The book is a series of "mazes" - each page features a different piece which can move through the maze according to its chess move, avoiding various pitfalls. My 6 year old son loves this book - he picked up the idea easily, even though he as yet has no idea about actual chess. I enjoyed helping him with it (we ended up fighting over it) as there is enough detail so an adult has to concentrate too. My only moan about it is the lack of solutions, good in one way because my son is an inveterate cheater, but frustrating when I can't solve the puzzle either!
