Review of GR88 Casino

GR88 Casino is an oddly named casino that was presumably chosen because the 3-letter domain with only one 8 in it was already taken. Their live chat folks told me that it is supposed to be simply pronounced "Great" rather than "Great-8" or spelled out "G-R-88". Anyway, this is one of many browser-based casinos running on Microgaming's Quickfire platform. It is licensed out of Curacao, and offers both casino games and a sportsbetting site. I deposited my money and took GR88 for a spin to see how it stacks up against its many similar competitors.

Software and games at GR88

As mentioned above, GR88 Casino runs off the hugely popular Microgaming Quickfire platform. This in-browser software grants you games from Microgaming itself, including popular slots like Terminator 2, Immortal Romance, The Dark Knight, and the massive progressive Mega Moolah. Microgaming also has deals with third party suppliers that allow you to play their games as well, games such as 300 Shields from NextGen or MegaDeth from Leander Games. In addition the casino has games from the studios of Play'n Go, which was a nice surprise.

Having said that, one of the first things that you will notice is that the number of games available is not as big as you find at many similar casinos. GR88 appears to have hand picked games and the full Quickfire catalogue is not available here. There are 48 video slots in total, 20 table games, 8 video poker games plus an assortment of other classic slots and parlour games. Whether or not this will bother you I guess is all down to whether they carry your favourite games or not.

The table games at GR88 are supplied by both Microgaming and Play'n Go. There are versions of Craps, Blackjack, Baccarat, Casino Hold'em, Caribbean Stud, Roulette, Pai Gow Poker, and a mystery game called "Beat Me" which I found out was Play'n Go's name for Casino War. Video Poker players likewise have a choice of 5 or 6 variations.

Support and banking options

Customer support at GR88 is provided 24/7 via either email or live chat. The live chat operators are not available at all hours of the day, but from what I saw they tended to be available during European daytime and evening hours. When available, I never waited more than a minute for an operator to respond, and I was impressed by the level of service provided, even as they sat there answering my inane questions about why the site was named like it was and how to pronounce GR88.

Transacting with GR88 is relatively painless because of the vast number of deposit methods accepted by the casino. In addition to your usual credit and debit cards, and common e-wallets, the site also supports numerous local direct bank transfer methods such as iDeal, POLi, Boleto, Sofort, and LobaNet, that will be convenient for people in many different countries. Withdrawal options are also plentiful and my test withdrawal to a Skrill account was received in under 48 hours which is not too bad.

Withdrawals are where I ran into my main beef with a casino that I was, up until now, quite impressed with. Apart from the small €2500 per week withdrawal limit, in the fine print of the T&Cs you will also find a stinker lurking that is going to hurt big winners or those of you that like to deposit, play, and withdraw over the weekend for example. Only the first withdrawal each month at GR88 is free of fees. After that, your 2nd withdrawal will cost you a 5% fee, and your third will cost you €100. Consider the scenario where you win €10,000 and now must withdraw €2500 per week over a month - that privilege will cost you a princely €325 in withdrawal fees. It also means that if 5% of your withdrawal is greater than €100 (i.e. you are withdrawing more than €2000) and you can't wait until next month, you would be better off submitting a minimum withdrawal as your second for the month, then making the big withdrawal your third for the month. These fees go far beyond the cost of handling the withdrawals and look to me to be nothing more than an attempt to discourage people from withdrawing regularly. It is an unusual cost to bear for those customers that casinos usually love the most: the frequently playing regulars.

Security and fairness

As you would expect of any competent internet casino, all of your gameplay, transactions, and communication with the GR88 Casino servers are encrypted using standard 128 bit SSL encryption. However the most pleasing thing in terms of security was the site's guarantee that customer funds are ring-fenced from the operational funds of the casino. This is supposed to ensure that should the casino ever be mis-managed or go out of business, customer funds remain untouched and available for withdrawal. This is an excellent practice that all online casinos should adhere to, but sadly few do.

In terms of game fairness and transparency, all games supplied by Microgaming are independently tested and certified by iTech Labs to provide random results and payout rates that match the theoretical RTP numbers for the games. Speaking of which, GR88 has a helpful "Game RTPs" page that lists the RTP numbers for the vast majority of its games.


Good games, solid support, the option of also betting on sports, and a guarantee that player funds are segregated from operational funds are all highlights for GR88 Casino. However the issues with the fees charged by the withdrawal department and the low weekly withdrawal limits that may force you to withdraw multiple times in a month are major and detract from what is an otherwise good casino.

GR88 casino is a place I discovered a while ago. I was given a 10€ free chip as a new member and I remember I played Game of Thrones slot and I managed to clear almost half of the bonus but at the end I lost all. For a while they sent me lots of spam mails and then they stopped. I never made any deposit there because I kept reading many bad comments from players who didn't get paid so it made me quite cautious. However, after reading some decent reviews here I might consider making a deposit, as they have very nice selection of games and the time I contacted support they acted in a professional manner.

an casino where i still don't understand anything from. i have receive multiple no deposit bonuses or spins from them, without asking for it. never won enough to request a withdrawal, but atleast i had fun with those bonuses. there site is not so big, but there design is awesome, cashier works easy and good, deposit options they have enough, support is not always online bit sad! and promotion's are really good sometimes even got 500% deposit bonus, or lot of free spins on small deposit, great rewarding! but now starts bad story here, i received once a code for free bonus from them, didn't work so asked the chat , and they didn't checked it they blocked my account directly, then i discussed with them about it, and they tell me i'm abusing there bonuses, i was shocked i told them you are the one who sending me different free bonus, and no where i could find that i was not eligible to claim all of them, well i knew this would be an endless discussion, and decided to leave it with this, since i didn't lost any real money luckely;) well for me gr88 is history and never will be coming back.

finally an interesting one! I amost began thinking that there really remained only casino rewards casinos, but it isnt.
This casino is interesting by many things - at first by its title for sure 😂 50 shades of GR88 was the email subject I was really surprised by, in my email box.
The games variety is not enough, I would certainly add some NetEnts, but it is acceptable.
Another big! negative for me is, that this casino does not offer any no deposit promotion to my country (dunno if even to someone but heard something) and I am then scared about if there arent any hidden restrictions among another (deposit) promotions to me. Simply I dont like that feeling of being restricted in any way 😂
Overall impression is good, as there are may negatives, but I am glad that there are original ones like this 😂

GR88 casino i tried couple of time, probably few months ago i made my first deposit in this place. What i can say about my experience. Portfolio of games from quickfire is always good for any online casino, so i can't say that i did not have enough games to play, even if casino remove all games and left only 243 lines games and league of fortunes, for me it will be enough games selection and i will play in this casino and more important that i am will be happy. Bonuses and promotions are ok, i can't say that this casino do miracles with their bonuses and i never saw bonuses like this in any other casino, but bonuses ok, and this is good factor for casino. Customer support i did not touch at all, luckily i do not have any problems, and all questions are answered on website, for me it was not hard to find it. What i can say regarding withdrawals - i have one withdrawal from GR88 casino, no documents were requested for me, and i get paid on next day, this is something what i like. It looks like GR88 good and interesting online casino.

Gr88 casino it is nothing interesting for me casino, i played couple of times till i have win, and after getting paid i never make deposit in this casino. I'll start from pluses for this casino.
+ Software. It is regular microgaming quickfire games, but it works good, and i for all time that i played in this casino do not experience any slow spins or errors, even at guts casino such things sometimes happen with me, but never at gr88 casino.
+ Withdrawals and KYC. It was to my surprise very easy. One day to get verified all my documents(my utility bill payment was too old, and i was need to send another, if everything ok KYC should be faster), and one more day for withdrawal, no any problems here.
And now minuses for this casino.
- Bonuses and promotions. No any interesting promotions, reload bonuses is rare, so please do not wait anything really good from casino in that point.
- Customer support. I am not sure, but live chat most time when i play was offline, and it was hard to get help.
Final mark.
I do not like this casino, but my withdrawal was easy, and it is should be safe casino.

Oh, i remember good my first experience with gr 88 casino. It was a time when i was active no deposits player, and generally take every NDB i was able to find. One guy on russian forum posted a link and a code to no deposit bonus in this casino, so of course i was one of the first who take it 🙂 It was 88$ no deposit(gr88 and 88$ in no deposit bonus, sounds nice). But max payout for this bonus was only 50$, but still it is not so bad money, specially if it comes for free and as plus you get some playtime and fun. I played Gamesys games(or it is name Game OS, i really not sure, but the game name was china mega wild i think). Game is extremely low variance without any feature, but after about of two hours spinning only this slot i clear bonus. I speak with live chat and it was not need to make deposit in order to withdraw NDB, and i think this is really great thing. Casino ask for ID and utility bill, and i was really surprised that verification take for their cashiers only few hours, and moreover i was almost in shock when my cashout was paid in webmoney account within few hours. I try this casino once again when they add microgaming games, with a bonus, but without luck unfortunately. I think it is good place, or at least it was great place.

Gr88 casino it is microgaming casino and i try it few times only about half a year or so back and i really think it is not bad casino. Sick thing that casino did not allow to download software on personal computer because when i played with this casino for a first time i have some nasty lags and slow spins but live chat told me that this is not their mistake it is microgaming doing some things on server and therefore i have this lags. My other playing in this casino was good and i not have any lags. Live chat by the way is good and friendly i never can say that i was threated bad or something like this but i did not know if this live chat is 24/7 or not so sorry about it. Bonuses is average for microgaming casino without anything unique and probably it is a reason why i played only few times in this casino. I not was able to make payout request and see how it goes because i have no luck in slots in this casino mostly was lost in immortal romance slot but of course it is can not mean that casino is bad or cheated no i trust microgaming games. I think gr88 good and safe but i not try payouts.
