Sheep and Wolf Sudoku
(Eingestellt am 25. Juni 2024, 19:19 Uhr von mathpesto)
Rules:
Normal sudoku rules apply.
Diagonally adjacent cells joined by a black dot contain digits in a 1:2 ratio.
A circle contains a low digit (1, 2, 3) and a square contains a high digit (7, 8, 9). All low digits in the grid represent sheep and all high digits represent wolves. Middle digits (4, 5, 6) are neither animal.
Draw lines on the edges of some cells to create cages. Each cage contains at least one sheep or wolf, but a cage cannot contain both types of animals.
Lines cannot turn, except where marked with a black dot (they can also go straight through a black dot, however). Lines may intersect one another, but must travel straight at their intersection. Dots cannot be connected to more than one line, but dots are allowed to remain unused. Both ends of a line must reach the edge of the grid.
For those unfamiliar with sheep and wolf puzzles, here is a link to an explanation/example on puzzlink.

Thought it was pretty challenging but maybe it's just because it's my first time doing a puzzle like this

Really enjoyed it! I'd never done a sheep and wolf puzzle before, so it took me a bit to get used to the rules. Loved the break-in

I've not seen the 1:2 ratio dots in corners before. Do they imply that both of the diagonals made by the surrounding squares exist in 1:2 ratios, or that only one of the two diagonals forms a 1:2 ratio, and the solver is left to deduce which one it is?

Both diagonals have pairs of cells in a 1:2 ratio.

I like this new hybrid very much. Needed some fresh logic while solving the puzzle. The construction is perfect. Thank you so much for sharing.

I really love this puzzle but I think the rules are not quite complete (as written, I think you could claim that one could simply draw some lines that create one cage and leave the rest uncaged). I think perhaps the simplest modification (and what I assumed while solving) is that each edge of the grid is considered drawn for the purposes of cages, which I believe is equivalent to requiring all cells to be in cages.

Took me a little while to grasp the Sheep and Wolf rules, but once I did it was smooth sailing! Some funky and fun logic in this!
