Play and solve your grid by penciling in the candidates


Principle:

For this you have two modes:
 • Manual mode allows you complete freedom to pencil in your candidates. It is for you to enter and delete them at your convenience.
 • Automatic mode updates all the candidates in relation to the number you enter or delete from a square.
You can switch from one mode to another by clicking on the button manual/automatic.


Presentation:

 • Large squares, white background, a figure in blue, represent the entire puzzle. These squares cannot be changed.
