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 Grosvenor Casinos players aged 18 or over only. To claim, players must select the welcome offer in the cashier before making their first deposit of at least £20 (minimum deposit to receive the full bonus is £20). Deposits made via Paysafecard or PayPal do not qualify. Upon depositing, players receive a £40 bonus credited instantly to their bonus balance, plus 100 free spins on Big Bass Splash (each spin valued at £0.10). By claiming this offer, the player is no longer eligible for any other welcome offer on grosvenorcasinos.com. The qualifying deposit (£20) plus the bonus (£40) must be wagered ten times (10×) — total wagering requirement = £600 — before any winnings from the bonus balance may be withdrawn. The bonus and any resulting winnings are valid for 30 days from the date the bonus is credited; if wagering requirements are not met within this period, the bonus and associated winnings are forfeited. Free spins and any winnings from free spins are valid for 7 days from receipt; any unused free spins or unmet wagering on free spin winnings expire after 7 days. The maximum amount that can be converted from the bonus balance to withdrawable cash is £2,000; the maximum conversion from free spin winnings is £100. The maximum permitted bet when wagering with bonus funds is £5 per spin/round on slots. Wagers placed using a combination of cash and bonus funds generate winnings credited proportionately to cash and bonus balances. If a player withdraws cash funds before meeting wagering requirements, any remaining bonus balance is forfeited. Minimal-risk wagering strategies (e.g. simultaneously betting Red and Black on Roulette) do not count towards wagering requirements; players found using such tactics risk forfeiture of the bonus and all associated winnings. The promotion runs until further notice. Grosvenor Casinos reserves the right to withdraw or amend this offer at any time. Full terms and conditions apply. 18+. BeGambleAware.org.
