Gray Insert "Check your irregular sudoku puzzle":

You have three acceptable results:
 • The current puzzle is correct and has only one solution.
 • The current grid is wrong and has no solution!
 • 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 (Possibilities for all squares) displays all the candidates for all the squares in the grid.

The button (Tip for a square) displays all the squares which accept a solution with the basic solving methods. This aid is very useful and sometimes disconcerting for beginners wanting to learn about this version of Sudoku.
