Twelve Spots
(Published on 31. August 2024, 03:06 by marty_sears)
Rules:
- Normal 6x6 sudoku rules apply.
- Draw 6 lines, each with a different turquoise spot at both ends. Each line must occupy at least 3 cells, and may move orthogonally and diagonally. Lines may not branch, cross each other, or share cells.
- Each line is a 'same difference' line. Every pair of adjacent cells along a line has the same difference - this is its 'difference value.'
- Every line has a different 'difference value'.
- Digits in a cage sum to the total in the corner.
Please leave a comment if you enjoy :)
Solution code: Digits on lines in row 4, from left to right

Good puzzle. It's easy and difficult at the same time in a pleasing way.

Was wondering about the difficulty rating for this and then I remembered that doing Sudoku is a thing!
Lovely as always, thanks Marty

Hi, new here.
Would someone help me understand the rules a bit?
Does the turquoise balls count as a cell in a line or is it so that there need to be at least 3 cells between the turquoise balls?
Marty: Welcome! Yes the turquoise spots count as cells on the line
Fro: Thanks! :)

A beautiful unfolding of surprising secrets. I felt so smart and so stupid at the same time. Loved it

I looked at this briefly and couldn't understand the low difficulty. Figured out the way the rules worked and it was so clever.
Favorite puzzle in a long time, and so approachable!

One of the nicest 1* puzzles! Would be great to see a 9x9 version.

Good one! I hope someone does a video on this one, i've kinda gone with my intuition on the last 3 lines, i felt like it was the only way, but i didn't bother to prove to myself that it definitely was the only way.

Marty, I need you to stop being so clever, at least not all the time... I'm running out of synonyms for the word "genius".

Wow! Quintessential Marty in the best way. Seems impossible until you get in the right mindset.

Funny little puzzle with a smooth solving path - once you get your head around the ruleset. Thank you very much for sharing.
