DON'T DO IT, really really really bad experience, bad customer service, you will lose all your money, they give you a "welcome bonus" but in the end you're playing with your own money. Customer service is really bad, the games weren't working and that's why I didn't had time left.

They do not like to pay when you win a bet. When you play, your money is processed right away but it can take up to 4 hours before a bet is paid out in case you win.

Don't play here, ignore them. I play over a year and you never win something special, it's by far the baddest online casino in the Netherlands. They told me if I play with them I don't have to expect to win something!🤣 That's ridiculous.
