How to play Sudoku

  • • Tap a cell, then tap a number to place it — or use your keyboard (1–9, arrows, backspace).
  • • Fill every row, column, and 3×3 box with the digits 1–9, with no repeats.
  • • Bold cells are given clues and can't be changed. Red cells show a conflict in that row, column, or box.
  • • Use Notes mode to pencil in candidates for a cell before committing.
  • • Solve today's puzzle to grow your streak and earn XP.
