Great Maurice,

so,

Regulra Sudoku =Vanilla
Vanilla + Girandola group = Girandola
Vanilla + 2 main diagonals = SudokuX
Vanilla + 4 windows (r234678c234678) = Windoku
Vanilla + 4 windows (r234678c123789) or (r123789c234678) = Windoku2
Windoku + girandola = Gwindoku
Windoku2 + girandola = Gwindoku2

I have only xy-wing & xyz-wing left to be added to the solver to bring it up to minimum standards....
I have now on ....

Singles
Subsets
Fish

This should be very challenging. Next time hopefully, the girandola will be meeting Wide Windows:D

Girandola X-wing attack !!! (girandola #06 - #11)

Postby tarek » Sun Aug 24, 2008 8:54 am

X-WING ATTACK !!!

The following are superior level girandolas (need one or more out triples or x-wings) .... remember that an x-wing is a 2-fish (2 sectors * 2 Sectors).

The 1st is a TRAINING puzzle, you need to solve it with 1 X-wing only. The rest will need some extra work.

[Solving with 1 x-wing only is needed for graduation]

I guess the FORCE wasn't on the solvers' side on these.....

Will leave them to simmer for another week before revealing the x-wing fleet.

Re: Girandola Sudoku and Star Wars

Postby tarek » Mon Nov 23, 2015 2:02 pm

As the new :D Star Wars is going to be released soon, I remembered posting these girandola sudoku puzzles back in 2008 with a star wars theme, names & x-wings

Girandola X-wing attack !!! (girandola #06 - #11)

(Actually they are a few posts just above this :D :D :D

And a Samurai sudoku posted by me elsewhere with an x-wing photo in the background :D :D

Enjoy (again)

Wow! How did I miss these before? I think I'll start on these as soon as I finish the Ninja (from vfalcone.ru) that I'm working on. Thanks! :)
