The World's Biggest Book of Brainteasers & Logic Puzzles

What a bargain! At more than 700 puzzle-packed pages, this huge, value-priced collection should keep any solver happy...and busy for a very long time.

It contains brain-busting challenges of almost every type: math logic problems for the numerically inclined; absolutely amazing lateral thinking conundrums; really great critical thinking bafflers; and mind-boggling word puzzles. Here's just a small sample of what's inside: The 22nd and 24th presidents of the United States had the same mother and the same father, but were not brothers.

How could this be so? Stumped? That's because it's one man Grover Cleveland who was reelected after skipping a term. And that's just an easy warm-up!
