The aim of Sudoku is to fill in the grid so that every row, every column, and every box contains the digits one to nine. As each number is entered, mistakes will be shown in red. Your game will automatically be saved until you next return.

  • Reset: Set the puzzle back to the start.
  • Undo: Undo last step.
  • Hint: 1st time, a vague hint. 2nd - a clearer hint.
  • Step: Enter the next number automatically.
  • Clear: Clear the board / delete saved game.
  • Solve: Solve the puzzle (you cheat!)
  • Show: View picture - if Sudoku has been solved!
