Incorrect Puzzles!

Terrible sudoku app. The interface is nice, but it doesnt generate correct puzzles. Not one of the puzzles I have played had only one solution, and if the puzzles arent correct, whats the point of playing the game? Also, you have to tap the number twice in order to select it for a space, which is very annoying.
