Understand the Sudoku Grid
A standard Sudoku puzzle has a 9x9 grid, divided into nine 3x3 subgrids. Your goal is to fill each row,
column, and 3x3 box with the numbers 1 through 9 without repeating any number.
Start with the Clues - Sudoku Puzzles
Some numbers are pre-filled (called clues). Use these to begin solving the puzzle. Look for rows,
columns, or boxes that are almost filled, and try to figure out the missing numbers.
Scan Rows and Columns
For each empty square, check its row and column to see which numbers are already used. Eliminate
possibilities until you find the correct number for that spot.
Work Box by Box
Focus on one 3x3 subgrid at a time. Use the process of elimination to figure out where each number 1-9
should go in that box, based on what's already present in the rows and columns connected to it.
Double-check and Finish
After filling in all the squares, double-check that every row, column, and box has the numbers 1 through
9 without any repetition.
