good game but every now and then it doesn't combine them like it"s suppose to. Also after some point yellow stones stop showing up leaving useless gold bars cluttering the screen. Also not sure what you get when you combine 3 diamonds; the view always shows the final product to be what the last final product showed. Which can give ridiculous previews like 3 diamonds making 1 diamond, or 3 diamonds makes an emerald, ect....
Good but kinda broken.
