Kropki Sudoku is one of the most popular Sudoku variations and is widely featured in the World Sudoku Championship and other international Sudoku competitions. Along with the classic Sudoku rules, a white dot between two orthogonally adjacent cells indicates that the digits are consecutive, while a black dot indicates that one digit is exactly double the other. The pair 1 and 2 is special because it satisfies both conditions and may be connected by either a white or a black dot. These simple rules create many elegant logical deductions throughout the puzzle.
Although the rules are easy to understand, Kropki Sudoku offers a rich and rewarding solving experience. Every dot provides valuable information, allowing solvers to eliminate candidates and uncover the correct solution using pure logic. If you enjoy Sudoku variants that combine simple rules with deep logical reasoning, this handcrafted puzzle is sure to keep you engaged until the final cell.
