Looking for a brain workout? Well look no further with a collection of Mensa-level conundrums. Puzzles range from classics like Battleships to "Hex Loops" - locate a path that travels through the adjacent hexagons: the trick is it has to end where it started, and the lines can't touch or cross.
An old favorite--Mensa Math & Logic Puzzles--gets a brand-new look: it's now in color! And the puzzles are fantastic: they're the kind of challenge found at the World Puzzle Championships, and they require no language to solve. For example, you are given a grid of dots that has some numbers (0, 1, 2, or 3) in them. You need to connect the dots in one continuous path so that each number is surrounded by that many lines. So a "3" means that three of the four sides around it must be connected. All the puzzles are similar abstract exercises, and all have unique solutions that can be reached using pure logic. They're difficult--and really satisfying exercise for your brain.
Logic, math, and fun come all wrapped up in one tricky puzzle package. Each little story gives you just enough information to determine what's bigger, who weighs more, how much gets sold, and lots of other confounding braintwisters. To make it just a little easier, every puzzle has a chart to help you organize and work out the all facts in your possession.
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!
Recreational mathematics at its best. Designed to give your brain some mental exercise; the puzzles range from entertainingly easy to devilishly difficult - there's something for everyone. 155 puzzles in 25 unique categories with help, hints & solutions. Math quotes, facts, humor & anagrams put the final touches to this interesting book.

You will find the following types of puzzles and logical problems: Lateral thinking: challenges that are seemingly impossible or require a lot of mathematical knowledge, but which really conceal a solution outside the box (in an indirect or creative way). Logical thinking: challenges that must be solved with logic, making inferences until finding the solution or, sometimes, eliminating the other alternatives. Mathematical knowledge: it will be necessary to know mathematical (and sometimes physical) principles to solve certain puzzles. Paper and pencil: challenges in which drawing schemes is necessary to reach the solution of certain mental games (although the most daring will continue to solve them in the head only). Spatial vision: challenges in which one must be able to imagine figures that are intertwined in two or three dimensions.
