I bought this online and downloaded it. It is a very good game and I enjoyed playing it. Unfortunately, the level with the earthquake tiles does not work. One is supposed to click on the earthquake tiles and the piles are supposed to separate into two separate piles. At this point, a window comes up and says no more matches when I can clearly see matches. So, I am stuck in my quest and can go no further. I contacted IWin repeatedly and they were no help at all; they told me to contact the seller. The problem is a software bug. We contacted Amazon and told them the story, after giving up on IWin. Amazon was very good about it, as they always are, and we got a refund.
