How to Play

• Objective: Fill the 9×9 grid so each row, column, and 3×3 box contains digits 1-9 exactly once.
• Basic Rules: No number can repeat in the same row, column, or 3×3 subgrid. Each puzzle has only one correct solution.
• Getting Started: Look for cells where only one number can fit, or focus on rows/columns/boxes that are nearly complete.
• Strategy Tips: Use logic and elimination rather than guessing. Scan for patterns and eliminate impossible numbers.
• Game Controls: Select a number from the digit panel, then click an empty cell to place it. Click a filled cell to remove your entry.
• Help Features: Use the hint button (3 available) for guidance, reset to clear your entries, or view the complete solution if needed.
