Product Arrow Sudoku is one of the most interesting arithmetic-based Sudoku variations to appear in the World Sudoku Championship. I created this puzzle as a practice exercise while preparing for the championship and challenged myself to design it without providing any given digits. Although achieving a perfectly symmetrical layout was difficult, the process helped me better understand the logical solving techniques used in this fascinating Sudoku variation.
Creating puzzles is often the best way to discover new solving ideas, and this puzzle taught me several elegant logical concepts. If you enjoy handcrafted Sudoku puzzles that encourage careful thinking and systematic deduction, this Product Arrow Sudoku is sure to provide a rewarding solving experience.
Rules of the Product Arrow Sudoku
Classic Sudoku Rules apply. Additionally, there are some arrows in the grid. The encircled 1, 2, or more digits form a number that must be equal to the product of the digits that appear along the path of the arrow. Digits can repeat within an arrow shape.
