### How to solve a 8x8 Sudoku grid?

An 8x8 sudoku is a sudoku of 64 cells (eight rows and eight columns) that can be solved like a classic 9x9 sudoku except for its irregular blocks, whose format depends on the grids played.

The 8x8 sudokus resolution follows the same reflection steps as classical sudokus, but with only 8 digits (or 8 distinct characters).

On dCode, indicate the contents of the boxes (with only digits or letters).

Example: The content `8 6 3 5 4 2 7 1` can be pasted in the first box to get

 8 ␣ ␣ ␣ ␣ ␣ ␣ ␣ ␣ ␣ ␣ ␣ ␣ ␣ 6 ␣ ␣ ␣ ␣ 3 ␣ ␣ ␣ ␣ ␣ ␣ 5 ␣ ␣ ␣ ␣ ␣ ␣ ␣ ␣ ␣ ␣ 4 ␣ ␣ ␣ ␣ ␣ ␣ 2 ␣ ␣ ␣ ␣ 7 ␣ ␣ ␣ ␣ ␣ ␣ ␣ ␣ ␣ ␣ ␣ ␣ ␣ 1

### How to indicate 8x8 Sudoku blocks?

To indicate the blocks/groups of 8 cells, click under the grid on a predefined example or fill countours manually by pointing them.

### How does the step by step works?

The program resolves the 8x8 sudoku by simulating each of the deduction steps of the player and displays each resolution steps with their explanations.
