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.

New players only. Minimum first deposit of £20 required (PayPal and Paysafe excluded). Players must select the offer in the cashier at the point of deposit. A £40 bonus and 100 free spins on Big Bass Splash are credited upon qualifying deposit. The bonus can only be used on selected games. The qualifying deposit (£20) plus the bonus (£40) must be wagered 10× before any bonus-balance winnings may be withdrawn — total wagering requirement £600 ((£20 + £40) × 10). If an active cash balance exists, wagers are deducted from that first, then from the bonus balance. Maximum winnings convertible from the bonus balance is £2,000. Wagering contributions vary by game; minimal-risk wagering (e.g. simultaneously betting Red and Black on Roulette) does not count. Players have 30 days from the date the bonus is credited to fulfil all wagering requirements; any unmet bonus balance is forfeited at expiry. Withdrawing cash-balance funds before wagering requirements are met will forfeit the entire bonus balance. Claiming this offer makes the player ineligible for any other welcome offer on grosvenorcasinos.com. No bonus code required. Poker side games and Sportsbook bets do not contribute to wagering. Grosvenor Casinos reserves the right to withdraw or amend this offer at any time. 18+. Please gamble responsibly — GambleAware.org.

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 fair

Common restrictive clauses apply (cap on bonus winnings, restricted / excluded games) — standard for the UK market, flagged here for transparency.

  • moderateCap on bonus winnings
    Maximum winnings convertible from the bonus balance is £2,000.

    A cap limits how much you can actually withdraw from bonus winnings, however much you win.

  • minorRestricted / excluded games
    Poker side games and Sportsbook bets do not contribute to wagering.

    Some games are excluded from wagering or contribute less, so they clear the bonus slowly or not at all.
