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.
Open to new Grosvenor Casinos players aged 18+ who can view the offer in the 'Promos' section of their account. Promotion runs until further notice. Not available to players who open a new account and make their first deposit via PayPal or Paysafe. Select the offer in the cashier, then make a minimum first deposit of £20 to receive a £40 bonus credited instantly to the bonus balance, plus 100 free spins on Big Bass Splash. Claiming this offer renders the player ineligible for any other welcome offer on grosvenorcasinos.com. The £40 bonus may only be used on selected games; some titles are excluded and do not contribute to wagering requirements. The qualifying deposit (£20) plus the bonus (£40) must be wagered ten times (10×) — total wagering requirement £600 — before any winnings can be withdrawn from the bonus balance. Players have 30 days from the date the bonus is credited to fulfil the wagering requirement; any unmet bonus balance is forfeited on expiry. Maximum amount convertible from bonus to cash is £200; maximum total win from the bonus is £2,000. Withdrawing any part of the cash balance before wagering requirements are met will cause the remaining bonus balance to be forfeited. Free spin winnings are credited as a bonus, subject to a separate 10× wagering requirement playable on Big Bass Splash only; players have 7 days to use the free spins before they expire; maximum win from free spin winnings is £100. Wagers placed on cash balance take priority over the bonus balance. Minimal-risk wagering strategies (e.g. betting Red and Black simultaneously on roulette) do not contribute to wagering and may result in forfeiture of the bonus and any associated winnings. General Grosvenor Casinos terms and conditions apply.

A fixed formula on this offer's verified terms — wagering (38%), value (26%), validity, min deposit & max bet — not an opinion. Always confirm the current terms with the operator before claiming.
Bonus terms — fairness check
Mostly fairCommon restrictive clauses apply (cap on bonus winnings, restricted / excluded games) — standard for the UK market, flagged here for transparency.
- moderateCap on bonus winnings
“maximum win from free spin winnings is £100.”
A cap limits how much you can actually withdraw from bonus winnings, however much you win.
- minorRestricted / excluded games
“some titles are excluded and do not contribute to wagering requirements.”
Some games are excluded from wagering or contribute less, so they clear the bonus slowly or not at all.
