I know that people exist who do notes on sudokus ... I never really did. I also never really did "strike" numbers no longer needed. Saw this by my wife or my father in law.
I dunno how you generate your sudokus. There are multiple ways. I did by generating a full board - which follows the rules (so 1-9 in horizontal, vertical - and within the "group blocks"). Then I remove cells according to the difficulty setting.
Each time I removed a cell the engine tries to solve the sudoku - if more than 1 solution is to found, the cell cannot be removed.
Continue until the desired difficulty level is reached.
Why did I describe it to you? Because this means the sudoku I create are "simple" ones - which are solveable by just going through all cells and checking "what fits" there (there is ALWAYS at least one cell which is only allowing the one and only fitting number). There is no "think ahead 2 steps" cell ("if I put X there, then only Y would fit to the other cell - and so Z must be used in this cell on the top").
And so you normally can solve it in your head, without having to take notes
.
And now without excuses .... when I created it I was a bit in a hurry (did it for christmas for my now-wife) and did not find enough time to add note taking
