Have a Sudoku solved — with a reason, not just a number

SudoSolver takes any puzzle: typed in, copied from a newspaper, or scanned by QR code from your own printed sheet. And then it does not simply show the answer — it shows the next logical step.

Two ways in

Free entry: type the puzzle in — from a newspaper page, a booklet, wherever. SudoSuite QR: scan the code next to the puzzle on a sheet you printed yourself. No retyping, no transcription mistakes.

The QR code holds the givens of the puzzle — nothing else. Nothing is uploaded and nothing is stored.

SudoSolver: choosing between free entry and QR scan

Step by step — and you learn on the way

Step 1

The next move

The solver shows exactly one step — not the whole grid. You remain the one solving the puzzle.

Step 2

The reason

Along with the technique behind it: Locked Pointing, X-Wing, XY-Chain. Marked in the grid so you can see what matters.

Step 3

The lesson

Technique unknown? One route leads straight into the lesson in SudoLearn — learn it, practise it, come back, solve it yourself.

That is the difference: apps that solve Sudoku are everywhere. One that makes you better at it is not.

And where does the sheet come from?

From the same app — or as a ready-made PDF from this site.
