I've received a lot of interesting comments and questions from Sudoku fans over the last few years and this page
is where I try to answer them. I'm also directing Str8ts feedback here. Please feel free to drop me a note on the side of the page. Or you can email me directly at email@example.com.

I came here to get some informations about the Setti-rule of Str8ts. Your article helped me a lot to understand it, but I don't see it exactly in your example with "Extreme number 31".
You say, that you are sure, that in every column there has to be a six. But column 9 would work without a 6 right?
Maybe I don't see it but this confuses me.
Anyway, thanks for all the hints and tips on this site!!!
Sorry for such a lame answer!

Did I miss something?
That uses all strategies. Ticks are for the solver only. Could be something I should make a feature

There is a X wing in this puzzle for 4s. It is not recognized

I suggest you use "Player >" to send the puzzle to the player which does allow candidate editing
And if you get stuck "send to solver"
The solver will still ignore your candidates since it needs all logically present ones, not just the ones important to you. But you can step from that point to discover the strategy

Sorry, I need help again:
When I want to print a str8ts puzzle, the black squares are not there. How can a get them?
Thanks and have a nice day.

In the previous version, as soon as all the cells were filled in, the number of errors would be reported.
Many thanks for letting me know, appreciated
