I'm interested in an online casino that offers adequate cashback, not 2% with a bunch of conditions. Sometimes you're unlucky, and it would be great if at least part of your losses were returned. Are there any sites where you get at least something back without begging?

Yes, I understand. I play at http://kingschancecasino-au.com/ and I can say that their cashback really works. On weekends, they return up to 10% of what you lost during the week, and this is without any extra hassle. The money comes automatically, without applications. This often helps out - you can win back or at least return to the plus. Plus they have VIP levels - the longer you play, the higher the return percentage.
