Summary: Excellent and addictive game; developer is responsive. Details: I am not much of a card player, but I enjoyed the lite version of the game so much that I decided to purchase this version. I have sent new feature requests to the developer (via the "About" panels button), and the developer actually responded, and the features eventually got into the product. Because of that, the "Best Scores" section has improved dramatically from keeping your own "top one" score to keeping your own "top ten" to also including a worldwide "top 25" and worldwide "top 50". Impressive continuous improvements. The developer seems to be responsive to others as well, as other new functions have shown up. I agree with one reviewer that this 1.7 version of the game sometimes crashes as it is attempting to submit your top score to the server. However, that has only happened to me twice in about 30 tries. And, based on my experience with this app, I suspect this problem will be addressed by the development team. They (or he?) seems to care about this product. Your $$ here is a good long term investment. Just my opinion.
