Two Cell Ratio Sudoku

(Published on 6. January 2021, 20:01 by SirWoezel)

Inspired by PrimeWeasel's Multiple Cell Kropki (ID 0004ZO), which deserves more solves, and the Two cell kropki (ID 000538) by bigger / Old Miles (ditto).

This puzzle has a nice, logical solving path and is quite a lot easier than the mentioned puzzles. Hopefully it will be a nice stepping stone to those two puzzles. I estimate this at 2.5 or 3 stars for difficulty max.

- Standard Sudoku rules apply.

- A black dot indicates that the first two cells on one side of the dot have a sum that is double the sum of the first two cells on the opposite side. All possible black dots have been given.

Highlight the next line for a mild hint!

When you look at -for instance- row 1, basically you can say it reads: A+2A + B+2B + C = 45. In other words 3A + 3B + C = 45. This really limits the options for C.

Have fun solving!

Solution code: Row 8 and Row 9

Interesting idea, and a clever start. I found this quite tricky though.

Wow! I may have created one of the few puzzles cdwg2000 didn't solve (wink wink hint hint)! Maybe 2.5 to 3 stars was a bit too optimistic.
