Since enthusiasm for crossword puzzles starts young, I've put this in the 9-12 age classification, but would like to qualify that to say that there are not many puzzles which the nine and ten year olds could do; there are a good many among the easy puzzles, for the eleven and twelve year olds; and that the medium, hard and tricky (they are classified) are definitely geared to teen age. So put among your game books, suggest for a convalescent youngster -- and mention as a good ""family book"".
