Once a Copycat, Always a Copycat
(Eingestellt am 9. Mai 2026, 11:52 Uhr von marty_sears)
Rules:
Normal sudoku rules apply.
COPYCAT CELLS: Nine copycat cells exist in the grid. They all contain the same digit (to be deduced), but they all have a different value. You can use the circles at the bottom to keep track.
The value of a copycat cell equals the digit in the cell that is 180° rotationally opposite itself. Eg: If r1c3 is a copycat cell, then its value equals the digit in r9c7.
MULTIPLE LINES: For two adjacent values along a grey line, one can always be divided by the other to give an exact integer - ie; one is a multiple of the other.
BLACK DOTS: If a black dot sits between two cells, the value of one is double the value of the other.
YELLOW DOTS: If a yellow dot sits between two cells, their values are NOT consecutive.
Lösungscode: Row 9 from left to right

I've been staring at this one repeatedly for the past week, but it wasn't until I listened to Simon reading the rules that something clicked and I realized the special property of this strain of copycat cells!
{Glad to see that it took Simon a while too, although his 30 minutes is still a lot faster than my week...)
From this point, I made slow but steady progress and finished the puzzle in about an hour.
Very nice!
Oh, and very belated birthday wishes to Scojo!

I found this one very hard. I'm not sure if there's something interesting I missed, but I kept finding that I'd make progress, then realise I had made unfounded assumptions (that all happened to be correct) and had to backtrack to prove why my assumption had been correct.
Marty: yes sounds like you might not have found the correct deductions. Everything should flow smoothly

Really love how you had to use every single possible angle of this ruleset at one time or another! And the whole time I was thinking "What's this useless nabner dot for?" Should have seen that coming!

It took me ages before figuring out what the break-in was, but once I did, everything flowed beautifully !

Amazing puzzle, thanks! So many satisfying deductions. Especially enjoyed both the break-in and the ending

Thank you for this lovely gift Marty! The twist of having all of one digit be copycats and a forced disjoint on values was a really fun play on the "standard" modifier meta

I needed a loooong time to understand the consequences of these special copycats. But then I got into a heartwarming flow. What a wonderful idea! Thank you very much for creating and sharing another Wow!-puzzle.

Your gut says Copycat puzzles are intimidating but it also says Marty Sears puzzles are super friendly and approachable. Trust the latter.

This was a tough one. Took a bit to wrap my head around the implications of the rules, but once the dominoes started falling it was a supremely elegant and satisfying solve. Excellent puzzle!

Fabulous! Weird ruleset, hard to fully grasp at first, but after that a phenomenal solve path. Enjoyed that a lot, thanks
