What is Mensa?

According to Wikipedia, Mensa is the largest, oldest and best known high-IQ society in the world. It is a non-profit organization open to people who score at the 98th percentile or higher on a standardized, supervised intelligence test.  Mensa is formally composed of national groups and the umbrella organization Mensa International.   There is an Australian branch of Mensa too.

Entry to Mensa is open to people 14 years of age and over.  To enter you must complete a supervised test comprising of two parts.  One is a verbal test and the other is diagram based assessment.  If you score 98% on one of both of those assessments you will be invited to join Mensa.    You can also apply to join Mensa is you have documentary evidence of your IQ level from a qualified psychologist.

Mensa is a group that believes in keeping the brain stimulated and in their newsletters they always include a crossword or some form of puzzle.    They also publish a great range of books for the general public.

This book is one of them.  It is called Mensa- Exercise Your Mind – Math and Logic Puzzles.   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”

Perhaps you aren’t Mensa material but these puzzles will get your brain working to the best of it’s ability.  This book is well worth the small investment.
