Cosmobet Arvostelua 

Can't get the verification through.
They don't respond to emails. Chat takes forever to get through. Really bad customer service

I just deposited £50 ! I verified everything! And I can’t play ? Cause it says NO FUNDS!? Wtf is that ?
Scammer’s.
Absolutely lack of communication! The life chat ? Waiting there till now ! Email ? Maybe I’m gonna wait for months . I just waste £50 !

Saying my Account cannot be verified, emailed to no avail. Don't have any issues with deposit but as soon as you try to withdraw encounter issues.

They cash out on small wins but do no if you win big.

Verified customer under Santeda International B.V. (MyStake, Velobet, Cosmobet, Donbet, Rolletto).
Self-exclusion ignored, withdrawals withheld (£2,800), SAR refused.
Complaint escalated to Curaçao GCB, ICO and Monzo. Evidence available

I used Cosmobet as they are non Gamstop whilst I was (unsuccessfully!)taking a break.
I have been pleasantly surprised. Obviously the casino is always the winner overall but I’ve found that I have had some pretty decent wins with Cosmobet. It really does not feel ‘rigged’ at all, as it does with many on line casinos. The range of games is good (No Pragmatic Play though!) Sports betting is good too - fast settlement. In terms of withdrawal, it tends to be in my account within 24 hours on a weekday. If it’s on a Friday - nothing happens til Monday.
My Gamstop restriction is now expired but I’m sticking with Cosmo rather than UK based casinos as I’ve found them fairer and had a far more enjoyable experience with them. And more wins! Also free bets and spins. I don’t sign up to bonuses though. Just awaiting a £1650 withdrawal to hit my account. Don’t let me down Cosmobet 😊

great casino, good selection of games

SCAM! DO NOT DEPOSIT ANY FUNDS INTO THIS SITE. They apply bonus funds to you deposit which h means you forfeit the ability to make any withdrawals. I repeat. Do not use this site. You will not be able to withdraw it

Trying to verify my account and everything I’ve uploaded for proof of address is apparently invalid. I’m from UK so don’t get sent paper bank statements. I try to upload a screen shot but unacceptable. I’ve sent letters dated within the last few days with my name and address on it. Even though it states it on my UK driving license too but invalid. I sent an email but no response. I have no option to even do a live chat. User name chloe95x
Update. I have withdrawn £7500 all in all in a week and the winnings hit my account by the next working day. Legit site and they only deduct a few pounds.

I had deposited some funds, ended up getting some free spins. won a few quid on the spins. then played roulette with the money and got it to over a £1000. Tried to withdraw a they cancelled it and took over £800 from my account.
Disgusting from a casino. steer clear

I looked at the comments and someone who gave it 5 stars wrote that it took 2 hours to withdraw money. Site representatives said in the chat section that the process takes between 24 and 48 hours, and sometimes this process may take longer...The other is to confiscate the player's own money and block his account due to the so-called bonus violation. So why do you confiscate the player's own money? If there is a bonus violation, the bonus earnings will be deleted... Fortunately, I did not deposit money into this casino and I was blacklisted.

I had my account closed due to gambling addiction. I then proceeded to create a new account (all the same details just changed my email address)

I deposited small amounts over £600.

I managed to win £500 and proceeded to withdraw, at this point they closed my account and refused to give me back any money saying I had 2 accounts! The first one I had CLOSED MYSELF!!

Avoid at all costs absolute scammers and are not licensed by the UK Gambling Commission.

These prey on people on GamStop ect. They are illegally operating in the United Kingdom as far as my reasearch tells me. I will be reporting them to the UKGC.

All you have to do is read the countless reviews that show how much they are scamming vulnerable people!

Don’t make the same mistake as the ones who have pointed out this is a scam site! Just avoid and save your money! These reviews don’t lie!!

Edit to your reply..

First account was deleted. Made a full new account so they wasn’t multiple accounts!..

The second account didn’t even use bonus as I don’t due to unfair wagering!

Deposited over £600 went to withdraw £500 and you closed my account. Your a scam website operating illegally in the UK

I placed a 170 EUR bet (ID 257628324) on George Russell to win the Formula 1 Singapore Grand Prix 2025 at boosted odds of 30.00. The market was openly available for 3 days, and my bet was active for 13 hours. Just 2 hours before the race on October 5, 2025, Cosmobet voided my bet, claiming a "technical error" in the odds, and only refunded my 170 EUR stake. George Russell won the race, making my bet a clear winner (4,930 EUR winnings at odds 30.00).
Their support (Henry/Support Agent, email and chat transcript submitted elsewhere) admitted the error was theirs but refused to pay my winnings or even compensate at the "correct" odds of 10.00 (1,530 EUR winnings), which I offered as a fair compromise. Voiding a bet so late, after 13 hours of acceptance and no prior warning, is unfair and feels like a deliberate attempt to avoid payout. This is unacceptable and unprofessional.
I’ve filed complaints with the Curaçao Gaming Control Board, AskGamblers, and Casino Guru, providing all evidence (chat transcript, email). I urge others to avoid Cosmobet – they don’t honor legitimate winning bets and hide behind "technical errors." I’m pursuing this until I get my rightful winnings!

excellent site staff very helpful would highly recommend

Parfait et meilleur que les autres sites web

Cosmo bet have gone to the length of trying to get me removed from this site for just wanting my money returned. They are a joke and should be shut down, not me silenced for calling them out.

If the wery nive gambling site and still gives nice win

Absolutely love this site. I have a favourite game on there and always enjoy playing it

Deposited £100, won £700. Requested withdrawal via SEPA at 6am yesterday. 11 hours later after withdrawals kept getting rejected I received an email asking me to send documents in. I sent documents in and now their KYC email stopped working and due to a technical issue they can't verify me nor accept the documents via an alternate way. Absolute joke of a site. Stay away at all costs.
