- Identify the 16x16 grid divided into 4x4 subgrids.
- Use digits 0-9 and letters A-F (representing 10-15) to fill the grid.
- Ensure each row, column, and 4x4 subgrid contains all 16 unique values exactly once.
- Apply standard Sudoku logic: for each empty cell, determine possible values by eliminating those already present in its row, column, and subgrid.
- Start with cells having the fewest possible candidates to make logical deductions.
- Progressively fill cells using single candidate placements and cross-hatching techniques.
- Verify that no value repeats within any row, column, or 4x4 box after each placement.
- Continue until the entire grid is filled correctly according to Sudoku rules.
