Sudoku is a logic-based puzzle game. Follow these simple steps to solve Sudoku puzzles easily. The goal is to fill every row, column, and 3x3 box with the numbers 1 through 9 without repeats. You do not need math skills to solve Sudoku, only patience and a willingness to look for patterns.
Look for rows, columns, or boxes with many numbers filled in. When you see a line that is only missing one or two numbers, it is often easy to place them. Scanning keeps your eyes moving and helps you spot simple placements quickly.
Check which numbers are missing and eliminate impossible options. For each empty cell, use the row, column, and box to narrow down the candidates. If a number already appears in the same row or column, it cannot go in that cell. Writing small notes for candidates can make eliminations easier to track.
Place numbers that can only fit in one position. These are often called singles. You might find a hidden single when a candidate appears only once in a row, column, or box. Filling singles opens up new spaces and makes the next round of scanning faster.
Sudoku is solved by repeating the scan, eliminate, and fill cycle. If you get stuck, look for simple patterns like pairs or triples, where two or three cells in a unit share the same candidates. This can remove those candidates from other cells and create new singles.
