 How the game works 

An irregular sudoku is composed of nine nested zones of irregular shape.
The protocol of the game remains the same as a regular sudoku.

 A very fast browser 

The use of Google Chrome is highly appreciated for its speed of display. We advise you.

 Small Features 

The button (Possibilities for all squares) displays all the candidates for all the squares in the grid.

The (Tip for a square) button displays all the empty boxes that have a possible solution with a basic method. This feature is sometimes disconcerting by the number of possible boxes.
