Maybe I'm overlooking something you've already provided elsewhere. Thanks for providing this set of web pages!

The last few days the 'Jigsaw Sudoku' does not display properly. The Sudoku screen appears, but without numbers or the jigsaw format.
Error message - "can't find sudo".
I updated the Java program but this did not solve the problem.
Help

Longevity is a problem with websites, I'm coming up to ten years, which is unusal. There were several large forums back in the day but they ceased for one reason or another. Of the best that remain, I'd try

I have your Android App for some time now but the latest version 1.69 engine v2.01a sw360 which became available some days ago crashes each time a new puzzle is entered.
The previous version of the App never crashed on me.
A suggestion for the Android App when entering a new puzzle, please allow the entry of clues and also of solutions as is possible on your Windows PC webpage.
Regards

You’d like a distinction between solved and clues on the new puzzle entry? Probably do that
Thanks for the alert!

Load Sudoku: CLICK TO LOADHere is an picture of Simple Sudoku were i painted the ape your solver did not find.
The blue cells are the pair from ape. combination 6,3 cannot be possible because of the purple colored cell. Combination 6,9 cannot be possible because of the triple colored in orange. So 6 can be excluded from the first blue cell.
This picture is taken right after the first found ape.
About the finned x-wing and grouped x-cycles: finned x-wing stands on place 23 where as you grouped x-cycles stand on place 21, so grouped x-cyles gets executed first so finned x-wings will never get found i think.
Outlook does not want me to send emails, so here again.
[edit]
OK the second APE is now showing up in the solver. I detect about 500 more APEs in my test library of 50,000 puzzles (total APE found is around 25,962) so it’s a small but decent increase but there's a 20% increase in time spent looking for APE, but not significant compared to some strats.
Good to be complete (or more complete)
I'll look at the finned x-wings next

Load Sudoku: CLICK TO LOADThis is in the examle of AIC weak link.
And am i right that there is an overlap between finned x-wing and grouped x-cycles, maybe its better to place the finned x-wing above grouped x-cycles.
Can you provide a screen shot of the second APE? Or a scan? Like to see the full pattern.
There is an overlap, but the solver has very different algorithms for both strategies and I've not investigated the exactness of the overlap. But finned x-wing are above grouped x-cycles in the order, no?
Do leave an email address next time
