Notation for Sudoku

Notation for Sudoku

Postby OzerTamer » Wed Oct 21, 2020 10:21 pm

Chess notation is a convenient way to keep track of games, so that you can replay them to study tactics, understand mistakes, or impress your friends.

1. Is there any Notation for Sudoku like Chess to show solution steps in text mode which is in use worldwide?
2. I developped one SUDOKU NOTATION to introduce Sudoku puzzle without 9x9 grid and the solution path step by step from beginning to end.
3. Can we review it here and develope more to support more algoritms?
4. It is not sudoku guide book, and does not have solution tricks, but any trick can be explained in text mode.
5. I believe it will fullfil the communication gap between sudoku lover. Most of them are trying to explain tricks and algoritms on YouTube channels. They are too long videos and watching takes time. All sudoku solutions can be written in text mode like Chess Notation.
