How to solve Easy Sudoku
What makes a puzzle Easy is the hardest step it needs. Most often that step is Nearly Complete (95%).
Look for a row, column or box with only one or two empty squares and fill in what is missing. When that runs out, pick an empty square and check which numbers its row, column and box already hold: if only one number is left, it goes there.

Do Easy puzzles need guessing?
