This puzzle was created by Jakhob and wooferzfg.
In each of the 4x4 grids, place exactly 4 of the digits from 1 to 9, such that digits do not repeat in the 2x2 regions. Digits may not repeat in a row or column of the full 8x8 grid.
Each purple line contains a set of consecutive and non-repeating digits, in any order.
Digits on arrows must sum to the digit in the circle.
Neighboring digits on a green line must differ by at least 5.In cages, digits must sum to the number in the top left corner of the cage. Digits cannot repeat within a cage.
Solution code: Row 1 followed by Row 8

Such a fun puzzle! Took me a minute to understand the rules but really loved the logic once I did!

Wow, that was a super cool break-in and silky smooth follow up. Loved it

Loved the way the four by four grids influenced but didn't dominate each other.

Very entertaining puzzle ! The interaction between the 4x4 is very cleverly designed.

That was lots of fun, and it was really satisfying to see how each grid unfolds itself. Great job achieving this rating :)

Cool puzzle! The logic was tighter and a lot more elegant than I expected.

Astonishing puzzle, from the break-in to the finish. Thanks for setting and sharing this gem!
I might have missed an easier deduction, but there was at least one step in the middle which I found clearly harder than a 2.

Maybe my brain is on vacation too, but I found that harder than 2*. Very nice logic though. Thanks for the puzzle.

Totally agree - it was such a fun puzzle. It was a different way of thinking, but not too hard, nor too easy. I wish there were more puzzles that were easy but innovative and creative. Well done.

This was such a fun puzzle! The logic made me smile a lot! The 4x4s interacting with each other was very satisfying and I enjoyed coloring them all first as much as I could before focusing on digits!
