In December 2021 there was a logic puzzle advent calender on mathebau.rocks, containing variants of standard puzzles. These puzzles are now uploaded to the puzzle portal.
Rules: Connect each angler (the numbers outside of the grid) by a line (fishing line, which goes only horizontally and vertically) with a fish, such that each fish is connected to an angler. The length of the fishing line is the sum of the numbers of the angler and of the corresponding fish. All cells have to have an fishing line in it and fishing lines cannot cross or overlap. A question mark stands for any number.
Solution code: Row 7 and column 4: L for an edge, I for a straight line, F for a fish.

@QuiltyAsCharged: I honestly do not know why you would want to solve this puzzle in Sudokupad and not use the existing link in Penpa-Edit. While Sudokupad is great for solving Sudokus (and maybe some other number-placement puzzles), Penpa-Edit is far superior regarding all other types of logic puzzles. Please give it a try first instead of manually copying the puzzle into Sudokupad!
