As a collection of unique solitaire games I would say this package is quite excellent! While I do admit I am not a solitaire connoisseur, most of these variations I had not heard of and I found them quite enjoyable and a few of them quite challenging. Each game has a distinct theme/ style that suits its game respectively with nice music to boot. Their could be a bit more tracking of stats and such, all it tracks are wins. I thoroughly enjoyed popping in to this game when I had some time to kill and might continue to do so!
