1. Grid Structure: The puzzle is played on a 9×9 grid, which is divided into 9 smaller 3×3 subgrids.
2. Filling the Grid: The goal is to fill the entire grid with digits (1-9).
3. No Repetition: The numbers 1 to 9 must appear exactly once in every row, every column, and every 3×3 subgrid.
4. Clues: Some cells of the grid are pre-filled with numbers, and the player must deduce the placement of the remaining numbers based on the rules.

• Every row contains the digits 1 to 9 (no repetition).
• Every column contains the digits 1 to 9 (no repetition).
