Is there a good book on riddles (preferably, math riddles)?

What level of maths are you comfortable with? Ex. 10-12th, undergraduate, post grad?

I know enough of algebra, P&C, and stats. Any specific book of Martin Gardner? Apart from math, if you have any other suggestions those are welcome too. I am essentially looking for a "brain-teaser" kind of a box which forces you to think a bit for the solution.

Don't have any brain teaser recommendations but if you are looking for other mathematically oriented books, "Infinite Powers" by Steven Strogatz is a great book.

Thanks @faint-energy-11966. This book is already in my wish list 🙂 A suggestion from my side is "Our Mathematical Universe", if you are also interested in such books.

If you like Euclidian geometry, try this out - https://play.google.com/store/apps/details?id=com.hil_hk.euclidea&hl=en_IN&gl=US
