This jumbo book is jam-packed with the very best puzzles from our popular series, including dot-to-dot, mazes, picture puzzles, and spot the difference puzzles. There are time challenges with each one, so kids can try to beat the rest of the best. The only question is . . . are they up to the test? Encourage them to say yes, and tell them to get ready for hours of stimulating fun! Watch the intensity build as puzzles start easy but get harder along the way. Puzzles will challenge kids (answers are in the back) and get them racing to solve each one. Color them in, too!
