Casumo must be one of my favourites, since the layout is playful but clear at the same time. The cashouts are super fast aswell. Last but not least their site is one of the moste stable, lag free sites i know so far. big thumbs up!
One of my other loved casinos is Rizk. All the wager free spins you get, the game selection, a really easy and nice design, make it shine. Also my verifications was pretty fast for me.
Casino Calzone has a really nice feature, where you collect a currency. You can save it up, until you have enough to buy spins for the Calzone wheel. I have had a lot of fun with the freespins resulting from it, and also some nice cashouts! Its just adds extra value to your gambling, which is unique and really cool. Also, the cashouts are really fast and the live chat was always helpful when i had questions.
