Personally, I think its the best SS app on App Store :)

I liked how:
-I can tap a card then it would automatically fly to its vest spot
-I can play my background music while playing the game
-the design was nice
*the winning rate was displayed (what I couldnt find on other apps!)
-I could see my statistics
-the movements were fast
-no unnecessary effects
-the cards were big enough to see (some other apps have had smaller cards)
-no bugs visible (as far as I have played)

What I think can be fixed:
-this may be unnecessary for some people, but a button to show the "hint"?
