Do not EVER purchase anything in this game. If you do, you'll have fun for a few weeks and then you'll never win again. I purchased diamonds for the VIP because I like the aesthetic of those slots - I won and lost off and on for a few weeks. Now I haven't won for weeks and the ads and "coupons" are increasing. If I wanted to really lose, I'd go to Vegas. This is supposed to be a fun game - losing pretty much every spin for two weeks is not fun.
