Sudoku Books
Due to the popularity of Sudoku, publishers have started printing sudou books since last year. The books contain a big number of sudoku puzzle (the normal book has an average of 100 sudokus). Some books contain puzzles of only one difficulty level and others come divided in three subsections (Beginner, Intermediate and Advanced levels). We recommend books that have enough space in the grid for the "mark-ups". Also, books with puzzles various difficulty levels are better since you can quite easily get bored by playing the same type of puzzle frequently.
