This is a spiral book. I don't see where it says book 3 on it.
Sudoku is the new puzzle craze. I love Sudoku. It is not a math puzzle, as it first appears. It is fun and easy and wonderful exercise to stretch the grey matter. Fill in the grid so that every row, every column, and every 3 x 3 box contains the digits 1 - 9. (Deluxe spiral bound edition--Book 3).
