Thoughts on Rich Prize Casino's no deposit bonus?

I’ve been hearing a bit about Rich Prize Casino offering a no deposit bonus, and I’m curious if anyone’s given it a shot. Sounds like an easy way to test the waters, but I’m wondering if it’s worth the time versus sticking with the best real money casinos.
From what I’ve seen, they often promote progressive jackpot games, which is always tempting, but I’d like to know if the bonus is actually usable on those games. Also, how strict are they about following instructions when it comes to claiming the bonus and using it? Some casinos get so nitpicky about their casino promo codes that it feels like jumping through hoops just to play.
If you’ve tried out the Rich Prize Casino bonus, what’s your take? Is it straightforward, or one of those deals that only looks good on paper? Let me know if this is something I can use without too much hassle.
