Answers to Questions (FAQ)
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?
