How about a cereal called Puzzles & Games? The back of the box has a flap that pulls down into a game board. Edible bits inside would be game pieces (like chess or checkers, letters or numbers). Maybe the pieces vary for different editions. Or maybe the box come with a Magic Pen for solving invisible ink puzzles on the back. Fun and games that while helping sell cereal could help develop kids’ minds. And grownups’ too. (Hint to any cereal maker: I just happen to have invented a half-dozen original puzzles worth adding to the mix.)
