Other Important Grosvenor Sign-Up Offers Terms and Conditions
Grosvenor also runs regular offers for registered customers at the casino. Keep in mind that these promotions come with specific terms and conditions. This is why we’ve broken down the key details you need to know below.
Casino
New casino players at Grosvenor can get £40 when they deposit £20. Once newly registered customers sign up and deposit a minimum of £20, they will be eligible for a £20 bonus, bringing their total cash balance to £40 to play with. The bonus will be available on selected slots and live casino games. Note that deposits made with PayPal or PaysafeCard are not eligible for the offer. The bonus and the deposit amount will be subject to a 10x wagering requirement. Not all games contribute equally to the casino bonus wagering terms. Slots contribute 100% while live casino games contribute only 10%. Jackpots and progressive games contribute 50%. Once the bonus is received, players have 30 days to complete the rollover requirements. The maximum amount that can be converted from bonus to cash is £2,000.
Grosvenor Bonuses for Existing Customers
Grosvenor runs a good variety of ongoing offers, providing players with enough opportunities to boost their bankrolls. We have outlined the ones we think have the best value.
Best Odds Guaranteed
This is part of the exclusive offers at the Grosvenor sports betting section and is available for horse racing events. The offer will be eligible for existing customers after 9 a.m. on the day of the race. When the player bets on a horse and the starting price is higher, Grosvenor will pay out at the higher odds. The max bonus is £25K. The offer applies only to singles and multipliers.
Daily Free Spins
To take part in this promotion, registered customers have to log in and stake at least £10 on any slot to get 5 free spins daily. The bonus spins will be credited instantly to the player’s account. Note that once received, the spins will be valid on the following games: Eye of Horus, Jackpot King, The Goonies Quest for Treasure 2, and Wish Upon a Cashpot.
Grosvenor Responsible Gambling Tools
Grosvenor is a legit gambling site licensed by the UK Gambling Commission. Players’ safety is the operator’s top priority, and, therefore, it offers tools for self-exclusion to help players properly manage their gaming behaviour. Here are the options customers can use.
- Net Deposit Limits: Players can set net deposit limits directly from the cashier at Grosvenor.
- Reality Checks: These are a convenient way for players to keep track of the time they spend playing online.
- Take a Break: Players can set a break period of between 24 hours and 6 weeks. This will automatically lock access to their accounts.
- Self-Exclusion: This option allows gamblers to lock their accounts for a longer period – from 6 months to 5 years.
- Player Protection: An automated system that analyses and monitors players’ gambling behaviour.
Other Bookmaker Bonus Codes and Promotions
