Inspiriation for this type comes from WSC 2017.
Solve online in F-Puzzles or CtC-app (thx Nick Smirnov!)
Place the digits from 1 to 9 in every row, column and 3x3-block. Apply classic sudoku rules. One digit acts as a wildcard. Cells with > symbol contain digits greater than the wildcard. Cells with < symbol contain digits smaller than the wildcard. It is part of solving to determine the value of the wildcard.
Solution code: Row 4, followed by column 9.

In other words, the less-than signs indicate that the digits that can go there range from 1 through W-1, and the allowed range for the greater-than signs is W+1 through 9, where W is the wildcard. Thank you!

The wildcard is one fixed digit for the whole puzzle. You have to find out, which one. Then some cells are marked with a relation sign that compares the digit in the cell with the fixed wildcard digit.

In programming, a wildcard is something with any value. So if it can have any value, it can be greater or smaller than itself. Is this not what it means for a digit to be a wildcard in this instance? Is it the case that each digit between 1 and 9 has its actual value with respect to the greater-than and less-than symbols, no matter whether or not it is the wildcard?

Well, the digit can't be smaller or bigger than itself, right?

What does it mean for a digit to be a wildcard? Can the wildcard go on a cell with a greater-than or less-than sign?
