The concept is marvelous, but the puzzles aren't real riddles (being neither funny nor traditional). Children would have the most fun coming up their own puzzles for the presented dollar words, or coming up with their own words. A dollar word is a word that has letters that add up to exactly 100, given that each letter has a value assigned to it so: a = 1, b = 2, c = 3,... y = 25, z = 26. 'Henrietta' and 'elephants' are examples. Play the game yourself - you don't need the book! ( )
