This part of the archive contains sudoku puzzles set by FullDeck and Missing a Few Cards (we're still in the process of uploading puzzles since the new website launched!). Puzzles set by our students are on the Ducklings archive page. Newer puzzles appear closer to the top of the page (but the fact that we're still loading puzzles from all of 2023 means there may be ones you haven't see further down the list even if you're a regular visitor). Use the search bar to locate puzzles by name or to find all puzzles with a particular constraint or at a particular difficulty level.
