My Personal Experience - Cosmo Casino

When I joined up at Cosmo Casino I was immediately impressed. The website was professional and ran smoothly. Entering of personal details and then making my first deposit was so quick, that I was playing my first game in two minutes! I tried my luck on the big game Mega Moolah, with my 150 FREE SPINS! Sad to say that I didn't hit the Mega Jackpot, but I did have some good fun playing! Cosmo also has all my favourite slot games like Immortal Romance and Game of Thrones, as well as Live Dealer Blackjack and Roulette!

Since Cosmo Casino is a member of the Casino Rewards Group, I get the benefits of earning VIP points and claiming them at any of the member casinos! I also receive frequent promotions and bonuses from the Loyalty Program which is a welcome change from some other casinos where you can play for ages and never receive a bonus. I have found Cosmo Casino to be an excellent online casino experience and the BEST in Ireland.
