Once you beat the first mine you pretty much beat them all. Don't spend any money on this game because you just be wasting it. If you want diamonds just wait until your free spins come available 70% of the time you get between 2 and 4 diamonds. You could easily blow a fifty dollar bill just getting one mine to collect automatically. And if you don't respond and leave a comment they will harassing you all through your game. That's why they got me telling you the truth
