## What is Sudoku?

The shape fits perfectly. But does the number belong there?
Welcome to Sudoku: Pieces, where the satisfying fit of a jigsaw puzzle meets the clever logic of Sudoku.
Your tray is filled with blocks carrying numbers. Your job is to find where they belong on a 9×9 board. Each piece fills several cells at once, connecting decisions across rows, columns, and boxes. A promising gap might be the wrong home. An awkward little piece might be the clue that makes everything click.
Follow the numbers. Read the shapes. Piece it all together.
TWO WAYS TO THINK. ONE SATISFYING SOLVE.
Every placement has to work in two ways: the block must fit the space, and its numbers must fit the Sudoku.
Complete the board so every row, column, and 3×3 box contains the digits 1 through 9 without repeats. The starting clues help you narrow down your options, while the shapes give you another way to see what belongs where.
You might spot a number that rules out a whole section. You might notice a gap that only one piece can fill. The fun is in bringing those discoveries together.
PICK UP A PIECE. FOLLOW AN IDEA.
Drag blocks onto the board, or tap a piece and then tap where you want to place it.
Need to rethink your arrangement? Return a placed block to the tray and try another approach. Work around the starting clues, explore possibilities, and watch scattered pieces become a complete Sudoku.
That moment when the last few pieces fall into place? You earned it.
FIVE DIFFICULTIES TO GROW INTO
Start with Easy for generous clues and smaller pieces. Move to Normal for a balance of number logic and spatial thinking. Hard gives you fewer clues and more to untangle, while Expert asks you to think further ahead.
Then there is Hell.
No starting clues. A completely blank board. All 81 cells waiting for you.
Just you, the pieces, and the rules.
YOUR SOLUTION COUNTS
Find an arrangement that fills the board and follows every Sudoku rule, and you win. Any valid solution is accepted, giving you room to discover your own way through the puzzle.
Whether you begin with the most distinctive shape, focus on a promising row, or build around a useful clue, the next breakthrough is yours to find.
LEAVE A PUZZLE. COME BACK WITH FRESH EYES.
Your progress is saved on your device, with a separate ongoing puzzle for each difficulty. Switch to an easier challenge for a change of pace, then return to the tougher board when you are ready.
Track your wins and best completion times for each difficulty. Enjoy the solve, or see whether your next attempt can beat your personal best.
For Sudoku fans who love a fresh way to reason, and jigsaw fans who want every piece to mean something, there is a whole board waiting to come together.
Pick your first piece.
