I think they are worth using if a new player starts small and reads the offer details before playing. My first bonus there was not confusing, mostly because I treated it like extra slot time rather than something I had to rush through. I compared the offer with the games I wanted to try, looked at the UK bonus terms, and from there https://blaze-spins.net/ made sense for a simple first session. That helped me pick a few slots that matched the offer instead of choosing randomly. The bonus did not take over the whole visit, which I liked. It just added more room to play and learn the layout. For a new player, that kind of gentle start feels useful.

Bonuses can be helpful for new players when they are easy to read and do not make the first visit feel complicated. I think the best kind is one that gives a bit more time with the games while still letting the player move at a normal pace. Clear terms, simple slot choices, and no pressure usually make a first bonus feel more comfortable.
