Answers to Questions (FAQ)

How to solve a 7x7 Sudoku grid?

A 7x7 sudoku is similar to a 9x9 classic sudoku, the difference is in the blocks that are irregular (jigsaw puzzle like) and whose shape depends on the played grids (the so-called blocks of size 7 form some sort of puzzle in the grid).

The sudoku7x7 resolution uses the same deduction steps as classical sudoku, but is limited to 7 digits (or 7 distinct characters).

On dCode, the resolution is done by indicating the contents of the boxes (only letters or numbers). NB: possibility to copy and paste 49 characters with a space as empty box.

To indicate the blocks of 7 boxes, click under the grid on one of the predefined examples or fill them manually by pointing the contours.

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

1
2
5
34
6
7

How does the step by step works?

The program resolves the 7x7 sudoku by simulating the deduction steps of a player and displays each of the steps in the resolution with an explanation.
