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 years and over only. To be eligible, players must select the welcome offer in the cashier and make a minimum first deposit of £20 (deposits via PayPal or Paysafecard are excluded). Upon qualifying, players receive a £40 bonus credited to their bonus balance plus 100 free spins on Big Bass Splash. The free spins are exclusive to Big Bass Splash; players must launch the game to receive the spins, have 24 hours to click 'claim', and once claimed must use the spins within 7 days or they expire. Each free spin has a value of £0.10. The £40 bonus (and the £20 qualifying deposit) must each be wagered ten times (10×) before any winnings can be withdrawn from the bonus balance — total wagering requirement = £600 ((£20 + £40) × 10). The maximum amount that can be converted from bonus balance to withdrawable cash is £2,000. Players have 30 days from the date the bonus is credited to their account to meet the wagering requirements; unused bonus funds are forfeited on expiry. The bonus can only be used on a selection of eligible slot games; wagering contributions vary by game. If a player holds an active cash balance, all wagers will be deducted from the cash balance first, followed by the bonus balance. Withdrawing cash funds prior to completing wagering will result in forfeiture of the bonus balance. Claiming this offer makes the player ineligible for any other Grosvenor Casinos welcome offer. No promotion code is required. Minimal-risk wagering strategies (e.g. simultaneously betting Red and Black on roulette) will not count towards wagering requirements; Grosvenor Casinos reserves the right to forfeit bonuses and associated winnings where abuse or fraud is identified. The promotion runs until further notice. This promotion is subject to Grosvenor Casinos' General Terms and Conditions. 18+. Please gamble responsibly.
