What's the deal with YoYoBet promotions?

I've just signed up to YoYoBet, and I'm seeing loads of promotions like the early release on BC Game and bonuses that can go up to €500. I'm a bit lost on how these actually work. Do the bonuses have tricky wagering requirements? And what's the best way to take advantage of them without getting caught out? Anyone got any tips or experiences they can share? Also, are there any standout promotions I shouldn’t miss? Looking forward to your insights!
