I will try to finish this before the end of this year.

I have to pass on this one, because I don't see how to define the Jigsaw pieces per grid.

The solution is correct. Well done.
I think this particular jigsaw samurai is easy to generate, by generating 5 separate jigsaws as per definitions, and ensuring these constraints:
g1r8c9 = g3r2c3, g2r8c1 = g3r2c7, g4r3c9 = g3r8c3, g5r3c1 = g3r8c7
g3r1c1 = g1r8c6, g3r1c9 = g2r6c1, g3r9c1 = g4r4c9, g3r9c9 = g5r2c4

On the same site they have also a gattai-8 grid version with the same pattern.
How do you start solving this by hand? Any suggestions?
In case of the gattai-5 I started with the central grid, which can be viewed as a normal sudoku and try to connect it with the top and bottom grids.
With the gattai-8 variant I expect additional difficulties because there are 2 central grids.

You start by solving the grids with the most givens. And in these puzzles you can use law of leftovers on the overlapping boxes, transforming them into normal boxes.

Can you post a more precise hint. I can't get started.

Start with naked/hidden singles:
g1r8c7=1, g7r8c2=7, g8r7c9=5

by **creint** » Tue Dec 22, 2020 9:02 am

Easy first singles
4g1r3c9
5g1r5c9

5g2r5c6

7g4r1c4
7g4r4c9
6g4r6c5
7g4r9c6

8g7r5c5
2g7r6c6
7g7r8c2

3g8r3c5
5g8r7c9

Continue at grid 2 and 7 and then 1 and 8 and then center.

Looking at the definitions posted by 1to9only which give the correct colours in each grid your SiSeSuSe version of November don't process the gatai-8 correctely. The gattai-5 works. So the rating in grid 3 of 4.5 which is a uniqueness rule I presume confirms my hypothesis that it might have to do with the bug in your November version which empties cells having no more candidates in case of uniqueness. Can you run it in your latest bug fixed version and post if it passes?

by **Hajime** » Tue Dec 22, 2020 9:17 pm

There is a unique solution for the Samurai based upon the code of 1to9only
Naked/Hidden Pairs/Triples and Quads are needed and also Pointing/Claiming.
SiSeSuSo searches for Pairs/Triples/Quads in one subroutine and does not stop at the first elimination.
