Killer Sudoku: The Fearsome Twelves

(Eingestellt am 1. Dezember 2022, 19:43 Uhr von Playmaker6174)

Giving myself another go on setting a pure killer sudoku, and this time it has a theme into it. I set this puzzle based on a nifty (and intricate) idea that I constructed for the beginning, and it's probably one of my favorite ones that I've set in a while.

The puzzle might be quite challenging but it's also very engaging from my point of view and it should be worth your efforts as the solve goes on. I'll also leave some hints if you're stuck at the beginning (but I encourage you to actually try to figure out the hidden idea by yourself!).

You can also leave a comment on which cage total I should try next (either a single total or a combination of only two distinct totals). I hope you enjoy!


- Normal Sudoku rules apply: every row, column and 3x3 box contains digits from 1 to 9 each once.

- Digits within a cage don't repeat and they must sum to the small number written in the top left of that cage. In this case, the total of every cage is 12.

Good luck and have fun solving!

Hint (highlight to view):

- Look around row 123 and think about the distribution of some low digits (mainly 1s and 2s).
- Look deeper at the 3 cells 12 cage in box 1 and think about some certain digits that it needs to contain using its interactions with other cages. This will force some cages around it.

Lösungscode: Row 8 (left to right) and column 9 (top to bottom), 18 digits long with no space
