The Original Area Mazes, Volume 2

This volume of “The Original Area Mazes (Volume 2)” was quite enjoyable for me. Given my level of geometric insight (intuition) – which is not impressive – I found that this book was difficult enough for me to be very rewarding (oftentimes rather challenging), and I solved all the 100 problems without any help from the explanations in the back of the book. I had already done Volume 1 of the book with this title. Both books were, for me, an intriguing way to challenge my aging brain. This sort of puzzle book is, for me, the most enjoyable puzzle book I’ve ever encountered. For those who want to test – and maybe challenge – their spatial reasoning abilities and sharpen their elementary mathematical skills, this book might be the ideal one to buy. Solving such puzzles can be a good way of sharpening your thinking skills. It’s challenging and fun. I would recommend it to spatial/logical/mathematical puzzle lovers.

I'm a huge puzzle fan, and I enjoy these more than Sudoku, or any other logic puzzle I've tried so far. Their elegant simplicity is amazing.. no algebra or higher math required, or even decimals or fractions. Everything is simple integer math, and the only equation you need to know is area = length x height. Some of them (the best ones) it just doesn't seem like they've given you enough information to solve, but if you keep at it you finally get that ah-HA! moment. I've spent days staring at some. These are so clever, and fun. Make sure you pick up volume 1 too. I hope there's a volume 3 soon.

As a math teacher and puzzle enthusiast, I am always on the lookout for new logic puzzles to do in my spare time and to share with my students. I came across these new Japanese "area" puzzles awhile ago and purchased a gook at my local bookstore. I really enjoy doing these puzzles but they are hard to find. I was excited to find this second volume of the book I originally purchased. I think these books are the only real source of these puzzles in the United States. I have used them with my high school math students as a warmup and they enjoyed them as well.

Obsessed. Some are a little tricky. Too confusing. They don't make sense. You have to either multiply, add, subtract, divide, all of the above but you don't know which one to do. And when you check your answer and it tells you for example to subtract one from the other, it's not like it makes sense. Anyways I'm thinking it for what it is and it helps speed time at work.

I am into Sodoku, Kakuro, Logic Grid puzzles, this perfectly fits with my hobby. I had so much fun going through them before bed. A few can be tough, but learning some tricks can help. I recommend for a puzzle lover who likes math.

I found these problems to be slightly harder then the first book but just as engaging. I ended up spending an entire Saturday hooked on these problems until I finished the whole book. As a high school math teacher these make great warm ups in my geometry class. My elementary school children have also enjoyed them. You will not be disappointed with these puzzles.

Great puzzles! I am a teacher and I assign 2 puzzles to my students every week. They are 5th graders so we do the 1 and 2 star puzzles, the others would be too difficult for them.

I got those for my 14 yr old and I liked them so much that I then got a book for my high school math classroom. But they never made it that far because I did them myself, so I’ll have to get another one for my classroom!

Interesting problems

Great for starters during lessons. Even sixth formers enjoy!

Pasatiempos geométricos creados por Naoki Inaba. Hay que calcular el lado o el área que falta en un rectángulo usando solo números enteros. Diferentes grados de dificultad. Muy entretenido.

Recebi o produto com um corte na capa. Tirando isso, ótimo livro para quem gosta de passatempos.

A couple of years ago I took the first book on holiday with me; this year I took the second. I started doing 10 a day and then cut down to 5 a day from level 4 up. There are 5 levels of difficulty and by the time I reached level 5, I was at my limits. The puzzles deal only in whole numbers and logic. Often I would spend some time looking at the puzzle before finally spotting the way in.
