How to use this Sudoku solver:

Select a digit on the right side bar of the grid first. Then tap the cell where you want to place the selected digit (or to remove the digit if the selected digit is in the cell).

After entering your Sudoku puzzle in this blank grid, press "Solve". Our online Sudoku solver will first validate your puzzle and then provide the answer if your puzzle is valid (which means that it has only one solution).
