Registration bonuses

I've heard about registration bonuses, but I'm afraid there's a catch behind them. Is it worth paying attention to this at all?

 

I also had my doubts when I saw the offer from https://x.com/wildzcasino — a sign-up bonus. But I decided to try it, and in the end I was satisfied. Everything turned out to be extremely honest: there were no hidden conditions, everything was clearly outlined. This was a pleasant surprise, because I expected a catch, but I got only a plus to the game.
