I gamble on roulette, dices and slots, but I gamble most on roulettes. Slots are less fun for me while roulettes are more fun for me. For the casino game that is the best for me, I think this should be about preference. The games that you love playing should be the best for you.
I recently tried gaming on Crazy Time, and I loved the way the host deals with the users; they keep them engaged and thrilled.
