Sudoku Rater suggestion

Postby Pupp » Thu Jul 09, 2020 11:58 am

Can anybody recommend a good Sudoku rater? (Online or installed into Windows 10).

I found a good online rater a while back, but lost the link and can't seem to find it. More recently, I could only find a single online rater now, and it rated the worlds hardest Sudoku as "Hard"... which is pretty much useless.

A widely used rater is (the latest version of) Sudoku Explainer:

I'm intrigued by your mentioning the 'world's hardest sudoku'. Are you sure???

I can only guess if the one I plugged into the rater was the world's hardest, but that particular problem has been posted in this forum as very hard, or "hardest". I'm pretty sure the problem I used is mentioned multiple times in this forum, in a variety of threads.

In any event, I only used it as a way to gauge the upper bound of whatever rater I was using. A rater is useless if you don't have a clear idea of what it considers an extremely hard puzzle, and an idea of what it considers "easy", "Medium", "hard", "expert", etc from whatever your using to get sudoku problems. (IE: app, website, book, etc.)

That link you gave me is dead.

Looks as though the link got munched in Mike's post. Here's the corrected link:

That's a dead link too, but I'll scout around google when I get a chance. I"m sure google's web crawlers have found the live link by now.

You don't happen to know how to import problems into 10,000 Sudoku Plus? I emailed the developers. Supposedly I should be able to just open the file with 10,000 Sudoku Plus, but my phone isn't registering that any program (let alone the Sudoku app) can open the file.

The above link works for me.
URL Tagged Link: https://github.com/SudokuMonster/SukakuExplainer/releases
Raw Link: https://github.com/SudokuMonster/Sukaku ... r/releases
I think editing the post messes up the raw link, so you have to keep correcting it.

ER/EP/ED has been the standard for years. It is worth noting that the original Sudoku Explainer [SE] is not up to date.
Methods have been developed since SE was written; including Junior Exocets [JE], MultiSector Locked Sets [MSLS] and others. Sometimes, for example, a JE takes a previously 'hard' rated puzzle and makes it much easier. There are advances by several others too ; notably Denis Berthier, StrmCkr, Robert Mauriès
There are several initiatives underway to revise SE; including Sukaku Explainer by Tarek and another SE by SunnieShine [and others?]
