Gray Insert "Solution for a square":

You can have four possible answers:
• One solution for a square and the grid in progress is correct.
• One solution for a square but the grid in progress is wrong.
• No solution possible and the grid in progress is wrong.
• Input Error with equal numbers in row, colomn or area.

Rules:

Our irregular Sudoku puzzles are 9 X 9 sudoku. Instead of having nine 3 X 3 square areas, these 9 areas are irregular shapes. The rules are the same as for a classic sudoku. You need to find by deduction nine different digits by row, column and area.

Browser:

We recommend Google Chrome which is easy to use and displays with impressive speed advice and various solutions sent by the server.

Directions:

This page allows you to enter the solution of an irregular sudoku grid.

Entering a number with the mouse:
• Select your square by clicking in it.
• Click on one of the numbers in the left column.

Entering a number with the keyboard:
• You can move the cursor with the four arrow keys and the Tab key on the keyboard.
• Type the number in the appropriate square.

The numbers in blue are those of the puzzle and cannot be changed.

Tips:

The button (Solution for the grid) Display the solution for the current grid.

The button (Check/resolvability) checks that numbers are not repeated and ensures the consistency of the puzzle without giving the solution.
