The Secret of the Twelfth Coin

The stories alone have entertainment value: "Five petty criminals don't trust each other." - "In a large terrarium, some chameleons live quite happily." - "In front of you are twelve coins that all look the same and also all weigh the same - except for one, which has a different weight." What is fascinating about the puzzles in this book, however, is above all the flash of inspiration that leads to their solution. It's great to share in such flashes of inspiration. And this is true even if you can't solve a problem at all or only partially. Each chapter begins with a classic and ends with a particularly challenging brainteaser. Often, successive tasks have something to do with each other. Great fun and a turbulent mind-fest for all puzzle beginners, puzzle professionals and puzzle addicts.
