Hexadoku
Hexadoku is a popular Sudoku variant that expands the familiar puzzle into a much larger 16×16 grid. While traditional Sudoku uses the numbers 1 through 9, Hexadoku uses the hexadecimal numbering system, which includes the numbers 0-9 and the letters A-F. The goal remains the same, but the larger grid creates a very different solving experience.
The appeal of Hexadoku comes from its scale. With 256 cells instead of 81, each puzzle offers more opportunities for deduction, pattern recognition, and long-range planning. Solvers often find that Hexadoku encourages a different style of thinking than traditional Sudoku, making it a favorite among Sudoku enthusiasts looking for a new challenge.
