# Grosvenor Casinos Bonuses & Offers

New players at Grosvenor who deposit £20 receive a £40 casino bonus plus 100 free spins on Big Bass Splash. The offer applies automatically, with no promo code required, and carries a 10x wagering requirement that sits well below the sector norm. The minimum qualifying deposit is £20. PayPal and Paysafecard deposits are excluded from this promotion. Two conversion caps apply: a maximum of £200 can be converted from bonus funds to cash, and free-spins winnings are capped separately at £100, so the practical ceiling is lower than the headline bonus suggests.
