The same thing I tried to activate 10 free spins of lady wolf moon slot for registration with a promo code, but after confirming my mail, it didn't work for me, including, perhaps, protection against multi accounts works if it exists, although I registered for the first time, it doesn't matter.
We can get not all the bonuses that have been given by the casino, even though it's just a free spin bonus.
Every casino must have some of their conditions for being able to provide a promo bonus. Maybe you need to try it another time because there are definitely a lot of gamblers who are also trying to get this bonus.
The luck factor also has an effect there. If you are lucky, maybe you can get those 10 free spins. Even with free spins, you can win up to quite a lot of profit.
But here only a few gamblers can benefit from the free spins bonus results.
Indeed, in order to try to get a bonus in the form of free spins, you need to hunt for it, but it is not possible to do this periodically, if there were notifications to the mail it would be much easier, but those who are looking for those think they will be able to get something in the end.
