So ChinStrap kindly asked for a full quad-rank somedoku puzzle, and here it is.
- Somedoku: Fill each cell with a digit from 1-9 such that row N and column N contain exactly N unique digits.
-
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, ⋯)

That was wild! I love that this puzzle exists with this combination of eccentric rules. It's cleverly designed

Brilliant puzzle! I really liked how you set traps, so some digits turned out to be a surprise. Thanks

Loved it! It was really fun and different using the ranks to untangle the placements and eliminate possibilities.

After a brisk start, I decided that it would be an easy, but I had to spend two hours, perhaps I should have written down all the rank numbers on a piece of paper) Thank you
I must also say that together with Somedoku, quadfullrank doesn't look as intimidating as usual.
