Things here are super slow

Things here are super slow. The withdraw limit is set to 500 euro and you wait more than a week just for one withdraw to be approved, this of course is done on purpose. AVOID

I'm more into classic casino stuff

I'm more into classic casino stuff, and in CosmicSlot the focus is obviously on slots. But I'll point out that the section with classic games is good too, and besides the pure classics there are a lot of variations on the theme. Basically, the game selection made me happy. And everything else seems fine too.

The lobby at cosmicslot has lots of high volatility slots. And for slots it's definitely worh going there, especially if you already know your providers and know what's actually worth playing. The loyalty program is dasigned really cool. It doesn't look like the usual VIP levels, either in design or in the offers for regulars, so big plus for that.

AVOID

Ive used dozens of online casinos over the years and this has been the most frustrating of them all. Their online chat dont answer anything, just pass you off to other departments to deal with over email. It takes 3 days then to receive generic email responses which dont address the actual issue. They keep moving the goalposts on whats acceptable for KYC verification. They reject acceptable documents as per their request and then say oh it has to be this way or that way. Do anything they can to reject, delay and stop you cashing out. Its been the worst customer experience Ive ever had at any casino in 15 years. AVOID AVOID AVOID.

Update: I won 7k. Withdrawls limited to 500 a day but they take days to even process one cash out. They constantly delay and then say the finance department is "under pressure, please wait a little longer". They do this in the hope you lose the funds before you get them out of the casino.

Without doubt the WORST casino I have ever played at. Just a horrible experience from start to finish.

Did not receive my withdrawal.

I have been completely verified, but still have not received my withdrawal after a week and a half. They say that the withdrawal has been reviewed and funds have been payed out, but they are waiting for the payment team to process it? This does not make sense to me. Sure seems like a huge scam and I will never get my money. Do not deposit with this casino if you ever want to make a withdrawal.

Overall, the casino is good, there are a lot of games, and the most interesting thing is the fast withdrawal of funds. According to their terms, within three business days, as it is written, so it is done. Thank you.

Slow and poorly designed

This is one of the slowest and poorly optimised websites I have ever had the misfortune of using. Games appear weirdly aligned meaning you sometimes can't see the balance and wins at the bottom. The search is also incredibly slow to load and finding the game you want is a nightmare.

I can't comment on withdrawals as I haven't tried that yet but avoid this casino.

I like the variety of games on CosmicSlot. There are seriously so many. And not just slots, but a bunch of other games too, including live casino. Honestly, I'm impressed. And overall, CosmicSlot has a nice interface, everything is easy to find, sections are convenient. So far, I have no complaints about the casino.

If you wanna play all kinds of slots

If you wanna play all kinds of slots, I can definitely recommend CosmicSlot. Of course, there are tons of games here, not just slots, but I mostly pick a casino for slots and I was happy with this one. I've read in other reviews about live casino, fast support, the license and basically solid basic security, and yeach, that's all true. Playing, I felt safe.

Scam! Steer away from this casino.

Scam!! They process their deposits under different MCCs to bypass any laws or gambling blocks a country may have. They do not process withdrawals and their support team is basically useless because they don’t answer for over a week. Do not use this casino!!
