Sudoku

A quiet grid. Nine numbers. One clear solution. 9 × 9 · One validated base, reshuffled. Use the controls below, or return to the main game page for more games.

How to play

  1. Select an editable square, then a number from the pad or keyboard. Given numbers stay fixed.
  2. Each row, column and 3 × 3 box must contain 1–9 exactly once. Repeated numbers are highlighted.
  3. Undo or clear entries. Hint fills one answer cell. New puzzle transforms one uniquely solved starting pattern; it is not a curated difficulty ladder.
