Michelle: Got this bc my husband and I love riddles and brain teasers- that feels lame even typing but there it is. This book got really good reviews and a lot of reviewers commented that the contents would be challenging. Well… here’s the thing. They reuse a LOT of scenarios and some of the “puzzles” are just downright ridiculous. Like you have to read the answer and then realize you never would have gotten it bc they throw in strange little nuances that are far fetched and ridiculous. We still mull over some of these in the evenings but w a grain of salt. Don’t want to waste too much time on something that will be fruitless. It’s an ok book, I guess it just depends on what you’re looking for.

Vivian M.: Bought this for my disabled daughter although no one a group home will take the time to read it to her or hold it for her to read herself, it was a title they drew me to it. One of her favorite sayings is always, but of course! LOL

Israel Drazin: This is an easy to read and easy to use collection of 78 brainteasers and riddles. To get the answer, all one has to do is click the side of the question. The questions are not complicated. Examples include: Why are manhole covers round? How far can a fox run into a woods? The questions prompt us to think and reach a moment of clarity where we say "of course!" Each question is unique, nor repetitions. No complicated math of a need to have a high-level vocabulary. It is a fun book, great for parties or while sitting alone.

Rich H: Some great brain twisting puzzles in here. Starts off easy to get you into the swing of it, then comes up with some right brain melters. loved it all the way! If anything, it's a bit small and you get to the end quite quickly. So savour each puzzle - if you can't answer straight off, sleep on it. Once you know the answer you can't go back, and they really are 'Of Course!' and 'Oh yeeeaahhh' once you know ;-)

Matty_son: Die Denksportaufgaben-Sammlung ist hervorragend. Auch die Aufgaben von Martin Gardner kommen bzgl. der Lösbarkeit ohne tiefere mathematische Kenntnisse und der Eleganz vieler Aufgaben an diese im Schnitt nicht heran.

Die Aufgaben sind von leicht bis schwer sortiert, und bei den letzten kann man manches Mal vermute, dass sie unlösbar sind - Irrtum!

Ein paar Beispiele bzgl. der typischen Aufgabentypen: Das Ziegenproblem, Aufgaben mit Lügnern, mehrere Aufgaben mit Hüten (man sieht die anderen, aber nicht seinen eigenen) usw.

Es gibt keine sprachlichen Aufgaben - im WEsentlichen reine Logikaufgaben.
