Community Insight:
Originally bought the paperback book at a farmers market. Then played online until it was not kept updated. So glad to have it back.
Visually takes some getting used to, but a neat concept and a smooth app.
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 we like these more than sudoku. We think they are more engaging and challenging. But the easier level puzzles make for quick puzzle fun. We highly recommend this to anybody who enjoys puzzles like sudoku. You might find youll end up feeling like us in liking the OCTO more.
The next logical step for puzzle lovers who have played too much Sudoku and are looking for their next challenge! Fun to play and more challenging as the levels bump up.
Im so happy theres an app now! We started doing the Octo in our college paper and ordered the books after we graduated. Thank you for keeping this great puzzle fresh and accessible.
OCTO! The complexity makes all the difference. Great interface, easy to use, and quite addictive. Thanks for making this game into an app.
