Love this game

Originally bought the paperback book at a farmers market. Then played online until it was not kept updated. So glad to have it back!

Better Than Sudoku

These OCTO Puzzles certainly have a learning curve right off the bat. But once you get the hang of it, they end up being a blast. Personally I like these more than sudoku. I think they are more engaging and challenging. But the easier level puzzles make for quick puzzle fun. I highly recommend this to anybody who enjoys puzzles like sudoku. You might find you’ll end up feeling like me in liking the OCTO more.

worth the wait

I’m so happy there’s an app now! I started doing the Octo in my college paper and ordered the books after I graduated. Thank you for keeping this great puzzle fresh and accessible!
