Super Sudoku X 16x16 - Free Printable

- The puzzle is a 16x16 Sudoku variant where each row, column, and 4x4 box must contain the numbers 1 to 16 exactly once.
- Some cells are shaded gray; these are clues that must be used to deduce the remaining values.
- Start by scanning rows, columns, and boxes for cells with only one possible number based on existing entries.
- Use standard Sudoku logic: eliminate candidates from empty cells by checking which numbers are already present in the corresponding row, column, and 4x4 box.
- Progressively fill in cells with unique possibilities, then revisit areas to find new deductions.
- Continue this process until all cells are filled without violating the rules.
- The solution requires careful tracking of candidates and iterative elimination across the entire grid.
