Puzzle Books

Have fun while you expand your powers of deductive reasoning! Every one of these puzzles calls for conclusions based only on the information provided; the answers don't depend on previous knowledge, memory, wordplay, or deception - just a logical mind. Accept the alternatives that lead to the correct response and discard all faulty assumptions until you've arrived at the only possibility that makes sense. There are eight kinds of puzzles and many come with helpful diagrams.
