Windoku X (NRC)

Postby evert » Sun Jan 20, 2008 5:33 pm

Hi all,:D

I'm working on combining windoku (NRC) with two diagonals (windoku X).
If anyone did this before I'd be interested in some of your examples.

Here's one:
Code: Select all
060007000
800030009
009000000
034800000
000000000
000006500
000000000
300000004
100079000

(I didn't yet add the interactions between diagonals and boxes/ NRC-boxes.)

Evert

I've been collecting impossible constraint combinations. X interacts well with WinDoku but if you add the Anti-kNight constraint there is no solution.

H3lix gives an elegant proof of why not at:

I'll give this one a try.

What about Windoku - AntiKnight (no X)?

I found some Windoku X puzzles that actually need interactions between the boxes, NRC-boxes and the diagonals:

I'll give the later ones a try

WinDoku anti-kNight (W AN) works but WinDoku Anti-kNight Anti-King (W AN AK) does not.

Your first one solved on doubles and singles if you use all the interactions.
