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: Put a digit from 1 to 9 in every empty cell. Clues in the top right triangle indicate the sum or product of all numbers to the right of the clue cell up to the next clue cell or the border. Clues in the lower left triangle do the same for the numbers in the column below.
In a sum (or a product), no digit can appear twice. (This also holds for line segments without a clue)
Solution code: Row 4 and column 9, ignore black cells (alltogether 18 digits)

@jchan18: The first row/column is counted as well, even if there are no empty cells (so you're looking at row 5 and column 10)
