Six Hit Wonder
(Published on 12. November 2025, 23:41 by marty_sears)
Rules:
Normal sudoku rules apply.
FOG: Entering correct digits may clear fog somewhere in the grid. No guessing is necessary.
HIT CIRCLES: All circles are outside the grid, and each must be filled with a digit. This digit indicates how many digits in its row or column match their distance from the circle. Eg: if a row with a circle at its left-hand end reads 123459786, then all of the digits except 6 and 9 match their distance from the circle, so the circle would contain a 7.
COUNTING CIRCLES: A digit in a circle also indicates how many times that digit appears in a circle.
GERMAN WHISPER LINES: Adjacent digits on a green line have a difference of at least 5.
ENTROPIC LINES: Any 3 adjacent digits along a hollow peach line must contain one digit from {1, 2, 3}, one digit from {4, 5, 6} and one digit from {7, 8, 9}.
EQUAL SPLIT LINES: Small white dots divide stripy blue lines into at least 2 segments, with the digits on each segment having the same total.
KROPKI DOTS: If a black dot sits between two digits, then one is double the other.
Solution code: Row 9 from left to right

Whew! Finished in only 648:42 (according to SudukuPad) over three days! Every “breakthough” I thought I had only got me a little bit ahead before I got stuck again.
I'd give this 7 out of 5 for difficulty, if I could.
Very nice, though!

Gorgeous puzzle, beautiful solve path. The break-in seemed impossible for the 30 minutes I kept staring at it, then that very first bit of logic hit me.

Great puzzle! I enjoyed that a lot, thank you

Incredible work, both of you! Took me just over an hour. I figured out the initial idea, then got very stuck after that... but pushed through and found the puzzle unravelled quite beautifully. The ending in particular was quite clever!
Excellent use of the border colours. They were helpful indeed.

WOW, that was probably the hardest puzzle I've done so far without needing help, but such beautiful insights along the way! The comment from @bboom was a big help. I didn't think colouring would be helpful in this puzzle but it was a great way to visually see how values interplayed across each other and the puzzle.

Incredible! Gotta use the side colors (or at least as a hint, I found it very helpful)

Super fun break-in. Took me a while to make some progress, but very satisfying when I did.

I found this to be a pretty big challenge but well worth it. I felt my brain growing as I solved it!

Another fun concept, I appreciate the border colors, about 15 minutes in I suddenly figured out how I should use them to my advantage. Took me just under an hour while multitasking, so the logic clicked pretty well for me.

Putting the last four digits after two and a half hours of work made me smile - what a wonderful finish! Thank you so much for creating and sharing this beautiful puzzle - both of you.
