Extreme Sudoku Variants
The last time I tried this it did not go well. I found out my difficulty rating system, well - sucked. I have gone yet further down this rabbit hole in the past several days making it better. I have mirrored to some extent the Sudoku Explainer(SE) difficulty ratings system for this sudoku generator. I think it does pretty good. Now lets see what you think.
One caveat - sudoku.coach seems popular here. They however do not follow the SE rules exactly. Thats why you see ~SEn.n for their ratings. The tilde means not exactly in this case as they use a proprietary rating system based on SE. So you may see some disparity if using them. They also do not rate variants as far as I know. Neither does SE allow for variants rating. Maybe I need to add a ~ to mine as well?
As usual google drive - https://drive.google.com/drive/folders/1yLv7v--tPxs3Dm_CfIDXdzCFLcc6qOfs?usp=drive_link
There is an Easy, Medium, Hard and Extreme pdf there in a folder. Enjoy. Let me know if they are any good.
