I’m excited to announce that my first ebook is on sale.
It’s plainly titled Math Puzzles: classic riddles in counting, geometry, probability, and game theory.

The ebook costs $4.99 and it contains 70 of the best puzzles from the Monday puzzle series. The link above will take you to a website Gumroad where you can pay for the book by credit card. You’ll immediately get a link to download the ebook, and you will also get a copy by email just in case.
This is the first time I’m selling an ebook, so if there are any hitches, please email me immediately (presh@mindyourdecisions.com) and I’ll be happy to solve the problem.
Very important: I should mention the ebook does not contain any new puzzles, so don’t buy it if you’re expecting new puzzles.
That said, the ebook is nice way to read these puzzles, and it would make a perfect gift for anyone who loves math.

Coming soon: Kindle and other versions
Personally I prefer ebooks in pdf format with no DRM. I am guessing you guys would feel the same way, so that’s why I decided to go with direct distribution.
That said, many people prefer to buy things from Amazon and other marketplaces, so soon the ebook will be available for the Kindle and other ebook readers too.
Thanks for all your support!
This part is going to sound sappy, but it’s something I really want to say.
I’ve been writing this blog for nearly 5 years now, and I have to thank you all for all you’ve done. The feedback through email, comments, and shared posts has been amazing and has kept me motivated to keep writing more.
This ebook would never have been possible without all of that support.
