Grosvenor Casinos bonus code — October 2026

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 The qualifying deposit (£20) plus the bonus (£40) must be wagered ten times (10×) before any winnings can be withdrawn from the bonus balance — total wagering required: £600.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 Cash in the cash balance may be withdrawn at any time.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.

This promotion is open to new players of Grosvenor Casinos aged 18 years and over who are fully verified and can view the offer in the 'Promos' section of their account. Only one welcome offer is permitted per person. The promotion runs until further notice and is managed by Grosvenor Casinos. To be eligible, players must select the offer in the cashier and make a minimum first deposit of £20; deposits made via PayPal or Paysafecard do not qualify. Upon making a qualifying deposit of £20, players receive a £40 bonus credited instantly to their bonus balance, giving £60 to play with in total. Players also receive 100 free spins to use 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 The qualifying deposit (£20) plus the bonus (£40) must be wagered ten times (10×) before any winnings can be withdrawn from the bonus balance; the total wagering requirement is therefore £600 ((£20 + £40) × 10). Free spin winnings are credited as bonus funds and are subject to a separate 10× wagering requirement, playable on Big Bass Splash, with a maximum cash conversion cap of £100 from free spin winnings. The maximum win from the bonus funds is capped at £200. Wagering contributions vary by game type: Slots contribute 100%, Live Casino games (including game shows) contribute 10%, and Jackpot and Progressive games contribute 50%. All wagering requirements must be fulfilled within 30 days of the bonus being credited; any remaining bonus balance is forfeited after this period. If you have an active cash balance, all wagers are taken from the cash balance first, followed by the bonus balance. When a wager uses a combination of cash and bonus funds, winnings are credited proportionately to each balance. Cash balances may be withdrawn at any time. By claiming this offer, players are no longer eligible for any other welcome offer on grosvenorcasinos.com. Grosvenor Casinos reserves the right to withdraw or amend this promotion at any time. 18+.
