CosmicSlot Casino, like most gaming brands, has a well-trained customer support team available around the clock to assist customers with their issues, questions, or complaints.

Compare CosmicSlot to Similar Casinos

This section of our review will compare CosmicSlot Casino with two other casinos in Ireland's iGaming market, JustBit Casino and Spinz Casino. JustBit Casino offers its players a live chat service where customers can directly contact the support team when they run into issues, unlike CosmicSlot, which can only be contacted via phone and e-mail. 

JustBit does not have a wagering requirement too. CosmicSlot triumphs this casino with its huge welcome bonus, phone support, and a larger number of bingo games. A better game licencing authority licences Spinz Casino as opposed to CosmicSlot’s Curacao e-gaming licence, and the casino has a round-the-clock live chat feature

CosmicSlot Casino takes the edge with its extensive payment method list, crypto payment options, and a larger number of games. If you are in search of a casino that provides lots of speedy payment methods, CosmicSlot is your best bet.
