This is the horizontal/vertical sudoku.


  • Every row and every column shall contain all digits 1 to 9 (no duplicates).
  • That's it. The 9 smaller squares of the standard sudoku do not apply.

The solver will always find a solution if it exists. If you press 'Solve', the solver will indicate that there is no solution, one solution, or more than one solution.
