GRP casino is operated by Kwiff Limited, a company owned by Eaton Gate Gaming, licensed and regulated within Great Britain under the UKGC. The same license covers two other brands, Kwiff and Slots King, making them the couple of sister brands to GRP casino.
Kwiff
Kwiff is the best known sister site to GRP casino which covers both casino games and sports betting. Yes, along with the thousands of slots and other casino options, one of the best features of Kwiff is the amazing sports betting section which covers plenty of thrilling markets with high value odds and wonderful betting features.
Including the chance to use bet builder, enjoy enhanced odds, claim £40 in free bets as a new player and bet on your favorite markets on mobile.
Slots King
Slot King is the other casino-first and foremost sister site to GRP casino. They've got plenty of exciting gaming options to show off with whereas the general experience is primarily the same, from the game library through the bonuses and up to the payment options and the responsible gambling tools like time‑outs and self‑exclusion.

GRP casino bonuses for new players and ongoing promotions for existing customers
There aren't many promo offers available at GRP casino and the main option you'll be provided with is the welcome bonus. Let's take a look.
Bet £20 to get up to 200 free spins with no wagering requirements
The welcome offer at GRP casino provides new customers with the chance to stake £20 on slots within a single day to claim 200 free spins on eligible games. Now, those are separated into five parts of 40 spins valued at 10p. In other words, you'll have to stake £20 a day on each of the first five days you're playing within the platform to claim the spins for the particular day.
Those are valid for Big Bass Splash and you can use them within 30 days. No wagering requirements on the winnings apply but max conversion limit is capped at £250 for the 200 spins. Full terms and conditions apply.
Ongoing promotions
Aside from the first deposit bonus, GRP casino doesn't feature any additional promotions at the time of writing this review. The alternative they provided me with was the chance to enter the Adventure Spin tournament on the Peter & Sons slots for a chance to get part of the £1,000 cash pot split between the first 50 players.
Top GRP casino games to play: Exciting slots, live tables and more gaming options
With plenty of slots and live tables, interesting RNG table games and some specialties, GRP online casino has a wide variety of gaming options to show off with.
Slot games and high payout jackpots
I had a rather entertaining time playing with the GRP casino slots. Those are supplied by the best game developers in the industry like Pragmatic Play, NetEnt, Play'n Go and so on, ensuring players have access to all of the best titles on the markets including:
- Big Bass Blast
- Big Bass Boxing Bonus Round
- Book of Dead
- Golden Winner Grand Chance
- Age of the Gods: God of Storms
- Poseidon Ancient Fortunes Megaways
- Gonzo's Quest Megaways
- Mental II
- Fishin' Bigger Pots of Gold
Many exciting jackpots are included within the GRP casino's game library, too, such as the progressive series of the Age of the Gods, WowPot, Big Bass Jackpot Bonanza, Mega Moolah, King Millions and several other options.
Table games and specialties
Some interesting RNG tables have been added to the casino section of GRP casino, too. I had a great time with their European Jackpot and 20p roulette but the overall variety is quite an astounishing one and goes much further from the couple of examples I showed you.
They include not only blackjack and roulette but also some exciting baccarat and sic bo titles, coupled with video poker like Jacks or Better, Aces and Eights and Casino Hold'Em.
Together with those, though, the site covers some crash games, also, like Red Baron, Diamond Trader, FlyX, Spaceman and Big Bass Crash.
Live casino tables
The live dealer section of GRP casino offers plenty of thrilling opportunities by Evolution, Playtech and Pragmatic Play, with various games to pick from such as:
- Monopoly Roulette
- Hippodrome Live Roulette
- Infinite Free Bet Blackjack
- Multiplayer Blackjack
- Speed Baccarat
- Always 9 Baccarat
I really enjoyed their poker games, too, which cover several Casino Hold'Em options, Caribbean Stud Poker, Ultimate Texas Hold'Em, Super Andar Bahar and Three Card Poker.
Interesting game shows aren't left behind and top titles like Adventures Beyond Wonderland, Color Game Bonanza and Ice Fishing can provide quite the enjoyable authentic experience with HD streaming and professional dealers.
All you need to know about GBP banking at GRP casino: Deposit and withdrawal options, withdrawal times and limits and KYC verification
UK customers won't have that many options to use for transactions to and from GRP casino. The deposit methods cover Apple Pay, Visa and Mastercard debit cards, as well as pay by bank. The best feature of it all is the fact you can use a Revolut debit card. Both the min deposit and the minimum withdrawal are £10 and no maximum withdrawal caps have been places.
Something I consider to be among the biggest advantages of GRP casino, though, is the fact you can cash your winnings out quite quickly. Sure, bank transfer takes a bit longer but on certain debit cards and if you're cashing out to the Revolut e‑wallet you'll be able to get your money out within 30 minutes.
The casino platform provides a high level of safety, using secure payment gateways and requiring you to go through the KYC identity check prior to first withdrawal, as per the UK standards.
Customer support at GRP casino: FAQ section, live chat and more
The support service provided at GRP casino is a relatively good one. I was offered to check out the Help Centre which had some basic FAQ answered on payment methods, how to verify my account, what to do in case of technical issues and so on.
But in addition to that the casino's team responds on live chat and email, too, at [email protected]. The fastest option is, of course, the live chat which is accessible directly via the website.
They don't work 24/7, though, and if you need assistance, you can get in touch with the live chat team from 9 AM till 1 AM Mondays through Sundays.
GRP mobile experience: Playing with GRP casino through the iOS and Android mobile app
If you feel like playing on your favorite games while you're on the go, you can easily do so with the GRP casino mobile site. You just open the page on your phone's browser and that's it. The site will load instantly both on Android and iOS devices ensuring tap-friendly access to all the features it presents you with on desktop.
There's no native app but the platform utilizes a progressive web app which means you can set up a shortcut on your homescreen which leads directly to the site and allows you to access your favorite titles with one tap only.
Player reviews and is GRP casino legit
GRP casino is a completely legitimate gambling platform. The site is licensed by the UK Gambling Commission under account number 44448 (with remote operating license 044448-R-323408 017). It's managed to gather plenty of positive player reviews, especially in terms of the withdrawal speed.
Probably the biggest drawbacks are the smallish bonus selection and the fact the live chat isn't 24/7 but in terms of payout processing, fair play and game quality and variety GRP casino is among the best in the industry.
Safer gambling with GRP casino
Being under the regulation of the United Kingdom Gambling Commission, GRP casino places quite a big emphasis on responsible gambling. They've got various resources which you can read through to learn more about how to play within limits, together with a self-questionairre to make use of.
You can also employ some responsible gambling controls such as deposit limits, reality checks and self‑exclusion. Blocking your access to GRP casino, its sister sites and all the other UKGC casino and betting brands is also possible through the GamStop self-exclusion scheme.
Final thoughts on GRP casino and its sister sites
GRP casino is a wonderful UK-licensed, mobile compatible casino brand which has plenty of exciting features to show off with, from the great game library up to the quick withdrawal processing. And if you feel like betting on sports, you can easily do so with one of their top sister sites, Kwiff, which is also among the best sportsbook in the UK.
