Makes one work one’s brain cells function

I like this Sudoku Version. I like touching one number and having all “like” numbers highlighted at once. I like that when you enter a wrong number it is NOT colored immediately to indicate it’s wrong. You must do that individually and only if you are looking for that information. What would, in my opinion make it better; When you eliminate a number, all other pencil marks of that same number vertically, horizontally and within that same block would automatically self delete. Also when deleting pencil marks, it would be helpful to not have to pick the delete button after each pick to delete another, but rather once a number is picked you continue picking numbers you wish to delete until you are done and only then would you hit the delete key. (This BTW would even be less necessary) if the above suggestion is adopted. One other suggestion might be to have the button that adds all the pencil marks at once to be a toggle switch which would when hit a second time turn off all the pencil marks. Hence the pencil marks are displayed or not displayed at the users discretion. Thank you for the opportunity to make “User Suggestions”. I gave this version a rating of 4 stars. And on a scale of 1 to 10, I would rate this Sudoku an 8 and with my suggestions, a 10 or 5 star! It would vastly speed up ones ability to solve a given puzzle.

Love that I can add notes easily and alter easy. My only complaint is that I don’t know how to save progress on a game once started and not completed. Im a super busy mom so I play in spurts but if I need to exit and can’t save my progress but once I won’t keep playing. I have to be able to jump back and forth.
