DEFCAB
(Published on 8. September 2021, 15:00 by PetLov)
I decided to call them DEFCAB lines. DEFCAB is of course a set of consecutive letters not in alphabetic order.
It seemed appropriate to me since the opposite, Renban, is not spelled with consecutive letters. The n in renban even repeats which is horrible.
The colour code for the DEFCAB lines in F-puzzles is #DEFCAB.
Normal sudoku rules apply.
Digits on an arrow must sum to the digit in that arrows circle.
The red lines in the grid are renban lines which must contain a set of consecutive digits in no particular order.
The green lines in the grid are DEFCAB lines which must contain a set of non consecutive digits in no particular order.
The opaque grey squares must contain even digits.
Solution code: Row 4 and column 7

Hello!
Of course henrypijames is right.
It is in fact nabneR lines.
So much for trying to be original :-)
Regarding the name that is just a reflection of my twisted mind.
Gonna have a go at Zetamaths puzzle now :-)

Very fun puzzle! Thankyou :-))
henrypijames is right. I remember Simon with a big knot in his tongue while pronouncing "nabneR".

Isn't this the same as the "nabneR line" introduced by Zetamath recently (in a truly stunning puzzle)?
"DEFCAB" seems to be a really misleading name, since these letter are actually consecutive, but the digits must not be.
I didn't like "nabneR", but I like "DEFCAB" far less.

Zur Klarstellung: Eine DEFCAB-Linie enthält lauter Zahlen, von denen keine benachbart sind. 1492 ist nicht zulässig, weil 1 und 2 benachbart sind. Eine DEFCAB-Linie mit 5 Zahlen kann daher nur die Zahlen 1,3,5,7 und 9 in irgendeiner Reihenfolge enthalten.

Tricky idea!
Why not simply ANTI-Renban? :-)

Not the hardest puzzle, but excellent nonetheless. This has to go on my list of favourites!
*** Glad to hear that :-)
It's a fun constraint that could be interesting in future puzzles.

About DEFCAB lines :
- Is 4568 valid ?
- Is 5746 valid ?
I'll try it after work :)
*** No that is not valid. If you rearrange the digits along a DEFCAB line in ascending order the digits still have to be non consecutive.
