Poikilos Sudoku
(Published on 3. January 2021, 06:00 by ICHTUES)
Rules:
- Normal Sudoku rules apply.
- Digits along marked diagonals cannot repeat.
- The sum of the digits on the orange ring equals to the sum of the digits on the yellow ring.
- Cells separated by a queen's move in chess cannot both contain 9s.
- The 5th (middle) box is a magic-box: Each row, column and diagonal in box 5 has an equal sum.
- Digits separated by a black dot are in a 1:2 ratio. Not all dots are necessarily given.
- Digits on a thermometer strictly increase as they move away from the bulb. However, the bulb of the thermo in column 8 is missing on one of its endpoints, whose location should be deduced by the solver.

Very great problem. I beileve that 16 corners are 6789 and 3*1234, but it's a bit hard to prove that( used about 10min )

Awesome puzzle! Got a little stick until I remembered the queen constraint. Beautiful logical path through the whole puzzle thanks.
