Operator T&Cs snapshot
Captured by our editors at time of listing. Operators can change terms without notice — always verify on the live operator page before claiming.
This promotion is open to new players of Grosvenor Casinos aged 18 or over who can view it in the 'Promos' section of their account. To claim, players must select the offer in the cashier and make a minimum first deposit of £20 using an eligible payment method; deposits via PayPal or Paysafecard do not qualify. A £40 bonus is credited instantly to the bonus balance alongside 100 Free Spins on Big Bass Splash. The qualifying deposit (£20) plus the bonus (£40) must be wagered ten times (10×) before any winnings can be withdrawn from the bonus balance — total wagering required: £600. Winnings from Free Spins are also credited as a bonus and are subject to a 10× wagering requirement, playable on Big Bass Splash. If an active cash balance exists, all wagers are taken from that balance first, followed by the bonus balance. When a wager combines cash and bonus funds, any resulting winnings are credited proportionately to each balance. Cash in the cash balance may be withdrawn at any time. The maximum amount that can be converted from the bonus balance to cash is £2,000. The bonus is valid for 30 days from the date it is credited; any unwagered bonus balance is forfeited upon expiry. By claiming this offer, players become ineligible for any other welcome offer on grosvenorcasinos.com. There is one welcome offer per person. The promotion runs until further notice. Wagering contributions may vary by game. 18+. BeGambleAware.org. T&Cs apply.
