The x50 wagering requirement is pretty high, many other casinos have lower wagering requirements, so I doubt anyone will try this bonus. Especially when we consider the url=https://jokerbet.biz/#category=bonus]List of slots[/url] we can play... I don't remember hearing about Kayot Games, Appolo Games, and some others. And for sure I haven't played them, I don't like any of the slots images. So this bonus doesn't seem attractive at all.

If you wish to attract players you will have to make some changes... good luck!
