The thread about one of the recent superior sudokus published in the Sunday times, got me this idea....

The programmers here can generate all type of puzzles.....Why not create a thread where everybody can post their puzzles & then create one huge post with numerous superior puzzles. I will update this post with valid entries. The puzzles will be numbered & will contain the member's name.

Code: Select all: Rules: (They should follow the difficulty level of the Times superior): 1. Unique solution 9*9 vanilla sudoku 2. 180 rotational symmetry around centre point (at least, any Extra would be even better) 3. Maximum difficulty for subsets is Hidden triples (ex. times Superior 8), No Quads 4. Maximum fish difficulty is the X-wing (no swordfish) 5. If a puzzle does not require an X-wing nor a triple to solve it, the puzzle should require a minimum of 3 doubles in order to be in the list. 6. If the puzzle is not solved after reaching the techniques mentioned in points 3 & 4 then it will not be permitted. (XY wings, colouring, ..... are not permitted).... 7. limit your enthusiasm to 15 puzzles per member

I started with one of my own & updated the list as the thread progressed.

This first attempt in producing such a list took just over 1 month to compile. Members of these forums have provided excellent challanging contributions which are guaranteed to provide entertaining symmetrical puzzles. The list has been compiled roughly following the chronological order of each posted puzzle. difficulties are not exactly the same, however they remain within the limits of the Superior puzzles published in the Sunday Times.

You can also find many other contributions throughout this thread which did not make the list.

Ooh, I'll play. The techniques needed to crack this puzzle are not so hard, but it's a nice puzzle, kept me going for a while. I can generate puzzles that require harder techniques, but this'll do for starters. I might post some more, we'll see.

Why restrict the symmetry to 'at least a half turn'? What's wrong with one line of reflection, either diagonal, horizontal or vertical? I'll play by your rules for now.

ab, great stuff.....
The modified puzzle lost some of its reflective symmetry, but is definitely harder...I'll post it as #4

Ruud, 24,000 ..... I thought as well, certainly difficult to choose from & you chose this well

This is probably the best puzzle to come from my generator. And it has the required rotational symmetry.

Your change to my puzzle is definately an improvement Tarek. touche.

I really like Ruud's puzzle too. No singles to start with. excellent. great idea for a thread Tarek.

how are these solved without swordfish?

(edited to drop some W examples because they required swordfish, not x-wing)
here are 14 ordered by symmetry and constraint methods required to solve
these cover all method combinations from my symmetric catalog
the label includes the number of constraint iterations and constraints applied
(F:naked-single N:counted-single B:box-claim T:tuples W:x-wing)

higher iterations => (supposedly) more difficult

Puzzle #001 (tarek) Puzzle #004 (tarek/ab) Puzzle #001a(tarek/ab)

Just pairs and x-wings (dont want to post them here, because they are nice to solve - and there are many)

PS: Nr 10 is my favorite of yours

thanks
I forgot that my solver handles pure x-wings via x-cycles
this means a few of the ones I posted require swordfish
I edited those out

There are 2 with Swordfish, and several have such a low score that, although they qualify, they hardly deserve the "superior" title.

thanks
swordfish entries already elided
I added a few partly to see the difficulty spread from other solvers
your rating seems to require both box claims and tuples to get over 1000
