I just buy a new book (writen in french)
I like the part I understand but some part of it seem to be very difficult
Can someone try to explain the part i can't understand
If someone is volunteer and let me know, I will described the difficult part of it
By the way, the understandable part is very very instructive But Dont try the ebook
The title of the book is
Cinq techniques pour terminer toute grille de sudoku
The author is Khoan VO KHAC
