 converts to redeemable winnings, and the spins plus wagering must finish within 72 hours of the credit. The offer itself runs until 31 December 2026. The promo code field at sign-up is one of three activation routes in the claim-route guide.
Payment choice matters at qualification. Apple Pay, PayPal, Paysafe and the listed card prefixes sit outside the offer, so an eligible card deposit keeps the 200 spins in play. More deposit deals are grouped in sign-up bonuses.
