Just after g.r.emlin got sick, I finished my DLX-solver, not with double links but with arrays.
After 2 Xoup games I build in the X-variant.
Now all the constraints (row,col,box,diagonal) are outside de program in a paramfile.
Also suitable for W,A,G,any (halve) JS with or without boxes, and any combination.
Always each house all cells need all digits.
At this moment only for 9x9 grids, but soon for larger grids.
Grandpa doesn't have much time.

It was nice to participate in your sequences. Thanks.
Up for Windoku?

You're very welcome! As for Windoku, I have very few tools to deal with it and I'm preparing another sequence anyway.
