Puzzle #80 in the Daily Sudoku League wasn't the original plan — a typo discovered during testing of a Mathrax Sudoku puzzle meant this Jigsaw XV Sudoku stepped in instead. The setter aimed to build a grid with no given digits at all, but found that made the puzzle too tough, eventually settling on just two symmetric hints to keep things fair while preserving an interesting solving path.
This puzzle is part of a run of new Sudoku variants featured in the Daily Sudoku League, many inspired by types appearing in the Sudoku Grand Prix Championship. Fans of irregular Sudoku and Sudoku variants will enjoy how the jigsaw regions interact with X and V clues here. Once solved, check out more entries in the Daily Sudoku League and explore other Sudoku variants across Fun With Puzzles.
Rules of the Jigsaw XV Sudoku
Jigsaw Sudoku Rules apply. Additionally, if an X is given between two adjacent cells, the digits in those cells sum to 10. If a V is given between two adjacent cells, the digits in those cells sum to 5. If an X or V is not given, the two digits cannot sum to 5 or 10.
