Find out what it takes to become a puzzle
master. More than 500 IQ brainteasers–some of the most devious ever
published–offer a challenge that will stretch anyones analytic and
lateral thinking abilities to the limit. The requirements for cracking
these puzzles include a sharp mind, keen mathematical skill, and a
supremely logical approach. Go through a group of grids, determine the
logic in their organization, and decipher the missing pattern in the
final one. Check out the time on four different watches, and then
figure out what hour the fifth watch should read. Look at dominoes
lined up side by side, and calculate what number should appear on the
last domino to complete the series. Every puzzle is brainy fun.
