I contacted support and instead of usual waiting time for 15 minutes, support was professional and fast so maybe they have improved some things. Support told me that I was eligible for it, so after that I went to cashier, made deposit and claimed bonus. For my 25$ I received 106.25$ bonus and with 131.25$ balance I would need to wager little under 4000$. That is quite a lot for the maximum cashout of 250$.
I started to play Aladdins Wishes with 1$ bets per spin, since I had a nice balance amount. Soon I received a bonus round, but from my 3 picks I only got multipliers, not free spins. I played for about 20 minutes, but I just couldn't get over my initial balance, it only became smaller and smaller. When it reached around 40$, then I went to play Count Spectacular. I played with 0.50$ bets but the game was absolutely dead and within an hour my balance was gone completely. I received only one bonus round and it nearly paid 10 x bet size. It was really upsetting.
Overall I had a decent time at Lucky Spins casino but I am sure that after this time I won't be depositing there anymore, I will only play there with no deposit bonus, if I receive one sometime. I can see that they have improved their customer support and that is good, but I think that terms for this bonus are little odd, giving such generous bonus amount and making a max cashout of 1 0x deposit. I wouldn't recommend neither this bonus or this casino overall.
