Easy Sudoku

What makes a Sudoku easy?

Easy puzzles start with more given numbers, so there's almost always a cell where only one digit can legally fit. You solve them by scanning — reading a row, column, or box and asking "which number is missing, and where can it only go?" No note-keeping required, no dead ends, no guessing.

If you're brand new, easy is the place to build the habit of looking before you place. Once you can finish these without pausing, medium — where you'll start keeping pencil notes — is the natural next step. New to the rules entirely? The how-to-play guide covers them in a minute.

Every puzzle here has exactly one solution and is always solvable by logic — if you're stuck on an easy board, there's a single number you've overlooked, not a guess you're missing.
