Who is Naoki Inaba?
Naoki Inaba is a prolific Japanese puzzle author of over 400 original logic puzzles. Inaba has a lovely website full of free PDF puzzles. The only issue is that the website is entirely in Japanese. His puzzles have been featured in both the New York Times and The Guardian.
Since his puzzles have so much potential for use in the math classroom, I have been working the last few years to translate these puzzles to English and format them for classroom use. I hope you find these puzzles to be as inspiring as I do.
