Product of Three
(Eingestellt am 18. Juli 2025, 08:40 Uhr von SumDumThum)
Rules:
Place the digits 1-9 once in every row and column.
3x3 boxes may contain only 3 distinct digits, each repeating 3 times.
A digit in a circle indicates the number of circles that contain that digit.
Links:
This puzzle was directly inspired by Pulsar's Spiraling Circles, which was in turn inspired by Atticus837's Hypnotic Suggestion.
If you rearrange the rows and columns of Spiraling Circles just right, you can move all the circles into a triangle on one side of a diagonal. The same is true of Hypnotic Suggestion, so long as you're willing to break the 8x8 sudoku boxes.
These permuted versions are related to the cyclic group C9. The inspiration for this puzzle was trying to get a similar effect using the other group of order 9, the product C3xC3.
Thus the title :)
Lösungscode: column 1

I'd recommend using sudokumaker to create puzzles. I love desmos - but not for puzzling. Here's a link to this project in sudoku maker:

It's easy to export a SudokuPad link from there, which is what most solvers are going to use to do the puzzle -- here's that link -- though I didn't put rules in yet:

No need to use the desmos.com link (couldn't work how to enter digits there), the first column fills itself pretty much instantly.
