Thanks for these!

Busy with stuff just now (same old, same old) but I am looking forward to some serious P&P headscratching when I can tear myself away from current obsessive focus ... 8-)

Hello

Thank you for sharing these puzzles, but I wonder how you know the difficulties of these. If l remember correctly SE doesn't have this function. :D

Could you share this software with me^-^ :) thank you very much

My solver still can't solve those with tactics but there are some hidden constraints in those puzzles, using those could decrease SE rating. How much decrease is still unknown.

The changes to SE (from using 3x3 blocks to irregular cages) has been going on for a number of months, as time permits. It is usable, but not finished.

I can probably tidy up the code a bit for a pre-release (with no support!), maybe next week.

Postby 1to9only » Thu Aug 27, 2020 8:36 am

This is a pre-release (no support!) of my SudokuJigsawExplainer - download here: here.
It is usable, but not finished. In testing, it has solved (some of) these jigsaw puzzles:
- The Jigsaws at: https://www.sudokuwiki.org/jigsaw.htm.
- The Daily Jigsaws at: http://www.sudocue.net/jigsaw.php.
- The 9- and 8- clues Jigsaws at: http://www.bumblebeagle.org/dusumoh/9x9/index.html.
- The Daily and Weekly Jigsaws at: http://www.sudoku.org.uk/Jigsaw.asp and http://www.sudoku.org.uk/WeeklyJigsaw.asp.
I have not tried any of the Daily Jigsaws at: https://www.sudokuwiki.org/Daily_Jigsaw_Sudoku.
