Popup Notifications
Kosmonaut casino doesn't annoy you with intrusive and unnecessery notifications and popups.
* Popups and notifications are deemed intrusive if they keep opening on multiple pages even after closing, covering the majority of the screen and generally interfering with user experience.

Kosmonaut casino has their website available in 8 languages. You can use 6 different cryptocurrencies to deposit and play and also use a VPN to access the website (tested with ZenMate VPN).


They restrict 22 countries from using their online casino, which is quite a lot, so make sure to check if your country is on the list.


Kosmonaut Casino is easy to use, with a legible layout and a space-themed design with astronauts and celestial bodies (even the loyalty system is based on our solar system!) The website’s navigation makes sense but the game search bar only displays the top 10 results, with no option to display all of them.


Kosmonaut Casino isn’t the fastest to load according to Google but still very fast compared to other online casinos! It’s difficult to find maximum deposit and withdrawal info, as it’s hidden in terms and conditions instead of being listed along with the minimums. All the information applies both to desktop and mobile versions of Kosmonaut Casino.

It is important to note, however, that if you wish to deposit fiat currency and play, you have to give your first and last name, address, date of birth and gender, making the entire process very long.


To pay, you can use 22 payment options, of which 6 are cryptocurrencies. For fiat deposits, you are left with 16 payment options from wire transfers to credit cards. You can deposit in 11 different fiat currencies.


Upon signup, you must choose a main currency, but that can easily be changed later.

User Experience
You have to talk to a bot before speaking to an agent*
* Talking to a bot is not necesserily a bad thing but it does prolong the time for resolving your issue if you must talk to an agent.

Kosmonaut Casino has three support options: a support e-mail address, a contact form and live chat support.


Their live chat is always available on the bottom of the page, but unobtrusive. When you want to contact an agent for help, you first have to get through a bot that pinpoints your question to make the agent’s work easier. The live chat is easy to use, you can also use emojis and add attachments. The agents are friendly and professional with human responses and attitude, and they also provide good answers to questions.
