Use your knowledge of area to solve each area maze puzzle for the missing length or area. No fractions are allowed in these fun logic puzzles from Naoki Inaba!
Looking for more printable geometry puzzles for your classroom? Here’s just a few examples of other geometry puzzles I have shared!
Puzzle Creator
Area Mazes are the creation of prolific Japanese puzzle creator Naoki Inaba who has created over 400 different types of logic puzzles.
In recent years, these area mazes have become quite popular in the United States. This hasn’t always been the case.
I first learned about these puzzles from a tweet from Lisa Bejarano. At the time of her tweet, you could only really get your hands on a large number of area maze puzzles by ordering them from Japan.
Area Maze Puzzles are also known as “Menseki Meiro Puzzles.”
Area Maze Puzzle Books
Naoki Inaba has published several volumes of area maze puzzles.

The goal of the puzzle is quite simple: figure out the value of the question mark. One caveat: you are NOT allowed to use fractions in your solution. All of these puzzles can be solved using ONLY whole numbers.
Area Maze Example Puzzle
I really like the example puzzles provided in this article from The Guardian by Alex Bellos. In fact, Alex Bellos actually wrote the introduction to Inaba’s The Original Area Mazes book.
To solve the puzzle above, you’re going to need to think outside of the boxes provided.
Alex Bellos offers up this hint in his Guardian article. If we form another rectangle as shown below, we can easily find its area.
After all, we know its length and width. We can also realize that the rectangle on the left and the two rectangles on the right both have the same area.
If they have the same area and the same height, they must also have the same width. Isn’t that an incredibly satisfying feeling?
Want more puzzles to solve? I know I do! Keep reading for some sources of free area maze puzzles to keep you busy while you wait on a copy of Inaba’s full book of puzzles to arrive at your doorstep.

The Waterloo Region District School Board has a page of puzzles and riddles for elementary students to tackle. They feature several area maze puzzles as well as questions and prompts to use with students as they are tackling these puzzles.

If you have a free account on TES, there is a free printable of area maze puzzles to use with your students.

Transum (an all around lovely site for math teachers with tons of free resources) has four levels of area maze puzzles for students to work through. They are even self-checking!

Area Maze Variations

These 3-D area maze puzzles are from Naoki Inaba himself! I found them in a blog post by the New York Times.
Puzzle Solutions
Puzzle solutions are available on a password-protected solution page. I do not openly post the puzzle answer keys because one of my goals as a resource creator is to craft learning experiences for students that are non-google-able. I want teachers to be able to use these puzzles in their classrooms without the solutions being found easily on the Internet.
Please email me at sarah@mathequalslove.net for the password to the answer key database featuring all of my printable puzzles and math worksheets. I frequently have students emailing me for the answer key, so please specify in your email what school you teach at and what subjects you teach. If you do not provide these details, I will not be able to send you the password.
Not a teacher? Go ahead and send me an email as well. Just let me know what you are using the puzzles for. I am continually in awe of how many people are using these puzzles with scouting groups, with senior adults battling dementia, or as fun activities in their workplace. Just give me enough details so I know you are not a student looking for answers to the puzzle that was assigned as their homework!
I was also excited and did a little bit of research after seeing Lisa's post. I have tried out the Android app and it's a little clunky, but there are lots of available puzzles. I am planning to use them as warm-ups. (Maze Monday?)
I like it!
I just spent an hour on the iPhone app solving these puzzles. I am completely hooked. The puzzles focus on logic, proportional relationships and most of all number sense. I definitely see them having a place in my classroom.
I downloaded the app and spent some significant time on it, too!
I think I'm going to use this as a first day of school activity for Geometry. I think I'll also bring them back as we start to do 2-column proofs to remind them about perseverance, and how we might have to alter our thinking to reach the end goal of proving something.
Please blog about how it goes!
I'm totally going to start using these at the beginning of the PD I deliver to my math teachers! It'll be a great warm up and something for them to do while we're waiting for the stragglers.
Great idea!
I bought the book after seeing Lisa's post-and I loved reading your posts on it! Thanks for the links to the previews-it's so cool that the language doesn't matter in math. I also love Sarah Millard Lanahan's idea for PD!! I teach adults at night and can't wait to use these with them as well as my middle schoolers. Keep blogging-I love what you're doing!!! @debboden
Thanks Debbie!
Using these today! So excited – keep forgetting about them and then keep resdicovering them through endless reading of your blog – which is one of my favourite things! Thanks for these 🙂
