This Sudoku puzzle creation enables a much faster process in figuring out a hard to very hard puzzle versus having to separately write on paper. I had a super-hard puzzle from The Week magazine that I know through the manual method would have taken an hour to solve. I solved the puzzle in half the time as it’s much easier to visually see all the possible numbers as well as patterns that helped me eliminate numbers within a row, column or box!

You should add ability to highlight all of pencil mark number when that number is selected. For example if I select no. 1, now all off numer 1 are highlighted but not pencil marks of numer 1 in all fields that I have possible 1s. Beside that, great app All the best from Serbia

So glad that I found this app. I use this to compete with my friend. Before we have to solve the sudoku on paper. Now it’s much more easier to do it on phone, save pencil and paper haha. I have a suggestion for the next update is that there is a feature to highlight all the same number in all cells, even in the notes, when you select a number. Right now it doesn’t highlight the number in notes. Kudos to the team. Thanks!
