Blacklisted

AskGamblers have been notified that 4Grinz casino is operating without a valid licence issued by a regulated authority. As a result we issued an official warning hoping that the operator will manage to solve the issue. Unfortunately, months afterwards, the casino is still operating without a valid licence which basically means zero protection for players in case of a problem with the operator and that is why 4Grinz is now being added to our blacklist.

4Grinz Casino - Account wrongly disabled and winnings seized although I followed Customer Service's instructions
After doing my research on the various BTC casinos, I joined 4Grinz while brand new to BTC and new to every aspect of that, and their Customer Service team misled and manipulated my trust. When I first joined, CS informed me that my deposit was still waiting on its 7 confirmations. I explicitly asked what I should do and was told, "Just keep playing and hope it gets confirmed," which is verifiable, and which CS Lee reconfirmed that he had told me. I asked if there was anything I could do to speed up the confirmation, and he said "some people do know how to make it go faster... :)", whatever that means. So, today, when I was waiting on confirmations, I followed this explicit advice and played. I won, but I waited until my deposits were confirmed to submit a withdrawal. I literally waited until after I had received email confirmations from 4Grinz that my deposits had been accepted. Only after I submitted my withdrawal request, did I receive the "fraud alert" email, which explicitly states "We have detected suspicious activity with your 4Grinz.com player account. An attempt was made to deposit funds in the amount of XXXX that resulted in zero confirmations and is suspected as double-spending." (The XXXX is what it actually says; it does not even say an amount). Again, I received this after I received the email confirmation of their acceptance of the deposit, also verifiable. You can see the emails and time stamps below (acceptance of deposits came at 2:25 AM; fraud alert stating deposits had 0 confirmations came at 3:15 am). You can also see that 4Grinz marked all four deposits as accepted more than an hour before I submitted my withdrawal request. Additionally, you can see my many deposits, because I have been a fiercely loyal customer since I joined. Now they have seized my funds and disabled my account. Lee said that this is "out of [his] hands," though he admits he did explicitly tell me to keep playing while waiting on confirmations. I asked to speak to a manager, who was not available.

4Grinz Casino - Ignoring its own Bitcoin Payment Provider, refusing to pay 6.775 bitcoin winnings since 10/11/2016
The Client's Name has been removed along with the email address used for safety reasons. Please feel free to contact the companies below to verify that they know the Client and have known him for a long time plus that the Client provided them with all neccessary data including ID & Transactions numbers from the day in question in order to be forthwith. These messages below are the best evidence that both tell the narative in a sense and share their conclusions after seperate and independent investigations and both have seperatly come to the same conclusion and that is that the Client did nothing wrong, the transactions are clean and The Client should be paid in full immediately. This event happened on 10/11/2016 the Casino that seized the 8.4 Bitcoin in winnings while The Client was still playing and locked him out of his account is 4GrinZ Bitcoin Casino . The last message on the bottom tells what happened took place best along with their recomendation regarding how to settle this. ‘Cubits’ is the Bitcoin Payment Provider for 4GrinZ Bitcoin Casino and ‘Yalet Bitcoin Wallet’ is the Mobile Bitcoin Wallet Application Provider used by The Client for nearly a year and ‘Scorechain’ is its sibling company that specializes in Blockchain security and investigations of various types of fraud, money laundering, etc that take place on the Blockchain. The companies are extremely qualified to express their conclusions from an independent standpoint. Thank you for this opportunity to attempt to right a wrong here. ================================================================================================== -------- Original Message -------- Subject: Re: You've been contacted by The Client Local Time: October 15, 2016 9:51 AM UTC Time: October 15, 2016 4:51 PM From: support@yallet Hi Client, Sorry for that. The fee part of the API was down. It should now work as expected but you should always check if fees are OK for you use-case.

As we said we claim that your transactions are clean. There are few parties in between 4Grinz and Cubits, we are discussing your case.

We also have a company called Scorechain that is rating Bitcoin services depending on how they comply with usual regulatory requirements and how they treat incidents with their customers. We were contacted by one of our user who lost significant amount of bitcoins because his transaction from our wallet to your casino didn't confirm for 3 hours and you said it was fraud. 3 hours confirmation is usual in Bitcoin-world, especially those times where the blocks are pretty full! Moreover, the fees at this time were so high that we had a problem with our Yallet API, even blockchain.info was down at that time. All of our users were affected and were sending transactions with not enough fees at this time. The Client was one of them. All has been fixed few hours later but the evil was done. At the end, you got the money and there was no fraud and no double spend recorded in the blockchain. Can you please consider this exceptional situation and refund The Client with the Bitcoins he should have get from your casino? (around ~6-8 BTC / $4200, you should have the exact value) He seems to have been a great customer spending more than 89 BTC on your site. It will be a very appreciated move. Best regards, The Yallet/Scorechain team

Top reviews from our players

I like 4 grinz support staff. Very friendly and supportive. Always there to help when I'm in need. Especially LEE and SANDY been very helpful.....

There games are upgraded now, more to come.....

Bonuses are very cool and fair... coinback is my fave...

Easy and quick payouts....and they have spins for every deposit if on promotional days which is a lot...

Match bonuses on promo days.... and many level and points to become a loyal vipplayer and etc...

Overall they are on my top 5 bitcoin casino.....

Pretty much nothing, before they had no reload bonuses for months I was disappointed, but once when I heard about the changes I was happy to see my chatty friends again......

Vnqueen, you are far too kind, :) Say hello to the hubby! Cheers Team 4Grinz

Live Chat Support is friendly and informative
Coin Back and Deposit Back are great Bonuses without wagering requirements
All the best games from top Providers
Platform is easy to use

Mobile website could be more user friendly for accessing information, but gaming is wonderful.

And we are happy you take advantage of everything we have to give :) Lets talk some more about our ways to improve. See you at the games! Team 4Grinz

Friendly staff.I'm a fan of the no bs bonuses, and real cash back.
Love the site, it's clean and setup well.

I've only played here a few times, and it was a little while back, but I enjoyed it. Very professional and well run site.

I was disappointed to go back recently to play some of my favorite games and see that they had gotten rid of my game art games!

Bring them back!:( It's so hard to find them as a U.S. player.

That's the only downside though.

You're so right Donkeyramp. GameArt is a player favorite and we miss them too. Our new platform provider has an agreement with them, but it's taking forever for GameArt to sort this one out. Thanks for the kind review and we'll keep you posted on new games as they're added to our library.

4Grinz Casino is a rare gem among not only Bitcoin casinos but online casinos in general. The marketing is genius to say the least. Every week a player receives a percentage of Coinback" and "Deposit back" to play or withdraw. No drawn out bonuses that require a player to jump through hoops with playthroughs, withdrawal documentation and a long and drawn out wait to receive your winnings.

4Grinz is straight forward without all the "fluff" of other casinos. I make my deposit, play my favorite slots and if I win, the cash out process is a breeze. I usually relieve my winnings to my bitcoin wallet within 30 minutes. I'm a happy camper.....keep up the good work!

Hmm, let me mull this over..... No dislikes whatsoever!

Thanks so much TinaTech and we're thrilled to know you're happy with Coin Back and Deposit Back! We sincerely appreciate the review too and know we're lucky to have a loyal player like you. Plus, you're right. Coin Back easy, automatic and ensures you never leave empty-handed. Win and withdraw immediately and, if you don't win, get a guaranteed return.

♤LEE♤ and ♡SANDY♡ are the management and all around wizards that to a no name casino in to 1 of the top 10 casinos in one of the most competitive gaming markets in the world (online) in under 1yr and I watched them do it.
They are brilliant, there ability to attract and retain customers is second to none and now with a % cash back policy every Thursday, it could be one of the fairest and or let's say the best way to maximize the value of your money. Without the hassle of haggling with support or bonus wagers requirements. Just a % back, depending on your level it could be from 10% to 50%. I think you can thank Lee and Sandy for the technical, Web, email, graphics and training the new customer support workers.

That believe it or not even though the have shot to the topthey did it so fast that I don't even think they are on profit yet. Meaning that while all of you get rich playing at 4grinz, they are putting there checks back in the business to buy more serves and develop new ways to handle the traffic but that's the burden before the bounty.
Keep up the great work.

-LGTHEGRIM

Wow.. I was left speechless, thank you. Funny thing is we were just talking about you, and then we got this. Talk to you soon amigo. Lee

I'd like to share my positive experience playing at 4Grinz. I'm playing there for a long time and I love sort of games & support that is always helpful ( only missing NetEnt but it's reasonable to haven't them on board) . 4Grinz is definitely best bitcoin casino on board!

Thanks so much Burneas. I must say, your suggestions as to how we should launch our VIP promotions was spot on and I'm glad you got to take the first VIP 25x10 for a test drive. We look forward to a long and lasting relationship with you and our players. You make it all worthwhile. :)

About 2 hours ago i wrote a lengthy review on my experiences at 4Grinz, after picking through my brain and recollecting all the nice times i have had there over the past few weeks, I decided to go make a deposit of .250 (250mBtc). less than two hours after writing that review I just hit for a high of 5.1 BTC... unbelievable.. that's the most I have ever won to date. I most likely wouldn't have made a deposit at this time of morning had i not been perusing through ASKGAMBLERS. Today is going to be one hell of a good day, Thanks to AskGamblers and the red hot 4Grinz Casino. Get down there quick ladies and gents, they're just handing out money today, so it seems. For the record, I hit 2.2 BTC on Gameart's Power Dragon, and cleaned up with another 2.9 BTC on Booming Games' Master of the Sky. Think i may have found a new favorite game, that bonus round......is lethal.. Thanks 4Grinz. :)

Thank you again Alexd21 and congratulations on achieving VIP status. You've been loyal to us since the beginning and helped us develop along the way. We celebrate your good fortune (though Lee will be eating cold pizza for a while). :)

By now, I'm sure that you've heard many great things about 4grinz but I want to share a nice experience I had at 4grinz earlier. I have been doing online gaming for over 15 yrs now, played at so many casinos, to many to count. And honestly in my opinion most online casino are pretty much all the same. You log in, deposit and play.

If available ive chat support is there if there's any issues or concerns. Ok now, today I was have a very bad day and wasn't feeling to good but i still logged onto 4grinz and ended up on live chat for some apparent reason I cant recall, for the first time in 15 years, a CS at 4grinz (Lee) instead of trying to get me to deposit, he wanted me to go rest and feel better. It's the little thing like that goes a long way.

4grinz, everything you want in a casino and more! Expect the unexpected!

Thank you Hoa for the generous review. You bring up a very good point. Here at 4Grinz, we believe that playing at our Bitcoin Casino should be an entertainment experience, and it's important to us that your visit is a pleasant one. Just like any casino, live or online, in Las Vegas or from the comfort of your own home, you should feel welcome and appreciated. We get that and we're glad you do too. See you at the games!

Well here's a review I have been waiting to write for quite some time now. It's a very welcoming site to see 4Grinz casino finally added to the AskGamblres network.

With that said, I have been playing at 4Grinz for a couple months now and the place just keeps getting nicer and nicer; more games, more bonuses, more perks. It has a very warm and family like feel to it, one which isn't really duplicated anywhere else, in my experience. The Staff there is wonderful, probably the best in the industry, that i have dealt with. I tend to be somewhat of a demanding player, and I often make a fair amount of specific requests, the support staff there are always willing to go over and above to ensure that I'm a satisfied player, which can be a daunting task at times, but they really do go out of their way and that's one of the reasons I continue to come back.

As far as the games there they offer some top name software that are commonplace all the way down to some lesser known games that you probably haven't played before. If you're into 3-D graphics with the hi-tech bonus rounds; they have that, and if grandma wants to give it a shot at her luck, they have some traditional 3 reel classics as well. My personal favorites however, are the video slots by Gameart. Titles like Dragon King, Ancient Gong, and Power Dragon, just to name a few. These are presumably Japanese games and they do not leave anything on the table.

They must have a very high RTP rate because almost every time i go, one of these GameArt's is just start shooting bitcoin at me faster than i can fill my wallet. They have a top of line Live Dealer Casino as well if you're into the live action. The payouts are always instant, and I can definitely attest to that because they are cashing me out more often than anywhere else I play, and that's the honest truth. Besides the cool games, and perks, and support, what it comes down to for me, is winning, and I do quite well there. If you're considering stopping by, I would definitely recommend that you do, and right now is a great time bc they just rolled out a new loyalty program and they're handing out mBTC left and right. Sometimes I'll stop in and there's micro-bitcoins that have just seemingly appeared in my account. Whether from the loyalty program or the very generous affiliate payouts, you definitely get your money's worth, and then some. Its top 3 casino for me and I would say its my personal favorite overall, and I'm a member of least 40 other casinos so its not my first day at the park.

I'm not sure where they came up with that current 6.63 rating, that's woefully inaccurate in my view, it should be much higher than that and I think it will be as more and more reviews come in. Give them a shot, go win yourself some bitcoin, you wont be disappointed.

Alexd21, we can't thank you enough for the warm welcome here at AskGamblers. You're a loyal player and one of the first to join the 4Grinz family. Alexd21 has also helped us develop the new 4Grinz rewards program, and he continues to provide great feedback. It's a pleasure serving you! See you at the games! 4Grinz Staff
