- Normal sudoku rules apply.
-
Full Quad-Rank:
- All the 2x2 areas of the grid, when read in western reading order, make a total of 64 four-digit numbers.
- Clues in the center of a 2x2 area show its rank among those 64 numbers, where the lowest is 1 and the highest is 64.
- One or more equal numbers are considered to be at rank N when there are N-1 numbers of strictly lower rank. (For example, we say there are three numbers in rank 20 when there are 19 numbers of lower rank and the next rank will be 23, i.e. the ranks could go ⋯, 19, 20, 20, 20, 23, ⋯)

I think 3* difficulty. After understanding the implications of the rules and the given ranks, the puzzle fell apart very quickly.

03:38:50 for me - I must admit - I didn't fully understand the implied rules of the quad rank and used LLM to help me along the way. i.e. do most of the puzzle :(
