Currently Playing: How To Solve Phistomefel's Masterpiece

Here is a guest video by the brilliant Matt Bouyack - one of our incredibly intelligent and articulate viewers - in which he explains how to solve one of the best sudokus ever.... Just before Christmas, we were thrilled to share Phistomefel's first ever sudoku hunt with our patrons on Patreon. The final puzzle in the hunt, Ancient Wall, is considered by Phistomefel to be a sudoku he couldn't better in terms of its construction and the range of logical deductions necessary to solve it. It is a masterpiece. We have therefore decided to share it with our whole community to give everyone a chance to experience this extraordinary sudoku. If you'd like to try the rest of the hunt and experience the whole thing then do join us on Patreon (link below). It costs as little as $2/month. https://www.patreon.com/crackingthecryptic The links below include an example puzzle, which we recommend you try before attempting the actual full-sized version. Example: https://app.crackingthecryptic.com/sudoku/62HMGR8RNN Actual puzzle: https://app.crackingthecryptic.com/sudoku/bFgHtLg373 Rules Normal sudoku rules apply. Divide the grid into two sets of contiguous cells. Digits in a circled cell indicate the number of cells in the corresponding row and column combined that are in the other set. Not necessarily all circles are given. Many, many thanks to Phistomefel for creating the whole hunt. It was THE sudoku event of 2022!
