Killer Octopus

Both of these have been good fun to explore and to set and I recommend trying both. I reckon this "Octopus" ruleset has a lot of legs...
Normal sudoku rules apply.
Digits in a cage must sum to the given total.
Octopus rules apply. I.e. draw 4 lines that must:
- not cross or overlap anywhere except r5c5, where they all intersect;
- have 180-degree rotational symmetry around r5c5;
- visit exactly 2 cells on the edge of the grid, which are the beginning and end of the line;
- all be the same length (in no. of cells passed through).
The 4 lines are "Same Difference" lines. I.e pairs of adjacent digits on a line must all have the same difference, though this difference may be different for different lines.
Lösungscode: Top row, left to right

We want more octopi! Very fun puzzle, a little tricky with the break in and then the rest unfolded pretty smoothly.

This was amaaazing. I think I even preferred this a little bit more than the other octopus puzzle, as this ruleset felt a bit cleaner and simpler and thus a bit more elegant. The placement of the 5 cage is sheer genius and the work it does is remarkable. Still can't believe only 4 small cages are needed to make this grid have a unique solution. It's a miracle I tells ya

That was amazing! It felt like so little information given in the clues, yet it unfolded beautifully. Very original feeling logic too. Thank you!

a much easier version with surprisingly different logic. Very elegant.
