In addition to my long experience that I have gained in terms of online casinos, there are strict criteria that I use in my CosmicSlot test. First, I'll get an overview of the entire game selection. I'm testing the mobile app, checking the betting and table limits and RTP values. Then software, website and customer service. You will find out my CosmicSlot review at the end.

The CosmicSlot range of games: Many manufacturers and a top selection

Over 3,100 casino games from 37 different manufacturers leave no doubt that you will find something suitable. In addition to the quantity, the quality is not neglected either. All important game categories are available and you can draw from the full. A detailed overview follows.

The range of games in numbers

My CosmicSlot experience in terms of game selection was excellent, with the number of slots naturally predominating. You will find all topics. Starting with classic fruit slots up to the most modern video slot machines. There are also many jackpot slots, but the top game Mega Moolah is missing, for example.

Online roulette and blackjack online are also represented. However, some compromises have to be made here, because the selection is rather manageable. Nevertheless, you can fall back on some variants of the popular casino classics. Unfortunately, there are only a few video poker games.

Also represented are some table games such as Baccarat, Sic Bo or Casino Poker Games as well as Keno. If the selection of table games is not enough for you, I recommend you take a look at the live casino. There you will find plenty of tables of classic casino games in many variants.
When I took a look at the provider's game developers, I noticed that only NetEnt is represented by the long-established manufacturers. But also big studios like Pragmatic Play, Quickspin or Red Tiger can be found, according to my CosmicSlot experience. Over 30 game developers offer you top entertainment and first-class quality.

Live dealer games

My CosmicSlot Live Casino experience was very good. Four game developers lure with their live games. Ezugi, SA Gaming and Asia Gaming offer the best entertainment. The market leader Evolution runs everything it has. Great roulette and blackjack variants as well as game show games like Deal or No Deal, Crazy Time and Dream Catcher await you.

All four providers do not show any weaknesses when it comes to the transmission of live streams in HD quality. So you are spoiled for choice. In my test, the live casino did extremely well, which is reflected in the CosmicSlot rating. Variety is guaranteed, because you can switch from one provider to another at any time.

The CosmicSlot Mobile App - play on the go

A mobile casino app is necessary to be able to use online casinos on the go. The provider goes a way that many other online casinos also go. He has optimized the games and website for mobile use. Thus, downloading a CosmicSlot app is not necessary.

You simply open the browser of your mobile device, visit the casino and can play directly in the browser. Whether iOS or Android, the view is adapted to the screen size. This gives you the opportunity to use the virtual casino on the go. However, a good internet connection should be available.

A look at the betting limits

I also looked at the betting limits in the wide range of games. Only in Blackjack do you have to invest at least €1 to be dealt the cards. You can bet a maximum of €5,000 there. The limits for the slots are between €0.10 and €500 per spin.

Beginner-friendly limits were also chosen for the casino classic par excellence. You can play roulette for as little as €0.10. The maximum bet is a whopping €5,000. Thus, the table and betting limits are suitable for both beginners and experienced players.

The payout percentages in my CosmicSlot experiences

A look at the payout ratios, which are referred to as RTP values (Return to Player), did not reveal any major surprises, with the exception of one special feature. As a rule, the video poker games have the best payout values. Due to the small number, this is not the case here according to my CosmicSlot experience.

When it comes to RTP values, blackjack takes the top spot. Most slot machines have payout rates around 96%. NetEnt's Blood Suckers slot achieves a top score of 97.99%. Overall, the payout percentages at CosmicSlot Casino can keep up with the competition.

Return to Player (%)

*Arcade games are not offered.

Due to the existing gambling license, ComicSlot is obliged to have the RTP values checked by independent test laboratories. This ensures seriousness and fairness in the game. Overall, the virtual casino has a payout rate of around 96%. A value that is achieved at many online casinos.

You can usually find the payout rates for each game in the Help menu. When it comes to roulette, you should note that the American Roulette version has worse RTP values. This is because this variant has the additional double zero that is not present in European or French roulette.

Software & website in detail

The website of the provider is attractively designed and clear. During my CosmicSlot review, I noticed that the game categories are named a little strangely. The dice symbol refers to board games, but of course table games are meant. Under the 7 symbol are the slots which are referred to as slots.

I'm sure this will be corrected soon. However, my CosmicSlot experience with the website has been good and user-friendliness and functionality is a given. You can log in or register at the top right. Links take you directly to the games, the live casino, a shop and the casino promotions.
The website and software are state-of-the-art, which is also confirmed by the fast loading times of the games. Many games are also available as demo versions. All can be played directly in the browser. A download is therefore not necessary. The gameplay works smoothly and without technical problems.

The search function is also very helpful. You can search directly for a specific game, or display the games from individual providers. You can also search for generic terms such as roulette, but you will then also see the live games. Nevertheless, you get a good overview and can switch directly to the game.

My CosmicSlot experience in terms of game developers has been good. As you can see in the table, the provider's portfolio consists of a good mix of well-known and not yet so big game manufacturers. The quality of all games is on a high level and the graphics do not leave much to be desired.

Who is behind CosmicSlot Casino

The company Altaprime Limited is specified as the operator of CosmicSlot. The company is based in Cyprus and is a subsidiary of Altacore NV, which is headquartered in Curacao. The company registered under number 151002 is well known in the industry and operates several other online casinos such as Stelario Casino

The All Reels or the Dozenspins Casino also belongs to Altaprime Limited. All casinos operated by the company have good portfolios and offer you games from many different game manufacturers, with which a large game selection can be guaranteed.

Company Profile: Does CosmicSlot have experience in business?

As you can imagine, the company that runs ComicSlot has a lot of experience when it comes to online casinos. When it comes to player protection, customer service is always available to set desired limits or implement other restrictions such as self-exclusion from gaming operations.

The CosmicSlot Customer Service

The CosmicSlot customer service will be happy to help you with any questions or problems. Contact can be made via email, telephone or live chat. German-speaking employees are also available 24/7. During my CosmicSlot test, my questions were answered quickly and competently.

I can recommend the live chat as the quickest way to get in touch. The employee was there quickly. A telephone hotline is also available to you. However, the call is not toll free. Unfortunately, there is no FAQ section that gives you answers to the most frequently asked questions.

How to contact CosmicSlot Customer Service:

Live Chat: Available 24/7
Email response time: 1-2 days
Phone: +35725654149 available from 9:00 a.m. to 11:00 p.m

security and license

Security and seriousness are guaranteed by an EU-wide gaming license. In my CosmicSlot experience, I found that the provider is licensed by the Antillephone eGaming Curaçao authority. License holders have to comply with various requirements.

This includes, among other things, checking the random number generator by independent test laboratories to guarantee fairness in the game. Furthermore, the CosmicSlot website must be secure and personal data and financial transactions must be protected with modern encryption technology.

Bonus points from the test

In this section of my CosmicSlot test report, I award extra points for the tested provider. So there are full points for the casino actions. In addition to the lucrative welcome bonus for new customers, there is also weekly cashback and regular reload bonus offers.

There are more points for the special games like bingo or keno, because these are not found in all online casinos. As a result, CosmicSlot increases its attractiveness and offers its customers more variety in the game selection. However, the casino newcomer has not yet received any awards.

If you verify your email address and mobile phone, CosmicSlot even gives you 10 free spins. However, my Cosmicslot experiences have shown that there is no real VIP program. This is of course a pity, especially for loyal players of the virtual casino.

The term shop hides a shop where you can exchange coins/loyalty points for free spins or bonus money. You get the Loyalty Coins by playing with real money at the casino. From 40 loyalty points there is already a €10 bonus or 20 free spins.

Conclusion: CosmicSlot - Great game selection and many casino promotions

My CosmicSlot review is extremely positive. The extensive game selection with a good mix of well-known manufacturers and smaller studios offers great variety. The live casino is in no way inferior and four providers are vying for your favor. Website and software are excellently optimized for mobile use.

In addition to the attractive bonus offer for new customers, CosmicSlot also has many casino promotions for its customers. With the loyalty program you can exchange points for bonuses or free spins. All in all, a thoroughly convincing performance with an end result that is impressive.

Significant Strengths

  • Great game selection
  • Top Live Casino

Minor strengths

  • Lots of casino promotions
  • loyalty program

Significant Weaknesses

  • No VIP program
  • Few video poker games

Minor weaknesses

  • No FAQ section

However, my CosmicSlot experience also revealed room for improvement. The selection of video poker games is not particularly large and could still be expanded. So far there is no VIP program and I couldn't find an FAQ area either. If improvements are made here, there is potential to catch up with the best German online casinos.
