Where to start
Look at row 2, column 3: only one number fits there.
The rules
Every row, every column and every 3×3 box must contain the numbers 1 to 9, each exactly once.
Tips for solving it
- Start with the numbers that appear most often in the grid: they have the fewest free spots.
- For each box ask yourself: where can the missing number go? Often there is only one place.
- If a cell already sees most numbers in its row, column and box, count the ones left.
- Write lightly in pencil: if you make a mistake, you can erase it cleanly.
