I signed up on the site due to good reviews and easily deposited a few 100 USD which were all gone in lightning speed on small bets. Game payout was in the 50-60% consistent RTP range although I changed games a lot. Many games wouldnt load particularly those I wanted to play being Play N Go. Unfortunately although the site is in my language and caters to people from my country I have found out it is not legal to take bets from me but it seems that they ignore this.
What I have to stress positively is that when I contacted support and asked if it was safe to make a larger deposit they confirmed that it wouldnt be paid out easily. Therefore I saved myself more loss. Chances are they would have asked for KYC then said I am playing from a forbidden country and confiscated my wins and deposits. If I had lost they would have just kept deposits.
I then closed my account. Next day I got back to them and asked if I could withdraw the rakeback they advertise. But this is a scheme, it doesnt exist. They denied my request and said it is only for active players and cant be claimed by me and any funds on the account are gone. Also they asked me what I actually want in an aggressive tone. Give the fact that they actively encourage illegal gambling and take money they are not allowed to take they are very courageous and cocky to hardball players in such a way. You need balls of steel or you simply don´t care about players or you are planning an exit scam soon. Which could be, as I did not find that there is a lot of site traffic, few people in chat.
I from my end just said to myself no more good money after bad money but I feel people should know that Metaspins isnt a decent casino. There are a few triple A crypto sites around but Metaspins is not part of them. I really advise you to avoid this site as you will just be annoyed.

To make it short. Lucky Block is a rogue casino. This casino offers counterfeited slots. They offer the entire Novomatic games suite but these games are not from the original provider Gametube but from an ominous provider called "N2". My request to find out where this provider is located was not answered, on the contrary chat was closed and account locked.
Please open the requested games in fun mode and compare them to the originals and you will see that the game interface and menu is different to the original also colorwise. When checking the servers I was able to find out that this is not the original game server of Greentube.
A casino that offers pirated games cannot be trusted under any circumstances. Please stay away.

I signed up here due to generally favourable reviews and made the required deposit to become VIP instantly. This however never happened, so don´t waste your 500 USDT, it´s just a ploy.
I then tried about 60 games of which 30 didn´t load. Depending on the provider you are forced to submit personal details, pretty crappy for a crypto casino and that before you even got to withdrawal stage. My gameplay was abyssmal, doing many feature buys and playing 1 USD per spin, my best win was around 50 USD. More frequently I would buy a feature for 50 and get 5. After my money was gone with an RTP of under 50% I checked the VIP programm for bonuses and perks. I got a 10% cashback and they actually put 3xWR on this! How scummy, this is free cash on serious casino sites. Totally lame VIP program. I wanted to check the tournaments, but wasnt possible as the site always displayed error messages. After my measly cashback was also lost in record speed I decided I had had enough of this rubbish, there are just so many better sites. So I decided to go on live chat to close my account. It took me 20 minutes of playing with the worst peskiest chatbot on the planet called Alex to finally get an operator. I had to explain in detail why I wanted to close the account. At some point I said, I am 17 and a gambling addict. And you know what his response was? Do you want 40 freespins on some crap game with only 20 WR? I mean come on, what lowlife approach is this to responsible gaming? Well after I told him I wasnt into it we finally got the account closed. Next adventure will be to get my gameplay logs, still on that. All in all this casino made a very bad impression on me and I have the feeling it is not professionally run. Also I do not think they have solid financial backing and no strong player base. I would definitely worry if Ihad large amounts here. From what I read in the chat there have been non payment issues. What they seem to trick people with is the jurisdiction question. I for example am from a jurisdiction where gambling is not allowed in the form Bets.io offers. I advised them of this but you get the standard text that you are responsible to assure you are allowed to play from your location. Still they take your money, convenient for them. Then I read in the forums here of big winners who didnt get their money paid out suddenly because the casino uses the location against them. That´s totally unethical and fraudulent. So if you lose, they dont care were you are playing from, but if you win, they will use that as an excuse to terminate your account and confiscate your winnings. STAY AWAY FROM BETS.IO, this is a super rogue casino!!!
