Easy sudoku adds a single idea to the Beginner level: the Hidden Single. The puzzles stay approachable, but looking at one cell at a time is no longer enough.
Who this level is for
Easy is the second level. It suits players who are comfortable with the Naked Single and want a little more thinking. No complex elimination is required: you mainly need to look at the grid from two angles, the cell first, then the zone.
If you are coming from Beginner, the rule does not change. What changes is how you search. Some cells have no obvious digit, and you have to find the one that belongs there by scanning the row, the column or the box.
The techniques you need
Two techniques are enough. The Naked Single: a cell has only one digit left. The Hidden Single: in a row, a column or a box, a digit has only one cell left where it can go, even if that cell still accepts other digits.
To spot a Hidden Single, pick a digit and scan the boxes one by one. Look for a box where only one cell stays open for that digit once the rows and columns that already contain it are ruled out. The how-to-solve page walks through this move.
How to play here
This page gives you today’s Easy puzzle, renewed every day at midnight UTC. The board menu lets you load another puzzle of the same level. Hints and a check are available during the game.
The daily challenge, reachable from the leaderboard, is a single timed attempt: your time counts for the daily ranking, which requires an account. You can also print Easy puzzles as PDFs.
Moving up to Medium
Medium asks for the same techniques as Easy. The difference is that you have to chain them for longer, because progress comes by accumulation, not in big jumps.
When Hidden Singles come to you without effort, try a Medium puzzle. Your daily challenge time is a useful marker: if it keeps dropping from one day to the next, you are ready.

Frequently asked questions
What is the difference between Easy and Beginner sudoku?
Easy adds the Hidden Single to the Naked Single. You no longer look only for a cell that accepts one digit, but also for a digit that has one possible cell in a zone.
How long does an Easy puzzle take?
It depends on the player and on practice. The daily challenge timer gives you your own benchmark to compare from one day to the next.
How do I spot a Hidden Single?
Pick a digit and look at each box: if only one cell is left where that digit can go, it is a Hidden Single. Repeat the same scan on rows and columns.
When should I move up to Medium?
When you finish Easy puzzles without stalling and your daily challenge time becomes steady. Medium uses the same techniques, chained for longer.
