Pseudo Differences
(Published on 20. February 2024, 21:00 by marty_sears)
Rules:
- Normal sudoku rules apply.
- Every row, column and box contains exactly one 'pseudo cell'. The nine pseudo cells contain a complete set of the digits 1-9.
- The real value of a pseudo cell is calculated by adding its row number to its column number. Eg: if there is a pseudo cell in r5c6, it has the value of 11 (regardless of which digit appears in that cell.)
- The values of every pair of adjacent cells along a turquoise line have the same difference. In this puzzle, this 'same difference' is unique for each line. Ie: adjacent values on one line will never have the same difference as adjacent values on another line.

I could identify the differences of all the lines and solve about half of the grid entirely before I got stuck. Had to pick a cell and try both options to move on. Other than that, a very nice and difficult solve but entirely doable with just logic!

Like every great romance it seems intriguing but impenetrable at first but slowly and gradually reveals its secrets with perseverance. Thoroughly enjoyable.

Excellent puzzle! I found this much harder than Pseudo Science, and I was nearly pulling my hair out trying to find a way to resolve all the lines with different differences. Maybe it's just me? Even so, I really enjoyed discovering how it all came together.

It was really cool how the pseudo cells were used to create the unique differences!

It wasn't necessarily the flashiest in the series but it may very well be the most elegant setting in the entire series. Incredible, incredible puzzle.
