Major bug since the update, if you click too close to the top of the screen cards get stuck and game is unwinnable. Up until yesterday I've played this 1000s of times, it was my favorite iphone app. very simple interface, easy 1-finger gameplay, tough game to win. Suggestions: option to undo last move, also offer a paid ad-free version.

This game has great potential but needs a few fixes: Ads used to show up every few games - a recent change now makes them show up EVERY game and we are forced to wait 5 seconds before we can move on - please give us the option to buy an ad-free version or at least reduce the number of ads we are forced to watch! Also, people have been asking for an undo button for years. This is not a difficult function to provide and a good coder could do this in a matter of minutes. Last, fix the stuck card problem that kills the game.

This would get 5 stars if it had an undo button. Sometimes people play faster than their eyes and miss an important move. On your game, they're done. Makes is frustrating to play, especially if you can win and inadvertently tap the pile or wrong card. You fix it, you get 5 stars and word of mouth recommendations!

If you don’t quite get the card where you want it, the card is dropped. It’s impossible to win, even if you show all of the cards are finished. Say if you drop a king, it won’t show up to finish the game.
