Finally, a way to play tic-tac-toe when a partner's not available. It's such a simple concept that you'll wonder why no one ever thought of it before. Here's how it works: each space in the grid has a page number and an X or an O. Fill one in, then turn to the corresponding page and find out what move the book wants to make. Keep on going until the game is done. There's just one way to come out a winner in each game--but it's not easy! Great for travelers, those waiting in line, or a child sick at home.
