This app has ads. OK, fine. At first, the ads were on the side of the game, and they would display and change on occasion as you play the game. Recently, in addition to these ads on the side that did not interrupt game-play, on occasion, without warning, the entire screen would change from the game to an ad, while trying to play the game. This is completely ruining the game play. This interruption breaks the rhythm of the game, and if I'm about to click on a box to put a number in it, the click instead opens a browser window on the advertiser. I'm sure this accidental click through is causing the advertiser to believe they are getting more accidental clicks than intentional clicks. I am about to uninstall this game and find a different one. The hyper-intrusive ads take the fun out of the game, and I believe the methodology of these ads is borderline fraud.

Good except for some reason I misread numbers that I do not do with other Sudoku games

App is quick, like the way you are given a wrong sound for a mistake. Makes you think in advance. MArge

There is no undo feature, and filling in a square does not update the notes by removing the number from other noted squares. Basic gameplay components are missing!

I'd like to be able to cancel a game without playing it out to the end.

Like it a lot. You get to compete against a clock.

Too many multiple solution puzzles. Auto removal of pencil marks when number is placed would be nice.
