2024 Calvin Casino review: Pros & cons explained

Technical difficulties in the game library

This gambling site offers just over 1,000 titles. This is far from being a large amount, with the most reputable casinos now setting the industry average at between 3,000 and 5,000. For perspective, sites like Flush casino actually exceed these amounts and reach almost 6,000.

Still, on the face of it this wasn’t going to alienate me. After all, there are some excellent software providers available, so I wasn’t expecting a dismal performance. Unfortunately, while testing for this Calvin Casino review I uncovered several serious technical shortcomings.

Not to put too fine a point on it, the game menus just don’t work. Click on ‘Arcade’ and you stay on the same page. Click on ‘Jackpots’ - ditto. Can happen to the best of us, I suppose, so I decided to go back to the site later to see if these were resolved.

Two days on, it was still facing similar issues. I clicked on ‘Arcade’ and stayed on slots. I clicked it again, and this time it worked. Tried the same move with ‘Jackpots’ and it stayed on ‘Arcade’. I reached out to customer support for the second time, and received the same answer: we are working on it. I also asked for a specific link to live games but was told there wasn’t one and that I just had to ‘find them’.

Friends, it doesn’t take a genius to figure out something’s rotten in the state of Calvin - to cheekily paraphrase the Bard. Even if the technical issues are legit, any online gambling site facing such serious problems for longer than a couple of days doesn’t exactly scream ‘trust’.

My other big beef is that RTP values are not provided. Instead, I found a visual meter illustration with an arrow vaguely landing close to 100% for all games. Very disingenuous. Am I meant to guess exactly with decimal point closest to 100% the game falls under?

Like a total lemon, I had to actually look up the RTP for each game. This is also true of the section for Enchanced RTP slots, which is really rich. You’d think the whole idea of that section would be to tempt me with super high RTPs, but it’s not very tempting if I don’t actually know what these are. For all I know, they might not be enhanced at all. Bitcasino, for comparison, clearly indicates the RTP for every single name in the thumbnail itself - you don’t even have to click on it.

The section titled ‘Top Wins’ is sneaky. This category is usually used by other casinos like BitStarz to foster trust by showing me who won how much on which games. At Calvin Casino, you don’t get this information. Instead, there’s a list of games that are supposed to have delivered top wins, but I have no idea why or how. If you want to see how this is done properly, check out. There’s also a Feel Luck (and that’s not a typo, I swear!) menu that I’ve no clue what is meant to do.

On the plus side, I liked the ‘play random game’ option. Sometimes it’s fun to be surprised. It’s not much, I know, but that’s all I can give you.

The platform should introduce some crypto payment options

Naturally, my biggest beef is that you can’t use cryptos at this casino. If you’re looking for the best crypto gambling sites, this is not it. If you’d like to check out a casino that accepts a grand total of 19 cryptocurrencies, allow me to direct you to Stake.com. You’ll find all the popular choices like Ethereum, Bitcoin, Litecoin, USDT, and more here.

Confusing withdrawal speed

Cashout options are too few, as you can only use eWallets, card accounts, and bank transfers. Moreover, the minimum cashout amount of €25 is quite high when compared to the industry gold standard of €10. If you decide you don’t like the site and you want to cash out your account, you’re pretty much stuck there until you gather €25 in wagering.

I also wasn’t happy to find very vague terms regarding withdrawal speed. Instead of telling me how long the cashout takes to be finalized, Calvin Casino only specifies the ‘pending period’, which is the time it takes to finish Know Your Customer (KYC) checks. Following that, the transaction still needs to be processed by the casino, but I couldn’t find any information about how long that usually takes.

Limited bonus offer

The welcome bonus of up to €300 plus 100 free spins is not huge when you consider sites like FortuneJack offer crypto bonuses up to 6 BTC (approximately €50,000+) or a 20% cashback. However, the 40x wagering requirements and 30 day expiry term are very reasonable.

I wasn’t fond of the way the spins are apportioned, though. You receive them in batches of 20, but only after you’ve used up your bonus cash. Typically, these are given out concurrently.

There are more match deposits for the second and third one, up to €300 and €700 respectively, as well as a Refer A Friend offer of 1% on every bet, with no limits. As tempting as this sounds, I won’t be referring any friends.

The mobile version could use an improvement

I have to say that I’m not fond of the idea of downloading an APK to my devices, especially if they contain the same faulty coding as the desktop site. I’ve no idea what the files contain and I won’t be installing them. That said, I did access Calvin Casino using the regular mobile browser and, surprisingly, I encountered no actual UX issues. The menus adapt very well to the interface of my mobile - they still don’t work, though.

Solid safety measures

The site is licensed by the Malta Gaming Authority, which typically keeps a tight leash on its licensees and it should be an indication of a basic level of safety. I was also somewhat mollified to see that KYC processes are taken seriously, as are responsible gambling tools.

The latter are so honed that I kept being forced to take one minute breaks after every hour I spent on the site. These breaks are mandatory. It may not sound like much, but it may be exactly what someone needs.

Underwhelming customer support

I can’t fault the speed of the reply that greeted me on live chat. And it was clear that I was actually talking to a human, rather than being fobbed off onto a chat bot. The support agent did her very best, but the reply just was not satisfactory. She had no idea how to direct me to this mythical live dealer section, and I left none the wiser as to why the game menus keep glitching.
