Since 2021, we have posted some extra difficult Sunday Stumpers, about once a month. These will be quite tough puzzles, but with a logical path to be found (and solution videos to help). This eighth Sunday Stumper of 2022 is a Shape Sudoku by Salih Alan with a “Multiplication” theme in each of the shapes; while it might be a touch easier at 4.5 stars than some of our other stumpers, we expect you’ll still enjoy figuring out the intended solving path.
