Cosmic Slot is an online casino that is owned and operated by Altacore N.V Casinos. Altacore has previous experience in the crypto-casino sphere, operating several sites including All Reels Casino, which we reviewed here. We’ve generally found its casinos to be of a good caliber so we’re hoping for more of the same here.

CosmicSlots is quite the feast for the eyes. The site has a space theme and it’s fair to say that the homepage is busy. There is a lot going on here – a banner displays the bonuses, while you can scroll down to see the selection of games and an activity screen. This is similar to a newsfeed, with your latest messages, as well as big wins being scored elsewhere displayed here. This becomes more personalized the more you use the site as well- displaying information from games you’ve enjoyed playing yourself. While this isn’t anything spectacular, personalization is always a nice touch and adds to the experience.

Cosmic Slot is quite the feast for the eyes.

While there is quite a bit of visual clutter, I still found Cosmic Slot to be a very responsive website that is well-designed. Everything is easy enough to locate and the menus are all in logical places. The sign-up process is kept nice and simple, and depositing funds is also a very speedy procedure.

If you want to spin the reels on your mobile device then you shouldn’t run into any problems either. I tested the casino on both and Android and iOS device and found that it runs very smoothly on both of them. There is no mobile application available for the casino but given the quality and speed of the mobile site, there really is very little need for one anyway.

Slots & Games

Cosmic Spins Casino gamepage

One area I really enjoyed at Cosmic Slot was the game selection. The operator is home to over 3,000 games and you can find some real quality on offer here. Big names like Yggdrasil and NetEnt operate alongside smaller companies like Triple Cherry and Edict to make sure that players will never be bored while playing here.

Navigating your way around the game section and finding what you are looking for is a very straightforward process. There is a filter that allows you to search via the developer, which I always find to be a useful touch, as well as useful categories at the top including jackpot, Megaways, live casino, hot, and table games. Of course, there’s also a search bar, which is perhaps the most useful feature for a games page to have.

Tucking into the slot sections itself, you’ll find classics like Gonzo’s Quest and Starburst sharing a home with more modern hits like San Quentin XWays, Jammin Jars 2, Reactoonz 2, and more. There’s a little bit of something for everybody here.

That includes those who want to get their hands on big wins will find a reasonable array on offer. Microgaming is a notable absence from the game collection, which means titles like Mega Moolah can’t be found here. There are still some good jackpots to be won though and some enjoyable titles including the likes of Chilli Heat, Wolf Gold, and Divine Fortune. There is also an entire section dedicated to Megaways where you can try your luck on games like Fishin’ Frenzy Megaways, Buffalo Rising Megaways, and a good range of other titles.

Of course, all of the casino’s products are easy enough to access on mobile devices. We’ve already discussed the ease of use on mobiles, and you’ll be glad to know that the game collection all runs smoothly on smaller screens as well.


Cosmic Spins Casino Promotions Page

Cosmic Slot is not messing around when it comes to its welcome bonus – offering customers a deposit bonus and free spins for their first three deposits on the site. This is how they break down:

  • First deposit: 100% up to €400+100 free spins
  • Second deposit: 75% up to €300 + 50 free spins
  • Third deposit: 50% up to €300 + 50 free spins

In order to get your hands on free spins, then you will need to deposit a certain amount. For each of the three deposits, you will need to deposit €20 if you want to be able to claim just the deposit bonus, whereas if you want the free spins, you will need to wager €50 or more. On the whole, a potential €1,000 deposit bonus and 200 free spins is certainly not a bad welcome bonus.

What about the terms & conditions I hear you ask? Well, they’re a bit of a mixed-bag. The free spins come with a wagering requirement of 40x, while the deposit bonus is 35x both the bonus amount and the deposit, which is a little steep in my opinion. The maximum amount that a player can wager using their bonus funds is €5, and all bonus funds must have been wagered within ten days of depositing, which can be a little demanding.

The rest of the bonus selection on the site is quite good. There are three weekly bonuses that you can claim which could keep you coming back. There is a weekly free spins bonus which is handed out every Wednesday providing that players have deposited at least €25 in the previous seven days. Like the welcome bonus, these come with a 40x wagering requirement. There is also a 10% cashback for those who have deposited €50 or more in the last week – the max that can be claimed with this is €300, which is fairly generous. It’s also a good way to keep customers coming back every week as well.

Finally, there is a weekend bonus where players can claim a 50% bonus up to €100, as well as 50 free spins. Like the welcome bonus, this will depend on the amount you deposit, with players needing to deposit at least €50 in order to get the 100 free spins. The slots you can use on the free spins will vary on the promotion and they are updated regularly.

One thing that I felt was missing from the bonus section was any crypto-focused bonuses. The casino doesn’t really seem to want to promote crypto-gambling all that much, as is evident through the lack of these kinds of promotions. This is unfortunate and is definitely something that works against the site.

Users Reviews & Customer Support

As with most casinos, you can find a mixed bag of user reviews for Cosmic Slot online. The majority of the ones were fairly positive though, with the site’s easy sign-up process and gaming options being praised.

Like I did, several customers took issue with the depositing options, pointing out that the casino really doesn’t support players on a lower budget who want to use cryptos. The processing time of payments has been met with a lot of praise though. The live-chat team was also praised, with many saying that they were able to get hold of the information that they needed with little to no fuss.

That said, the casino doesn’t take the time to respond to criticism online. I always feel as though operators are missing a trick when they fail to do this and it can also make them look incompetent, especially if their competitors are making the effort to do so. While some of the negativity is no doubt from people who have lost money and feel as though they have been mistreating, there are still plenty of genuine complaints which the casino would be wise to respond to.

As far as customer support goes – there is a live-chat option available in the bottom corner of the site. The responses from this are quick, though, and are very useful. The casino does list a phone number and some e-mail addresses. On further inquiry though, it turns out that the number listed on the site is not there for customer support, which is a little bit misleading.


There were many things I liked about Cosmic Slot but the depositing options were not one of them. The selection available is not too bad – the casino has embraced cryptos and allows players to use Bitcoin, Ethereum, Tether, Litecoin, Dogecoin, and a few others. While it’s not quite the same amount that you would find at somewhere like FairSpin Casino, but it is still respectable. Given that it does seem to feature smaller tokens, it is safe to assume that the operator is regularly updating the number of options that are available for players.

The problem, however, is the high minimum deposit that is required to play. While the minimum for other methods is set as low as €20, for cryptos, players must deposit the equivalent of €50. Given the fact that cryptos tend to be a more economically viable option for casinos, this is definitely a little bit of an odd choice. What makes this even more frustrating is the fact that the casino will also only allow you to withdraw with crypto. This also comes with a €50 minimum and you can only take out a max of €400 per day, which is quite limiting if you are a bigger spender.

For me, crypto gambling is supposed to make casinos easier to use and more accessible, and having a higher deposit amount to play with crypto just seems like a bit of a backward step. If the casino wants to encourage players to use the service, then it should really drop the price of this one.

Is Cosmic Slot available in the UK?

No, sadly not. Cosmic Slot does have quite a few geographical restrictions in key markets, including the UK, US, Netherlands, France, and Germany.

Does Cosmic Slot have a mobile application?

No. There is currently not a mobile application available at Cosmic Slot.

What are the withdrawal limits?

Players are able to withdraw up to €400 a day from the site, or the equivalent in other currencies.

Is Cosmic Slot Casino safe?

Yes! Cosmic Slot is licensed and regulated by the government and laws of Curacao and proudly displays its licensing information at the bottom of its webpage.


Cosmic Slot Casino is not without its flaws but there is still plenty of good stuff to enjoy here. The bonus and promotions section feels like a particular highlight. While there is not a huge focus on cryptocurrencies, the bonus selection is still fairly strong and it offers players a warm welcome and a chance to win some decent cash. Being able to claim bonuses for your first three deposits is never a bad thing. That being said, the wagering requirements could be lower.

The lack of focus on cryptos is definitely something that does work against the site though. There are no crypto-bonuses, and the site has a higher deposit limit for cryptos than it does for fiat-based deposit methods. This does leave a bit of a sour taste if you are the kind of player looking to use crypto methods. That said, it does have a good selection of crypto-deposit options available which does help redeem it in this area.

The game selection is also a big selling point. While Microgaming is a notable absence and is always something I’m dissappointed not to see, there is still plenty of depth available. The casino has plenty of range with its gaming options and it is very easy to use. On the whole, Cosmic Slot is still a casino that is worth visiting, but it is not necessarily a site that is going to be great if you want to play with cryptocurrencies.

Definitely needs more of a crypto focus. Still a good site though.

Good review, good site. I joined after finding it on here. Didn’t win, but didn’t have any issues and got a good bonus and a couple of hours of gameplay out of it.
