Comprimes in the Fog
(Eingestellt am 24. August 2023, 20:24 Uhr von gdc)
This puzzle uses a special "anti-coprime line". It is my first time combining a coloring puzzle with fog of war rules. Hope you enjoy!
- Normal sudoku rules apply
- Fog of war: The grid is partially covered in fog. Placing a correct digit reveals clues in the surrounding 3 by 3 area
- Digits on a line may not repeat. Adjacent digits on a line have a common prime factor. Lines never share a cell with another line.
- Digits joined by a white dot are consecutive

Rules Clarification
Two different digits from 1-9 have a common prime factor if and only if they are both even or both divisible by 3.
- 2, 4, 6 and 8 can connect with each other
- 3, 6 and 9 can connect with each other
- 1, 5 and 7 cannot connect with any other digits
- 5 and 7 could connect with themselves, except this would violate the rule about digits not repeating on the line.
The rule "lines never share a cell with another line" implies that multiple line-ends cannot meet at a cell.
Difficulty
This puzzle should sit somewhere between 2 and 3 stars and has a relatively straightforward break-in/eraly-solve that showcases the most important ideas of the line type.
Lösungscode: Row 7 (9 digits)

Interesting new rule for me, once I wrapped my head around it and starting sprinkling a little colouring around, it slotted beautifully into place.

Beautiful beautiful puzzle! Not too difficult once I understood the rules... Still took me a while to solve. But what an enjoyable solve it was! Thank you

the coprime rule is an interesting way to partition the digits, but feels a little restricting in terms of scope for future puzzles. works nicely in this one though!

Fun puzzle when I got the hang of the rules.

Well, I thought I had perfection and then I eliminated a digit from my pencil marks that was actually the RIGHT digit, so I have one accidental "cheat" on the fog part, but otherwise it was fun.

Took me a bit to get my head around the rule, but once I had, it came along pretty nicely. Right cool puzzle!

Very nice fog of war, it was approachable but interesting to work through the lines. I didn't use any coloring or lettering.
