on elliptic hyperboles

- Irregular 10-sudoku rules apply: place the digits 0 to 9 once each in every row, column and region.
- The grid is toroidal: each edge of the grid is considered to be adjacent/orthogonal to its opposite edge. (Lines, regions and chess knight moves wrap around opposite sides of the grid.)
- Cells one chess knight's move apart may not contain the same digit.
- Digits along the grey thermometer increase starting from its bulb end.
- Beige lines are palindromes: their digits read the same in either direction.

While I agree that is was quite easy to forget about it being toroidal and thus maybe missing something somewhere, the break in was the easiest imaginable and within ten minutes three of the digits have almost fully (one x wing missing) been placed (so we're 35-40 digits in within 10 minutes) and the rest was straight forward filling in.. yes, irregular boxes and wrapping made that part require more concentration, but it's not "hard" IMHO.. so overall that was an easy puzzle, a very beautiful one at that and with a very nice idea.. I like it a lot.
Just hard it is not IYAM.

I released it with a suggested 3/5 difficulty, but i see why it consolidated to a 4/5. Maybe eventually it could be voted back down to 3/5...

OMG this puzzle was sooo awesome! Kept me engaged for days! (Probably not such a good thing since I have my exams coming up, but this was the only thing on my mind literally all day). I feel like I am cloud 9 after solving this puzzle!
It took me a long time but it was so worth it. A beautiful coloring exercise!
I really adore the idea - toroidal sudoku! Would love to see such more topology inspired sudokus in the future! You are a creative genius for composing this puzzle! Hats off!

So glad you liked it!!
There's 000K2A, it just came out. It's special for the hardcore topology fans :D

My biggest mistake was trying to enter the solution code using the second column from the right- that's column 9 in a 10-digit sudoku!

Brutal! 200 minutes to solve, but the discoveries along the way were very satisfying
