Quick Facts

  • Daily crypto cashback of up to 21% through Bitcoin, Bitcoin Cash, Ethereum, Dogecoin, Tron, etc.

  • Thousands of slots are available, and new slots are added every day.

  • Some of the best software providers are available here, including Amatic, Evolution, NetEnt, Microgaming, and Play’n GO.

  • Great selection of bonuses for new and returning players, including a welcome bonus that includes the first three bonuses.

  • A VIP Club with 9 tiers is currently available for regular users.

Game Selection

This casino is mainly dedicated to slots, considering there are thousands of slots but not the same number of table or live dealer games. You can use the filter to single out games from only one provider, whereas there are 50+ software providers.

One of the features we love is that most games are available in demo mode for people who want to play just for fun. There is also the option to single out crypto games, which is perfect for players interested in depositing with cryptocurrencies. Crypto fans can even find a whole category dedicated to Bitcoin Slots, including:

  • Bastet and Cats

  • Fruits of Luxor

  • The Myth

  • The King

The only downside of Kosmonaut is that there are not enough table games. If you want to play roulette, poker, blackjack, or baccarat, you might have to resort to live dealer tables.

Bonus Offers

As for the bonuses, this platform has one of the best promo sections among crypto casinos. Most bonuses come with bonus codes, so you must be careful to use the code to receive the deal.

Welcome Bonus

The best bonus for new players is the welcome bonus for the first three deposits. Here is what you can get when making a qualifying deposit:

  • First deposit bonus – 100% deposit match up to $500 + 50 FS with bonus code KOSMO1

  • Second deposit bonus – 75% deposit match up to $200 + 75 FS with bonus code KOSMO2

  • Third deposit bonus – 100% deposit match up to $300 + 25 FS with bonus code KOSMO 3

Each bonus has 40x wagering requirements and is valid for only 3 days. So, you must use the free spins and fulfill the rollover requirements if you do not want to lose them.

Crypto Bonuses

Many cashback, reload, and other deposit bonuses are available at the casino. However, the best one for crypto players has to be the crypto cashback bonus which can give you a total cashback between 11% and 21%.

This bonus is available daily for a deposit made through any cryptocurrency available. The rollover requirement is 3x, whereas the cashback is given only to players who have lost less than BTC 0.0002, BCH 0.03, Doge 80, ETH 0.01, LTC 0.1, or USDT 20 when betting the previous day.

Banking Options

At CryptoCasinos, we love that this casino offers many options with instant processing times and no fees. You can make deposits and withdrawals using Bitcoin, Bitcoin Cash, Ethereum, Tron, and other cryptocurrencies. Here is an overview:

Customer Support

If there is a platform with pristine customer support, it has to be this one. Whether through the website or the app, you can easily contact customer support agents who are happy to help with anything. You will be connected to an agent within seconds, and you can also use email or the FAQ question to find a solution to your problem.

The only downside we found was that they have no phone support, but they could easily add this option. So, that is not a reason to be discouraged from playing here.
