I am beginning to wonder about Doralogic Mahjong. I downloaded the free game on my iPad but I quickly found that there are only a few free Shuffles (unlike other similar games that have unlimited free shuffles). So, like an idiot I bought Shuffles - only to find that I received nothing and that Doralogic and Apple are ignoring my emails and in App messages. So, it looks like this is a rip-off.
