  • Normal sudoku rules apply.
  • Cells one long jump apart may not contain the same digit. (A long jump, a.k.a camel move in fairy chess, is a move 3 cells in one direction and 1 cell in an orthogonal direction, for example cells r5c5 and r2c4.)
  • Also, diagonally adjacent cells may not contain the same digit.
  • Adjacent digits along a green line must have a difference of at least 5.
  • Digits joined by a black dot are in 1:2 ratio, and digits joined by a white dot are consecutive. Not all possible dots are given.

Hint: (highlight below)

The anti-king + anti-camel combo has a symmetry of order three that doesn't appear in the anti-king + anti-knight combo. In this instance, this symmetry makes the exact same three boxes repeat all over the grid.

Wow, that was awesome... I had to look at the hint though I'm afraid;
and after I saw what that means to the puzzle I thought it'd be smooth surfing especially after I got the fives in. it was shattering to see that there is still another incline to crawl up.
Hehe enjoyed it a lot! thanks a ton

Great puzzle! Thank you

The symmetry induced by the anti-camel-anti-knight interaction is truly magnificent. You've discovered a beautiful pattern. That said, this was very hard. The logic needed to start placing digits was far from immediate...however, quite beautiful once cracked.

That was hard. I couldnt easily find a way to disambiguate high/low so I had to use bifurcation in the end.

***

did you use the thing with the boxes?

After i bifurcated and solved i thought there was a logic but couldnt put my finger on it.

i'll expand on the hint
