Design and functions

Cosmic Slot backs up its name with a space-themed website full of purples and blues. It looks decent enough – nothing special, but we’ve seen worse!

Everything is functional on both mobile and desktop. Simply log in through your device’s mobile browser and start playing. Cosmic Slot has made sure you can find all of its 3,000+ games directly on the homepage. Easy!

Also on the main page are various game categories, bonus information, and your account menus. It’s all put together in an efficient and modern way, as you’d expect from a crypto casino that opened in 2020.

Cosmic Slot game selection

There aren’t many online casinos out there that have more games in their locker than Cosmic Slot. There were over 3,000 games from 60+ providers at the time of this review. That’s truly an all-out collection, and you won’t find many crypto casinos with more variety and quality.

This is a good thing because you won’t find bingo or scratch cards here – it’s casino games only all the way!

With that many games, it’s important that you can filter and sort them easily. And Cosmic Slot delivers on this front, too. There’s a search bar for looking up titles and categories, as well as the option to sort by popularity, developer, date of release, and various different features like MegaWays or bonus rounds.

Just a few of the top casino game developers you’ll find on offer at Cosmic Slot include:

  • Amatic
  • Booming Games
  • ELK Studios
  • Microgaming
  • NetEnt
  • Play’n GO
  • Playson
  • Pragmatic Play
  • Push Gaming
  • Quickspin
  • RedTiger
  • Relax Gaming
  • Thunderkick
  • Yggdrasil

At Cosmic Slot, you’ll find some of the most popular slot titles of the modern era, as well as brand new games, including Book of Dead, Reactoonz 2, Fire Joker, Frozen Gems, Starburst, Twin Spin Megaways, Sakura Fortune, and Midas Golden Touch.

The live casino selection, often forgotten by casinos, is also stacked with loads of games from top developers like Evolution, Ezugi, SA Gaming, and Lucky Streak. That’s a massive game collection, all in all, so you’ll be spoilt for choice at Cosmic Slot. 

Cosmic Slot’s bonuses and promotions

Cosmic Slot’s welcome bonuses stand out almost as much as its huge game collection. You can bag yourself up to €700 with the welcome bonus alone. Then, there are reload bonuses and a loyalty program.

The welcome bonus is structured as follows:

  • 1st deposit – 100% in bonus up to € 200 + 100 free spins
  • 2nd deposit – 75% in bonus up to € 200 + 50 free spins
  • 3rd deposit – 50% in bonus up to € 300 + 50 free spins

You need to deposit at least €20 or crypto equivalent to get the bonus cash in each part. A €50 deposit is needed to claim the free spins. If you choose to give the casino your phone number and then verify it, you’ll also get ten free spins. This might be worth it for the two-factor authentication, let alone the free spins, as long as you aren’t fully committed to the crypto anonymity.

Bonus cash comes with a 35x wagering requirement at Cosmic Slot, which is about average for online casinos.

But what other bonuses can you get here?

Recurring weekly bonuses

You get a weekly reload bonus to start with. Simply deposit €25 to claim 50 free spins. There is a 40x wagering attached, and you can only claim the offer once a week.

Then there’s the weekend bonus, which drops every Friday. This one gives out 50% up to €100 and 50 free spins and is open to everyone but first-time depositors. The same wagering rules apply as the ones attached to the welcome bonus.

Lastly, we have our personal favorite bonus at Cosmic Slot – 10% cashback up to €300 every single week. If you deposit €50 or more (or crypto equivalent) between any given Monday and Sunday, the following Monday, you’ll be credited with 10% of your losses as cashback with a low wagering requirement.

Apparently, there are even more offers available for regular players on Cosmic Slot’s Telegram channel. If you don’t know Telegram, it’s a less restricted social media slash messaging app, which many crypto enthusiasts love. Check out Cosmic Slot on Telegram for some exclusive offers!

Loyalty program

On top of all those bonuses, Cosmic Slot also runs a loyalty program. Information is a bit thin on the ground via the website, however. Despite our decades of experience with online casinos, we left not exactly sure how it works – and this doesn’t happen too often.

What we are sure of is that you collect points by playing games and that you can see those points on the site’s side menu. You then use your points to buy prizes in the Cosmic Slot “Store.” Prizes include free spins and bonus cash offers. The details of how many points you earn for what bet types remain a mystery. Intriguing or negligent? You decide!

Cosmic Slot payment methods

Cosmic Slot isn’t a primarily crypto casino, but it does offer a decent range of crypto options. In addition to VISA, MasterCard, bank transfer, and Neosurf for fiat currencies, the casino also accepts the following cryptos:

  • Bitcoin
  • Dogecoin
  • Ethereum
  • Litecoin
  • Tether
  • Tron

The minimum deposit at Cosmic Slot casino is €20 in fiat currency or €50 equivalent when using cryptocurrencies. The same goes for withdrawals.

Customer service

So far, Cosmic Slot has impressed us with its range of bonuses and huge game collection but let us down with a few things in other areas.

How does the site fare in customer service? Well, it did quite well. It features a 24/7 live chat, which is impressive. But, again, the official information was a bit lacking – to the point where we had to ask the live chat agent about their opening hours.

International players want to know they can always get support at a casino, and Cosmic Slot offers exactly that – so why not tell players straight away?

In addition to the 24/7 live chat, this casino also offers an email address, a phone number, and a Telegram channel. The email address isn’t in a contact form, so you need to manually copy and paste it into your email client. We did get a quick and helpful response to our email query, though.

The telephone line isn’t free and is based in Cyprus, so we’d avoid that if you don’t have a European phone number yourself.

Having a Telegram channel is kind of cool if you have the app. Customer service agents are apparently very active there, so it could make a change from the standard live chat.

Summary

  • Massive library of games – over 3,000
  • Big range of generous bonuses
  • Nice filter and sort functions for games
  • Some information missing from website
  • No FAQs or guides

Cosmic Slot is an excellent crypto casino in so many ways, but a few details keep it from being among the very best on our list. If you want games and bonuses but don’t sweat too much about the smaller stuff, this could be your casino!

With over 3,000 games from 60+ developers, including a few of the very best in the world, you’ll find many of the most popular and legendary slot titles ever at Cosmic Slot. It’s also super easy to sort and filter games, with everything presented nicely.

Then, there are loads of bonuses too – with up to seven or eight potentially available to you in your first week. This includes free spins, cashback, and bonus cash offers. Plus, there are regular bonuses and a loyalty program.

However, this is where we get into a recurring problem at Cosmic Slot – a lack of information!

All we wanted to know was exactly what games grant points for the loyalty program, and we couldn’t find this information anywhere. It’s great that there’s a loyalty program at all, so the casino should make it clear how to use it!

When it comes to customer service, it’s a similar story. The site features a 24/7 live chat, which is perfect and exactly what you want to see. However, this is not made clear anywhere on the site, and we had to ask the team itself for the opening hours. A bit silly!

There’s also no FAQ section at all. Admittedly, this isn’t the worst thing ever, but considering the effort Cosmic Slot clearly put into its games, we feel like a little more information for new players wouldn’t have gone amiss.

Still, these are all relatively minor negatives. If you like top-tier games and loads of bonus variety, which is a lot of what counts at an online casino after all, then Cosmic Slot has you covered!
