Thanks for your comments. Let me clarify something more. First of all, this is not a computer programming steps. It looks like computer programme, but it is not. It shows steps of solution one by one. It is just for writing on the paper. Secondly, it is not introducing any solution tricks, methods, ...

Your answer does not address my complaints. If you deduce R3C5 = 3 or 5, you don't know that both are right -- so you have to guess. (There is no way to deduce that both numbers are right! You most likely assume that your logical skills are insufficient at this point.) I thought at that point, 3 or...

If there are two solutions, there is no logical way to decide which part of the solution path the solver should take. The solver must guess an some point. For example, you deduce that R3C5 must be 3 or 5, but since 3 leads to the first solution and 5 to the second one, there is no logical way to de...

How? I could not see any contradiction on two propositions.
I will be happy if you can explain.

I think we should have general WPC/WSC style puzzle rules/definitions/guidelines that apply to all, or whole genres of puzzles. I'll kick off with a few... - All puzzles must be logically solvable from the information given. - All puzzles must should have a unique solution. The main exception being ...

Thanks for your comments.

I have developped a notation for Sudoku similar to Chess Notation. This will provide a common language for sudoku solvers and setters. The notation uses text and symbols to show THE SOLUTION PATH from beggining to end. I would like to open it to discussion and get advises to serve better. SUDOKU_Not...

"All puzzles must be logically solvable from the information given" -- What 'logically' is depends on the abilities of solver. For example, some of the more complex Sudoku solving methods - e.g. color chains - can be seen as trial & error by an average solver. Any "what if" ...

I advice to follow a youtube channel named cracking the criptic.
You can find a lot of sudoku solutions videos.

Meanwhile I developped a notation for sudoku. I am trying to make it worldwide language of sudoku splver and setters.
