What is the definition of "superior" I'm gathering it has something to do with difficulty of required techniques, but I'm not sure of specifics.

I've seen indications on some fora that X-wing is considered a difficult technique, which puzzles me, as I didn't think it was all that hard.

The popular Superior puzzle of the Sunday Times ranked x-wings lower than quads which I still agree with.

Post subject:  Re: 100 Superior puzzles
The words Hard & easy are ver subjective as you know.

When the new wave of sudokus came about in 2005, Newspaper puzzles rarely needed anything beyond doubles.

The "Superior" puzzles published by the Sunday Times in the UK were puzzles that needed triples or an x-wing to solve. These were considered the most difficult in publication for a while.

The term "Superior techniques" came from there. These can be compared to the current APPRENTICE category used here on these fora.

Techniques like quads or swordfish were considered beyond superior :scratch:, techniques have evolved & increased in number, hardenss remains very subjective. The term "Superior" IMO remains unchanged.

Do you know whether the puzzles credited to Ruud in that thread are from his "Superiors" collection, or are they in addition to those? (I couldn't find anything in the original thread where he said one way or the other.)

Ruud Has posted his own superior collection following the exact rules of the thread i referred to.

Ruud was an active member in the Players' forum & YES, the puzzles attributed to Ruud are from the 100 superiors.

The SUPERIOR term pre-dates most current websites & Solvers including RUUD's

Ok, thanks! I already have Ruud's collection of 100 superiors, so I'll just eliminate his puzzles from my copy of your above listing.
