Casino Summary
GRP Casino is very different from traditional sites because it is built almost entirely for mobile phones. It feels more like a modern video game than a standard betting site, with a clean design that is easy to tap and swipe through, and a gamified gambling experience. You will find yourself being rewarded for continued use and plenty of free spin offers will come your way via email.
The biggest “pro” is that their free spin bonuses pay out in real cash, so you keep what you win without complicated rules. However, the biggest “con” is that they charge a fee if you withdraw using PayPal, and the 5 day period for the welcome offer.
While GRP Casino shares the same high-quality platform as its sister brand Kwiff, it is strictly focussed on slots and casino games rather than sports betting. It is an enjoyable casino with regular profitable offers that have little to no wagering requirements at all.
One thing we LOVE about GRP is it’s daily rewards wheel. Unlike most other casinos that mostly just offer nothing or 1-3 free spins as a reward, GRP offers between 5-10 free spins on popular games that pay out nicely – with no wagering requirements. It’s a much better daily offer than any other casino we have seen so far, and your balance will rise considerably just by logging in daily.

Security, Fairness & Licensing
Licence Holder: Eaton Gate Gaming Limited
Sanctions/Fines: Yes. The operator paid a £480,305 settlement to the UK Gambling Commission in 2023 for past issues with checking player affordability and safety. This means they are now very strict with checking ID documents.
Data Protection: The site uses SSL encryption to keep your details safe, similar to online banking standards.
Fair Play: All games use a Random Number Generator (RNG) to ensure results are random. They are regulated by the UKGC, which demands fair play standards.
Regulatory History
The UK Gambling Commission (UKGC) imposed a £480,305 financial penalty on Eaton Gate Gaming Limited in December 2022 due to failings in Anti-Money Laundering (AML) and Social Responsibility (SR) procedures. The operator co-operated with the investigation, paid the penalty, and implemented corrective steps to adhere to regulatory requirements, ensuring customer safety.

GRP Casino Welcome Bonus & Promotions Breakdown
Note: All Welcome Bonus information is correct at time of publishing but liable to change due to the revolving nature of Casino welcome offers.
The Offer: Wager £20 on slots, Get up to 200 Cash Free Spins on Big Bass Splash.
Minimum Deposit: £10.
Wagering Requirements: Zero (x0). This is the headline feature. Any winnings generated from these spins are credited as cash, meaning you can withdraw them instantly.
Expiry: The spins are typically awarded in batches (e.g., 40 per day) over 5 days. You are required to wager £20 each day to unlock the subsequent batch.
Restricted Games: You must play slot games to qualify for the wagering target. Live Casino and Table Games generally do not contribute towards the £20 requirement.
Payment Exclusions: Deposits made via e-wallets (such as PayPal) or virtual cards are often excluded. Stick to a standard Debit Card for your initial deposit to be safe.
The Math: Cost vs. Value (Daily Breakdown)
This promotion offers Positive Expected Value (+EV), though it requires a bit of commitment over several days. Big Bass Splash is a fan-favourite for a reason, but it is a high volatility slot, so your daily results may swing significantly.
The Cost (The Daily Wager):
You must wager £20 per day on slots.
- Assumed RTP of Wagering Slot: 96% (e.g., Starburst or a similar low-variance game).
- Statistical Cost: $£20.00 \times 4\%$ (House Edge) $= £0.80$ theoretical loss per day.
The Reward (40 Free Spins per day):
- Game: Big Bass Splash.
- Value: 40 spins x £0.10 = £4.00 face value.
- RTP: Big Bass Splash is typically 96.71% (higher than average).
- Statistical Value: $£4.00 \times 96.71\% = £3.87$ cash value.
Net Profit (Per Day):
- £3.87 (Reward) – £0.80 (Cost) = +£3.07 Profit per day.
Total Net Profit (5 Days):
- +£15.35 Total Theoretical Profit.
Terms Analysis: The Pros, The Cons, and The Catch
The Good: “Wager-Free Winnings”
This is undoubtedly the strongest aspect of the bonus. If you land a massive catch on Big Bass Splash—potentially up to the 5,000x max win—you aren’t forced to re-wager it dozens of times. The money is yours.
The Bad: “The Commitment”
The structure forces you to return for 5 days in a row. The casino’s goal here is twofold:
- Habit Building: Encouraging you to make GRP Casino a daily habit.
- Variance: Over 5 days, there is a chance you might have a bad run on your qualifying wagers, which could eat into the profits from the free spins.
The Hidden: “The Win Cap”
Always check the fine print for a “Max Withdrawal” cap on the free spin winnings. While often generous (around £250), it does mean that hitting the absolute maximum jackpot on Big Bass Splash might result in some funds being capped, dampening the excitement of a 5,000x hit.
The Verdict & Strategy
Verdict: This is a solid offer for the “Grinder” player. It’s not a quick smash-and-grab, but the math is heavily in your favour. It suits a disciplined player who can stick to small, manageable daily targets.
Your Strategy:
- Deposit: £10 minimum (ensure you use a Debit Card).
- The Daily Wager: stick to a low-volatility slot to wager your £20 each day. Your aim is to complete the wagering with your balance intact, not to chase big wins here.
- The Reward: Play your 40 Big Bass Splash spins.
- Repeat: Maintain this routine for the full 5 days.
- Cash Out: Once the final spins are played, withdraw your total balance.
Note on the Game: Big Bass Splash is known for its High Volatility. You might have days where the fisherman catches nothing, and others where he reels in a huge multiplier. Trust the math to average out over the week.
GRP Casino Withdrawal Times (& PayPal Fees)
In our extensive testing (over 20 withdrawals), we found that GRP Casino operates on a very consistent, albeit slightly slower, schedule compared to its sister site Kwiff. While Kwiff often utilizes Visa Fast Funds for near-instant payouts, GRP Casino payments were consistently processed and deposited the afternoon following the withdrawal request.
While this isn’t quite as impressive as the sub-2-hour withdrawals at Kwiff, it is reliably “medium fast.” You can set your watch by it: request today, receive it tomorrow afternoon. As with Kwiff, the rare PayPal fee is still present.
| Method | Deposit Min | Withdrawal Min | Observed Withdrawal Speed | Fees |
| Visa Debit | £10 | £10 | Next Day (Afternoon) | Free |
| Mastercard | £10 | £10 | Next Day (Afternoon) | Free |
| PayPal | £10 | £30 | Next Day (Afternoon) | 1% Fee |
| Trustly | £10 | £10 | Next Day (Afternoon) | Free |
| Paysafecard | £10 | N/A | N/A (Deposit Only) | Free |
Weekend Cashouts: Yes, they process payments 7 days a week, so a Saturday request should arrive Sunday afternoon.
Pending Period: Unlike casinos that hold funds for days, GRP seems to batch process payments to release them the following afternoon.
GRP Casino Slots & Live Casino Selection
Total Games: Approximately 1,500+.
Key Software: The lobby is stocked by major developers including Play’n GO (creators of the Rich Wilde series), Pragmatic Play, NetEnt, and Evolution Gaming. As expected, the selection is identical to Kwiff.
Live Dealer Tables: Evolution Gaming powers the live environment. It shines on mobile devices, particularly with immersive Game Shows like Monopoly Live and Crazy Time.
Daily Jackpots: Absolutely. The site features the “Red Tiger Daily Drop” network, ensuring that specific jackpots pay out before a set deadline daily.
Interface & Navigation: GRP retains the unique “feed” style layout used by Kwiff. Instead of a traditional grid, games are presented in a swipeable list similar to a social media timeline. This is fantastic for phone users but can be cumbersome on a desktop if you want a quick overview.
Gaps in the Library: Because GRP Casino uses the same game aggregator as Kwiff, it shares the same blind spots. You won’t find the Blueprint Gaming classic Eye of Horus here, nor will you find specific high-RTP gems like 1429 Uncharted Seas or Book of 99.
GRP Casino Customer Support Waiting Times
Overall we would rate GRP Casino’s customer support highly; they are fast to respond and helpful. They don’t leave you waiting like a lot of other casinos for trivial help, and the casino’s website tends to be so stable that you rarely need to contact them in the first place.
- Live Chat: Available 24/7. You start with a “bot” that tries to answer simple questions, but you can get through to a human agent fairly quickly – we have never had to wait more than 5 minutes to be connected to a representative.
- Email Speed: Replies usually take 24-48 hours (help@grpcasino.com) – however during business hours they can be much quicker, replying within less than an hour at points.
Phone Support: No, there is no phone line for support. However given the speed of response on other support methods, this isn’t such an issue for us.
GRP Casino Frequently Asked Questions
Yes. GRP is fully licensed by the UK Gambling Commission (account number 44448). This is the same licence held by its well-known sister brand, Kwiff, meaning they must follow strict laws about protecting your money and ensuring games are fair.
It is reliable but not instant. In our testing, withdrawals were consistently processed and deposited the afternoon following the request (Next Day). While not as fast as “Visa Fast Funds” at some other sites, it is very consistent.
No, currently they do not have a no-deposit bonus for new players. You must deposit and play £20 to trigger the welcome free spins.
Yes, you can deposit with PayPal. However, be careful: GRP charges a 1% fee when you withdraw money back to PayPal, and the minimum withdrawal for PayPal is higher (£30) than other methods.
No there is currently no app for GRP as it is a new web only site. However seeing as Kwiff, their sister brand has an app we can likely see one developed in the coming years.
Yes! This is the best part of GRP. The free spins from the welcome offer have no “wagering requirements.” If you win £10 from your spins, that cash is yours to keep or withdraw immediately.
