FAIR OR NOT FAIR?

I don't know why the sign up bonus of an online casino is so important, cause it seems that's all that's been said about justspin casino. I've been gambling for a long time, and it becomes second nature knowing how games are run, etc. But somethings just not right here. For me, too little combinations, no bonuses. I've been playing book of dead for 5 days now, and have yet to get a bonus. So that already tells me that games are set way to low. Gameplay is the most important part, and it seems that the outcomes are steered much more to the casinos side than usual. So we are at an unfair disadvantage.
