Solving walkthrough
How to Solve Easy Sudoku — Step by Step
Pick the digit with the most givens (often 1, 5, or 9). Scan each 3×3 box. In every box where that digit is missing, identify the rows and columns within the box where the digit cannot go because it already exists elsewhere in those rows/columns. The single remaining cell is your placement. Repeat for the next-most-common digit.
Pro tips
Pro Tips for Easy Sudoku
- Scan row by row first. Easy Sudoku rewards systematic horizontal scanning before column or box scanning, because most given clues are placed to make row-scanning productive.
- Look for digits that appear most often in the givens (commonly 1, 5, or 9). The digit with the most givens is usually easiest to complete first.
- Avoid pencil notation on Easy puzzles. If you find yourself notating multiple candidates per cell on Easy difficulty, the puzzle has a single-candidate path you have missed — return to scanning.
- Time yourself. Most Easy Sudoku puzzles should complete in under 15 minutes. If you exceed 20 minutes regularly, try Medium puzzles — the resistance is what makes them interesting.
Common mistakes
