36x36/64x64 sudoku puzzles?

Postby udosuk » Sat Sep 09, 2006 8:55 am

This must have been discussed before, but with the 26 letters & 10 digits it'd be quite nice to make 36x36 sudokus... Better then 100x100 for the multiple digits make it clumsy to represent... Here is a solution grid (very canonical one)...

And, with caps and small cases plus the 10 digits plus the 2 symbols * & #, we could also make 64x64 puzzles:

Not that these solution grids are of any interest... But would anyone like to make some puzzles with these dimensions?

I used { _ $ } as the 2 extra because * is sometimes used for borders and # for comments

Well, here's a 36x36 for starters. Locally minimal with 48% of clues removed, and double-mirror symmetry. I need about 1 minute to produce one of these, so there's no problem making more. 64 x 64 to follow.

Regards,

Mike Metcalf

As promised. This took 50 minutes, is locally minimal, with 41% of clues removed. I used = and ? as the odd characters.
