MANY OF PROBLEMS ARE TRICKS WITH SOMEWHAT DUBIOUS ANSWERS. LOVELY DESIGN AND PAPER THAT LOOKS ARCHAIC. I FEEL IT IS FOR A MIDDLE TEENAGER RATHER THAN AN OLD PUZZLE SOLVER, IT IS A NICE BOOK BUT A BIT SILLY.
A really nice book both in content and feel. It does not get 5 stars because I feel it misses a trick by not containing riddles that would really make this a great book. Challenge your kids (and adults) with this book. A good buy.
