All the features I want. No need to go back and forth, cell-number cell-number, to fill in multiple pencil marks. Automatically erases pencil when you fill in a number. Hilites all locations of the number you're currently working on. Puts pencil marks in keypad-placement instead of crammed one after another. Validation if you think you've messed up, and Hints if you really need it. Makes it too easy, I suppose, but I doubt if I'll go back to any lesser version. Needs higher levels.

Really good concept of use, but a few serious flaws. First, all games outside "extreme" are super easy. Second, it has a bug such that sometimes a pencil mark gets erased during use, and I know this is not my error. Third, the splash screen is way too lengthy, making it an advertisement. I paid for this, which means no ads: that should mean no ad for genina games. Last, for speed, it needs to change all entry to "flip" the state of prior entry rather than forcing the use of "undo".

Pretty straight forward Sudoku, ads are visible but do not impact game play so much. Others I've played obnoxiously threw ads up on the middle of play disrupting the game and making them unfun. I click on the ads here when I decide I have an interest, not because I have to. 1 other kudo, the game seeks to make you a better player, but if you're peaked out, it will lower the game to one you're more likely to solve in a reasonable time. Thanks, I really appreciate this.
