I bought Belatro and Zachtronics solitaire a few weeks ago, more or less on impulse. The Zachtronics was disappointing primarily because the UI is too small on my iPhone, and I have old eyes. Belatro is great.
I'm something of a Solitaire addict. In addition to Belatro, the Microsoft Solitaire Collection is the only game on my iPhone, and I happily pay Microsoft $10 a year because the design is the most comfortable for me. Klondike soothes me like nothing else, but it's nice to be able to put a little variety in the game for me with FreeCell, Pyramid or TriPeaks (I'm not a Spider fan).
You should try out FlipFlop solitaire by Zach Gage if you haven't already, definitely a fun spin on the solitaire concept and the game plays very smoothly.
