This puzzle was made in collaboration with Calvinball, who came to me with the crazy idea for ranks determined by YY. I had an amazing time setting with Calvinball and we hope to make more in the future!

Thanks to lmdemasi and ChinStrap, and NEWS for testing!

Rules:

• Normal sudoku rules apply.

• Yin-Yang:
  • Shade cells using two colors such that each color forms an orthogonally connected region, and no 2x2 area is a single color. The warm pink line is a given shading border.

• Diamond Cave Clues:
  • Digits in cells with diamonds indicate how many cells of the same color are seen orthogonally, including itself. The other color blocks vision.

• Full Rank:
  • All the rows and columns of the grid when read separately for each color of yin yang shading make a total of up to 72 numbers of 1 to 9 digits.
  • All values are ranked in order from smallest to largest.
  • Clues outside the grid give the rank of one number in the row or column in the seen direction, which rank the clue references is to be determined by the solver.
  • For example, if a row contains ABcDefgHi, where lowercase letters are one yin yang shading and uppercase letter are the other, then from the left that row would produce ranks with value ABDH and cefgi and from the right that row would produce ranks with value HDBA and igfec.
  • For tied ranks, a number is at rank N when N-1 numbers are of strictly lower rank (e.g. If there are three numbers with rank 20, then there are 19 numbers of lower rank and the next rank will be 23, i.e. ⋯, 19, 20, 20, 20, 23, ⋯)
