Easy Sudoku

Around forty starting numbers and a solution you can reach by scanning alone. No pencil marks required.

What makes a puzzle easy here

An easy puzzle on SudokuPath is one the generator could solve using nothing but naked singles and hidden singles — the two moves you can make by looking at the grid, without writing anything down.

That is a stronger promise than a clue count. Every easy grid here has been solved by the same logic you will use, before it was published. If you get stuck, there is always a single you have not spotted yet.

How to work through one

  1. Pick the digit that appears most often in the grid and hunt for boxes where it has only one possible home.
  2. When a box has just one or two empty cells left, fill them — those are the cheapest points on the board.
  3. Work in rows and columns of three boxes at a time; a digit fixed in two boxes of a band usually gives away its cell in the third.
  4. Only reach for pencil marks when scanning genuinely stops paying — on an easy grid it should not have to.

A good place to start

If Sudoku is new to you, read how to play first — it is a five-minute read and it covers the only rule that matters. For children, the 4×4 grids use the same idea with four digits instead of nine.

Common questions

How many numbers does an easy Sudoku start with?

Between about 38 and 42 of the 81 cells. More than that and the puzzle solves itself; fewer and you start needing pencil marks.

How long should an easy puzzle take?

Most people finish one in four to eight minutes. Regular solvers are often under three.

Do I ever need to guess?

Never. Every puzzle on this site is checked for a single solution and for a complete chain of logical moves before it is shown.

Is easy Sudoku good for children?

The 9×9 easy grids suit about age eight upwards. Younger children usually do better on the 4×4 kids grids or the 6×6 mini grids.
