How to Play Sudoku

Sudoku is a logic-based number placement puzzle. The objective is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 sub-grids that compose the grid contain all of the digits from 1 to 9. The puzzle starts with some numbers already in place, and you must use logic to fill in the rest.

• Fill the grid: Place a number (1-9) in each empty cell.
• Rows: Each number from 1-9 must appear exactly once in each row.
• Columns: Each number from 1-9 must appear exactly once in each column.
• 3x3 Blocks: Each number from 1-9 must appear exactly once in each of the nine 3x3 blocks.

The game provides a "Check" button to see if your current numbers are correct and a "Solve" button if you get stuck!
