CosmicSlot Casino Review

CosmicSlot is a new venture of Altaprime Limited, a European company known for its impressive projects, such as All Reels and Dozen Spins. It’s time to fuel up your rocket and blast off to the CosmicSlot casino universe.

What’s good about this online casino?

It’s licensed by a robust regulatory body, showcases more than 3100 of the best online casino games from 25+ iGaming providers, and not to forget its splendid bonus offers. It’s an outstanding gambling platform with 24/7 customer services and multiple payment gateways, including new and trusted options. Interestingly, the casino website rewards their players handsomely by inviting them to their exclusive VIP club. 

Let’s talk about the aesthetic! This is one of the top online casino sites when it comes down to themes. The space theme is eye-catching, and the homepage looks quite busy compared to other online casinos that opt for minimal designs. We were impressed that every information players like to know about a website is available on the CosmicSlot homepage. A banner displaying the bonus offer, games section showcase popular slot titles, and the activity section will give you a rundown of all the hot happenings on the site. It includes the biggest win of the month, last win and total jackpot (at the time of writing, it was €5,000,190).

Things become more personalised as you proceed from displaying your recently played casino games and searching by your favourite list. However, it’s not something new to experience, but it’s a nice touch that enhances the player’s casino’s gaming experience on the casino website. Even though some players might think that the homepage is a bit cluttered, overall, the site is quick to respond and well designed, with all features organised for easy navigation. The menu opens up as a side panel displaying all the main features.

CosmicSlot is an international gambling platform that translates websites into 10 languages for players’ convenience. In this review, let’s find out what other bizarre features the site has in its arsenal.  

Unfortunately, this casino doesn’t accept players from the UK.

CosmicSlot Casino Bonus Wagering Requirements

Avid players always read the fine prints of bonus offers before opting in, and to be honest, CosmicSlot is very clear with its terms. If we consider the wagering requirement of the welcome offer, it’s a mixed bag. 

You have to wager your free spin bonus winnings 40x, whereas deposit match bonuses require 35x wagering. The maximum wagering amount for players is €5 and the validation period is 10 days.

The game weighting to fulfil wagering requirements varies from one casino game to another. Slot games contribute 100% towards wagering requirements. However, table games, roulette, blackjack, video poker, craps and Baccarat contribute 0% towards wagering requirements.

No Deposit Bonus

This is one of the best bonuses in the gaming industry. Not many operators give new players the privilege of getting a no deposit bonus. Unfortunately at this moment in time, there aren’t any no deposit casino bonuses available to CosmicSlot Casino players!
