I took the time to play through several games available at Kosmonaut Casino to give you a better idea of all the great games they offer.
- Elvis Frog Kosmonaut by BGaming
I love seeing online casinos having exclusive and original games that you can’t find elsewhere, and that’s exactly what Elvis Frog Kosmonaut is. The casino and BGaming teamed up to bring one of the provider’s most beloved characters to an exclusive online slot that features blazing wheels, free spins, a hold and win bonus game, and jackpot prizes. Elvis Frog, himself, serves as the game’s wild symbol, and he’s still here to serenade you win you get a big win.
While this game doesn’t really offer anything different from the original Elvis Frog in Vegas online slot, it’s still refreshing to see the character in a new environment. If you like the original, you’ll love this game. Hold and win slots are still trending with many casino players, and this one offers plenty of good-sized wins.
- Immersive Roulette by Evolution
You’ll find plenty of live dealer games and game shows to play at Kosmonaut’s live casino, including live blackjack, live poker, and multiple roulette variations. Immersive Roulette is really a live dealer game created to show off Evolution’s impressive video technology. The game is played like any other live roulette game where you can place your wager on red/black, odd/even, numbers, or whole sections of the board. The live dealer will spin the wheel, and if you wagered wear the ball lands, you’ll receive a payout.
But as I said, this variation heavily focuses on immersing players into the game via the videography. So you’ll notice lots of camera angles that range from on top of the wheel to beside the live dealer and others. This is especially true when the ball stops on the wheel as the camera action suddenly moves into slow motion as you wait to watch the ball fall. Me, I find it distracting from the gameplay, but I can see where some players might enjoy it.
- The Myth by Mascot Gaming
Fans of Norse/Viking-themed games will enjoy The Myth online slot game. The game features a 5×3 grid and has an RPT of about 95%. This online slot also features a bonus game where players can win up to 25 free spins. But the big thing here is what the game has dubbed a “Risk’n’Buy” feature. This feature is available after every spin, even if there is no win. Should you accept, you’ll instantly be taken to one of the four free spins games for a chance at some of the game’s biggest wins.
There are four different bonus games in The Myth. The first is the Dragon Free Spins, where you get 10 spins one random reel will become a full reel wild on each spin, as well as any other reels where a wild lands. The second is the Vikings Free Spins, where you get only 5 free spins with wild symbols that convert any adjacent symbols to wilds. The third bonus game is the Skadi Free Spins, which kind of plays out like a hold and win game. And the last bonus game in The Myth is the Wolf Free Spins which comes with random wilds. Additional free spins can be won in all bonus games.
- Aviator by Spribe
While you won’t find many crash games at Kosmonaut, you will find one of the most popular. Spribe’s Aviator is one of the top crash games you’ll find at crypto casinos. Gameplay is simple. Just place your wager and hit cash out before the plane flies away. You’ll receive your wager plus multiplier upon completion. Crash games such as aviator are quite popular among crypto players as they are seen as one of the fastest ways to multiply your crypto.
- Absolootely Mad: Mega Moolah by Microgaming
If you’re looking for huge progressive jackpots, you can never go wrong with a Mega Moolah Slot, and Absolootely Mad has a reputation for having one of the largest payouts in online slot history at $23.6 million back in 2021. In addition to a great theme centered around the infamous works of Lewis Caroll, the game also features cascading wins, a free spins bonus game, and a multiplier trail to increase your winnings up to 15x. While many enjoy playing Mega Moolah slots, it is important to note that they are notorious for their very low RTP at 92%.
Despite its low RTP, Absolutely Mad is a very fun online slot to play. The Mad Hatter character chuckles and makes comments throughout the game. So while this slot game doesn’t really offer anything new, it is still captivating players into its Wonderland world. To trigger the game’s progressive bonus wheel, you’ll need to collect a lot of gold coin wild symbols into your teapot. Once you have enough, the bonus wheel game will be triggered, where you will spin to win one guaranteed jackpot prize.
- Astro Legends: Lyra and Erion by Foxium
I’m not sure why Astro Legends is under Casual Games at Kosmonaut, but that’s where you’ll find it. This is a very unique online slot that is like nothing else I’ve ever seen. The game’s board almost forms a diamond, and all matches payout via cluster wins. This retro-themed slot also features multiplier wilds, respins, and a Lyra Spirit Bonus game that has to be seen to be believed. In it, you have a wolf that has three lives. You’ll try to get through all seven levels of the bonus game while collecting as many gems as possible without being hit by Erion. You’ll win a 20x multiplier if you get through every level.
I love everything about this game! The two characters battle each other through the game and interact with one another. The soundtrack is great, and I love the 80s retro style of the digital artwork here. There are no scatter symbols. Instead, you’ll need to collect 100 Stardust Bubbles to trigger the bonus game. It takes a while, as they appear at random, but once you do, it’s well worth it. Everything about this slot game made felt completely innovative and fresh. If you’re an online slot player looking for something new and/or totally different, I highly recommend checking this one out.
Design, Experience, and Mobile Compatibility
Overall, I’m left with a positive impression of Kosmonaut’s platform. In the top menu, you’ll find all the information you need on payment methods, casino bonuses, the VIP program, and slot tournaments. Games can be easily sorted by categories, providers, or you can use the search feature to find a game by name. And at the bottom of the site, you’ll find pages for Responsible Gaming, Bonus Terms and Conditions, and the FAQ.
I also tested the casino site on my mobile device and found that all features are fully optimized for both iOS and Android devices.
Customer Service and Support
Should you have any issues or questions while playing at Kosmonaut, you can contact customer support via the following methods.
• Contact form
• Live chat
My biggest complaint about Kosmonaut actually involves their live chat feature. Every time you change a page you are on, the chat pops up and makes a “bubble sound,” asking, “Welcome back, let us know if you have any questions.” It was actually rather annoying. I understand that they are letting me know that live chat is available, but let me walk through your site in peace, please.
However, I did test out the live chat support and found them very helpful and knowledgeable. The FAQ does not have much information on it, so most users will probably not find it very helpful and will need to resort to the chat support.
Deposits, Withdrawals, and Security
All deposits and withdrawals at Kosmonaut are instant for crypto players, and there are no withdrawal fees. You can use any of the following cryptocurrencies at this online casino.
|Crypto||Min Deposit||Min Withdrawal|
|Bitcoin||0.00006 BTC||0.0002 BTC|
|Ethereum||0.01 ETH||0.01 ETH|
|Litecoin||0.01 LTC||0.01 LTC|
|Bitcoin Cash||0.00006 BCH||0.0002 BCH|
|Tether||0.0001 USDT||0.0001 USDT|
|Dogecoin||0.01 DOG||0.01 DOG|
|Binance||0.01 BNB||0.01 BNB|
|Tron||10 TRX||10 TRX|
NOTE: When it comes to withdrawal limits, the site is rather vague. I found the following in the casino’s terms and conditions, “The maximum amount for withdrawal depends on the payment method you use. If the requested amount exceeds the limit of a particular payment system, the amount will be withdrawn in installments.”
Kosmonaut Casino’s site states that they use the best and most innovative technologies protected by industry-standard encryption technology. This means that all your personal data and any activity you make on the site will be kept completely private.
Overall, I had a very enjoyable experience at Kosmonaut. In fact, this might go to the top of my list of one of my preferred crypto casinos. Let me count the ways. First, they have a great game collection that they are working ever to expand and broaden. Second, it’s one of the only crypto casinos where you can find a no wager free spins bonus; and it’s not just a one-time event. You get them every week! And finally, I love the low deposit and withdrawal limits, as that makes it much easier for me to collect my winnings.
What would I change? I do wish the casino site would not be vague about maximum withdrawal limits. While such things usually only affect high rollers, it’s still good information to know. Also, in my opinion, the terms and conditions of the welcome bonus are not the best for most players. The wagering requirements are far too high (50x) to realistically meet them in the time frame given (3 days). And my other complaint would be that their team needs to put some love into their FAQ page. Just add more information. But these are all relatively minor things in the grander scheme of things.
In the end, I highly recommend checking out Kosmonaut Casino. It’s one of the best casino sites crypto players will find. Thanks for the experience Kosmonaut, you’ve certainly made a casino cosmonaut out of me!
