What could be more appealing to Mensa members--or anyone who enjoys a good challenge--than a cunning test of intelligence and logic? That's exactly what these 250 puzzles provide. The trick to kakuro is in making it all add up: the game begins with a grid that looks like a crossword, except that some squares contain small numbers in the corner. Fill in all the empty boxes using the numbers 1 to 9 without repeats so that the sum of each horizontal set of digits equals the number in the black triangle to its left, and the sum of each vertical set of digits equals the number in the triangle above it. The kakuro puzzles start out simple...and get more difficult as the book progresses.

The bestselling author of Zero shows how mathematical misinformation pervades-and shapes-our daily lives. According to MSNBC, having a child makes you stupid. You actually lose IQ points. Good Morning America has announced that natural blondes will be extinct within two hundred years. Pundits estimated that there were more than a million demonstrators at a tea party rally in Washington, D.C., even though roughly sixty thousand were there. Numbers have peculiar powers-they can disarm skeptics, befuddle journalists, and hoodwink the public into believing almost anything. "Proofiness," as Charles Seife explains in this eye-opening book, is the art of using pure mathematics for impure ends, and he reminds readers that bad mathematics has a dark side. It is used to bring down beloved government officials and to appoint undeserving ones (both Democratic and Republican), to convict the innocent and acquit the guilty, to ruin our economy, and to fix the outcomes of future elections. This penetrating look at the intersection of math and society will appeal to readers of Freakonomics and the books of Malcolm Gladwell.

Kakuro are language-free number puzzles that use pure logic and require just simple arithmetic to solve. This book contains 150 kakuros. It takes cue from the belt colors in martial arts: white is for novices, green for intermediates, brown for very accomplished players, and black for those consummate experts who crave a challenge.
