Ever seen a cat in a spacesuit? I know, it’s a strange question. But it seems that anything is possible at Kosmonaut Casino, even this peculiar sighting. Kosmonaut was established in 2020 and has since become a gambling destination that offers more than just a betting platform by providing a unique gaming experience with an exciting space-age theme.

This casino accepts 18 currencies which include 6 cryptos with simple deposit and withdrawal methods. The casino even has its own currency, called the Kosmocoin, but we’ll get there soon. Account registration is complete in the blink of an eye, or should I say, at the speed of light to fit the theme?

Welcome to the fabulous Kosmonaut Casino

An extensive collection of casino games provides Kosmonaut players with more than enough options to satisfy their gaming needs in all categories you could imagine. With over 2,400 stellar games to choose from in Slots, Table Games, and Live Casino categories, and a game section dedicated to Bitcoin and crypto games only, this menu might just be one of the best in the galaxy.

Kosmonaut offers 2 weekly reload bonuses and a welcome package that would put the stars in any player’s eyes. The space-themed VIP rewards program offers an opportunity to embark on a rewarding journey through our solar system, grabbing sensational prizes along the way with each level represented by one of the 9 planets. Now gear up for the adventure and let’s see what this rocket to riches has to offer.

Bonuses and Promotions

Not much can be said about the welcome package other than it being out of this world. And with 2 weekly reload bonuses one can certainly see that rewarding players is important to this casino. Kosmonaut also offers other promos in the form of tournaments, but let’s start off with the welcome package.

Welcome offer

Your deposit bonuses will automatically be issued after making your deposits, but make sure you meet the minimum deposit requirements to receive the bonus. All bonuses that form part of the welcome package are subject to a 45x wagering requirement, which is slightly higher than usual, but you do have 7 days to complete the playthrough before it expires so time is on your side.

The Kosmonaut Casino Welcome Bonus Pack

The welcome package consists of a bonus on your first 3 deposits and also includes free spins with each bonus. Let’s break it down:

  • 1st Deposit Bonus = 100% up to €100 or 0.25 BTC + 25 free spins
  • 2nd Deposit Bonus = 50% up to €200 or 0.5 BTC + 50 free spins
  • 3rd Deposit Bonus = 100% up to €200 or 0.25 BTC + 25 free spins

This comes to a total bonus amount of 250% up to €500 or 1 whole BTC which is an attractive offer indeed, not to mention the 100 free spins that come along with it.

Wednesday Reload Bonus

A little midweek mayhem never hurt anybody, right? I guess it depends on how you look at it. Kosmonaut Casino gives players the chance to up their game on Wednesdays with a free spins bonus on their first deposit of the day.

The Wednesday Reload Bonus at Kosmonaut Casino

By using the bonus code COSMOW when making the deposit, players can redeem 20, 50, or 100 free spins to use on a selected game. This bonus has a 45x wagering requirement and also lasts for 7 days, so I’d say go for the 100 free spins and finish off the rest of the week in style.

  • For 20 free spins – Deposit a minimum of €20 (or currency equivalent) or 0.00045 BTC
  • For 50 free spins – Deposit a minimum of €50 (or currency equivalent) or 0.0011 BTC
  • For 100 free spins – Deposit a minimum of €100 (or currency equivalent) or 0.0023 BTC

Friday Reload Bonus

There’s no better way to start the weekend than with some extra ching-ching to throw at the reels and tables. Claim a 50% bonus on your first deposit of the day, every Friday with this excellent offer. This one even includes 30 free spins to be used on a selected slot. Use the bonus code KOSMOFRIDAY when making the deposit and your weekend is off to a stellar start.

  • 50% Bonus up to €200 or 0.0046 BTC – Minimum deposit of €20 or 0.00045 BTC

Just like the Wednesday Reload Bonus, this offer comes with a 45x wagering requirement and is valid for 7 days from activation.

High Roller Bonus

To all the high rollers out there, this one’s for YOU! But don’t be fooled by the name, this offer is available to all players that meet the minimum deposit requirements to receive the bonus. The offer can be claimed only once every 2 weeks, but it is a very rewarding bonus, to say the least.

  • 50% Bonus up to €1,000 or 0.025 BTC – Minimum deposit of €350 or 0.0087 BTC

The High Roller Bonus at Kosmonaut Casino

Use the bonus code HIGH50 when depositing €350 or 0.0087 BTC or more and you could receive a 50% bonus on your deposit. As with all deposit bonuses, a 45x wagering requirement applies to the bonus amount only, and the bonus will be valid for 7 days from activation.

VIP Program

A big thumbs up for creativity, and also the rewarding benefits of this exceptional VIP program. There are 9 levels and rewards get bigger and better as you progress through each level. Oh yes, and get this, each level is named after one of the planets in our solar system – how cool is that? Very creative indeed and certainly suits the casino’s theme.

Each level offers a different cashback deal which unfortunately comes with a wagering requirement stipulated in the terms. But don’t worry, it’s a measly 10x so it won’t be too much of a hassle. All the cashback bonuses will only apply to slot games, so if you’re a table turner, you’re going to get some time on the reels whether you like it or not.

The Kosmonaut VIP rewards Program

To progress through each level, you’ll need to earn a certain amount of Kosmocoins. Never heard of these before? It’s Kosmonaut’s native currency, and it can be earned by playing your favorite slots at the casino. You’ll earn 1 Kosmocoin for every €20 wagered, which seems like a lot but remember, you don’t have to lose €20, it’s for all the bets totalling €20.

Let’s check out the VIP Program level for level:

  • Level 1: Neptune – 100+ Kosmocoins required to reach this level for 5% cashback weekly.
  • Level 2: Uranus – 500+ Kosmocoins required to reach this level for 6% cashback weekly.
  • Level 3: Saturn – 1,000+ Kosmocoins required to reach this level for 7% cashback weekly.
  • Level 4: Jupiter – 1,500+ Kosmocoins required to reach this level for 8% cashback weekly.
  • Level 5: Mars – 2,000+ Kosmocoins required to reach this level for 10% cashback weekly.
  • Level 6: Earth – 2,500+ Kosmocoins required to reach this level for 12% cashback weekly.
  • Level 7: Venus – 3,000+ Kosmocoins required to reach this level for 14% cashback weekly.
  • Level 8: Mercury – 4,000+ Kosmocoins required to reach this level for 16% cashback weekly.
  • Level 9: Sun – 5,000+ Kosmocoins required to reach this level for 20% cashback weekly.

Available Games

Kosmonaut offers over 2,400 games in total, with menus for Slots, Best Bitcoin Slots, Live Games, All Games, Jackpot Games, and Bonus Buy Slots (for those who don’t want to waste time triggering special features). Unfortunately, the non-live table games are not located in their own menu, so you’ll have to proceed to “All Games” and start searching if these are what you’re looking for, but the search function makes it simple.

Game Providers

Amatic, Baddingo, BbGames, BGaming, Boomerang Studios, Booming Games, Betsoft, EGT, Electric Elephant, ELK, Endorphina, Evolution, Ezugi, GamesInc, GamesLab, iSoftBet, Jade Rabbit, Mascot Gaming, Microgaming, NetEnt, NoLimit, Platipus, Pragmatic Play, Quickfire, Quickspin, Red Tiger Gaming, ReelPlay, Relax Gaming, and Silverback.

Slot Games

You’ll find over 2,200 slot games on the menu, which is a helluva lot of slots if you ask me. I’m surprised to see so many games yet so few providers, and it’s impressive. I’m happy to see some of my favorite games on the list with BGaming, Platipus, and iSoftBet games representing.

Slots can be played in demo mode too, which is always great if you want to test the waters before diving in. When hovering your mouse pointer over the game’s icon in the menu, you’ll be presented the option to “Play for fun” or enter the game to experience the thrill of playing for real.

You also have the option to search games from certain providers with a drop-down menu located on the right side of the screen. And if you know the title of the game, the search function will find it in a flash. 

Table games

Here’s where it gets a little tricky. Non-live table games are not categorized in their own menu, you’ll have to search through the “All Games” section to find these, and it’s a little frustrating, to be honest. If you know the title of the game then the search function will help you out, but otherwise, you’ll have to scroll through the vast selection of games to find them.

Playing non-live Blackjack at Kosmonaut Casino

Eventually, you’ll find a few great table games on the menu, with Blackjack, Poker, Baccarat, and Roulette from various game providers. There aren’t that many, but what is there is certainly worth playing. I would like to see these games in their own menu in the future, but perhaps Kosmonaut is waiting for a decent stockpile before this option is viable.

Live Casino games

If you’re a live game lover, then you’ll be happy to see that Evolution’s games are on the menu. But you’ll also find others from well-known live providers such as Ezugi and Quickfire sporting a few of their games on the list.

You’ll find everything from Baccarat to Blackjack, Poker, Roulette, Dragon Tiger, Punto Banco, and even a few dice games too. There are a few gameshow-style and unique games too, such as Mega Ball, Monopoly Live, Dream Catcher, and Deal or No Deal.

Kosmonaut Casino Live games

All these games are 100% mobile friendly and can be played anywhere at any time, provided you have a stable internet connection. Certain live games also have multiple lobbies so you won’t have to struggle to find an open table all that often.

Design, experience and mobile compatibility

I’m very impressed with the design of this platform. The layout is simple and easy to navigate, and created in a way to compliment the theme, helping to portray Kosmonaut’s original identity from the first glimpse. The site is also fully compatible with mobile devices and operates without any issues.

The overall experience was more than pleasant, and navigation through the website came with ease. I like the fact that the lobby page is designed without cluttered images and useless menus. It’s smooth, simple, and classy all at the same time.

The Kosmonaut Casino lobby

One thing I really do like, and I mean REALLY like, is the information bar right at the bottom of the screen. Here, you can find the Terms and Conditions, Affiliate Program information, Privacy Policy, and contact details for Support. But this menu bar also features something for the crypto players with separate game menus for all the other altcoins accepted by the casino, and I love this.

Customer service and support

To be honest, I have a few issues here. Yes, there is live support, but unfortunately, the response time is very slow. In most cases, you’ll probably need to wait a few minutes before engaging with a support representative, and when you finally do, the service isn’t all that great either.

The Live Chat function is situated on the bottom-left corner of the screen regardless of the page you’re on. When you click on it, it will prompt you to select the category under which your issue falls. This is somewhat frustrating, because as you follow the prompts it just takes you to information from the terms and conditions, and you’ll have to start the chat all over again to find a representative.

One thing I do like is the fact that you can add a screenshot to your message to help explain your issue. But my overall experience with the Live Chat has led me to believe that support staff are either understaffed or possibly very inexperienced. I would expect friendlier service as well so I hope Kosmonaut works on the support because the rest of the casino’s attributes are rather fantastic.

Alternatively, you can send the support staff a message via email using the “Support” tab right at the bottom of the lobby page, or mailto:contact@kosmonautcasino.com

Deposits, withdrawals and security

Ah, always very important! The deposit and withdrawal procedure here works pretty much the same as most online casinos, and you have over 20 payment methods to choose from too, depending on your region and currency, of course. Kosmonaut accepts 12 fiat currencies and 6 cryptocurrencies, and you can hold all these currencies in your player wallet at the same time, which is great.

  • Fiat currencies – Euro (EUR), Canadian Dollar (CAD), United States Dollar (USD), Australian Dollar (AUD), Polish Zloty (PLN), Russian Ruble (RUB), Norwegian Krone (NOK), South African Rand (ZAR), New Zealand Dollar (NZD), Japanese Yen (JPY), Indian Rupee (INR), Brazilian Lira (BRL)
  • Cryptocurrencies – Bitcoin (BTC), Bitcoin Cash (BCH), Ethereum (ETH), Litecoin (LTC), Dogecoin (DOGE), Tether (USDT)

Payment methods

Visa, Mastercard, Maestro, Skrill, NetTeller, ecoPayz, Neosurf, CardPay, Rapid, Siru Mobile, Bank Transfer, Sticpay, Venus Point, MuchBetter, MiFinity, Purple Pay, Interac, Bitcoin, Ethereum, Litecoin, Dogecoin, Bitcoin Cash, and Tether.


To make a deposit, simply click on the green “Deposit” tab located at the top right corner of the lobby page, or click on your profile menu right next to it, and click on “Wallet”. A window will open in which you can enter your deposit specifications. You can choose the currency in which you want to deposit, and the deposit methods for the chosen currency will appear on the left. 

Kosmonaut Casino deposit options

Fiat deposits at Kosmonaut Casino

Once you’ve chosen the deposit method, you can start entering the amounts and bonus code should you need one. One thing I like about this is that your available reload bonuses are displayed underneath so you’ll never miss out on an opportunity.

Depositing cryptocurrency is even easier. Follow the same procedure through the deposit tab, and choose your preferred cryptocurrency. You will then be provided with a deposit address and a QR code to make it even simpler. You can then proceed to your personal crypto wallet and perform the transaction by scanning the QR code or inserting the deposit address. Once again, don’t miss out on the reload bonuses if these are of interest.


To withdraw your winnings, enter your profile menu, proceed to the wallet, and click on the “Withdrawal” tab. Choose which currency you’d like to withdraw, and then your method of withdrawal. You can even withdraw your fiat balance into a crypto wallet.

With fiat currency withdrawals you’ll notice that there are fewer methods to perform the transaction than there are when depositing, but this is normal. After you’ve chosen the method, you can enter the amount that you’d like to withdraw and complete the necessary information required for the withdrawal method.

BTC Withdrawals at Kosmonaut Casino

With cryptos, simply enter the amount you’d like to withdraw, paste your wallet address in the space provided, and click “Withdraw”. Your valued cryptos will now be on their way to you and will arrive in your personal wallet in a flash. The minimum withdrawal amount will be shown when your payment method is selected, but it’s generally €20 or the currency equivalent.


Your player account can only be accessed by using your unique ID and password. You can take the security one step further by enabling two-factor authentication to fully secure your player account. Kosmonaut Casino also explains in their terms and conditions that they are bound by strict legal conditions to protect your personal data, and as a fully licensed casino owned and operated by Dama N.V., Kosmonaut is one you can trust.


I had a great experience playing with Kosmonaut Casino. I really enjoyed the creative platform and unique style. You can never go wrong with a space theme in my opinion, and I like the way they’ve done it. I had very few issues besides the support, and I would say the wagering requirement on bonuses is a little steep, but other than that, I would say this casino is on the road to greatness.

The game selection is more than enough to keep any player entertained, but I’m looking forward to seeing more providers on the list in the future. I would say that the non-live table games need their own menu, but as mentioned in the “Available Games” section of this Kosmonaut Casino review, this can easily be overcome. The website is easy to navigate, the menus are set up very well, and the terms and conditions are easy to understand. 

I’m a big fan of Kosmonaut’s VIP Rewards program. I think the way that the casino’s theme has been integrated with the program is rather clever and very unique. 2 Reload bonuses a week will certainly put a smile on MY face, not sure about you, but I’m all for it. And the welcome package is a great one, especially when you consider the 1 BTC maximum bonus.

Overall, Kosmonaut Casino is definitely a winner, and could certainly make a winner out of anyone. Thanks for the experience Kosmonaut, you’ve certainly made a casino cosmonaut out of me!
