Test your powers of thinking with over 500 challenging problems and puzzles. "Mensa" presents a collection of problems that require either logical deduction or lateral, imaginative thinking to solve. To help you, the sections are divided so that you know what kind of thinking process is required. To hinder you, "Mensa" has come up with the most varied collection of problems, puzzles and conundrums you could wish for. Mensa, the international high-IQ organization, is known as a society for people who pride themselves on their ability to solve problems by the relentless application of intelligence. Logic is king in our world, but there are other kinds of problem that cannot be solved by logic alone, problems that require a few moments of consideration before an answer can be found.

Store Description

In 2002, World of Books Group was founded on an ethos to do good, protect the planet and support charities by enabling more goods to be reused. Since then, we've grown into to a global company pioneering the circular economy. Today, we drive the circular economy through three re-commerce brands: - Wob: Through Wob, we sell. We provide affordable, preloved books and media to customers all over the world. A book leaves our collection of over seven million titles and begins a new chapter every two seconds, enabling more goods to be reused. - Ziffit: Through Ziffit, we buy. We give people around the world the opportunity to contribute to the circular economy, earn money and protect the planet, by trading their unwanted books and media. - Shopiago: Through Shopiago, we help others. By sharing the technology that has grown World of Books Group into the business it is today, we?re helping charities increase revenue and reduce waste through re-commerce.
