Nonagon Pro - Mathematical brain training

Can you get to the target number within 9 turns? Nonagon Pro will test your ability to add, negate, multiply and divide in quick succession and in doing so, train your brain. Work your way up through the different levels by matching the current number to the target number as quickly as possible. The fewer turns it takes, the more points you'll gain. Good luck :)

Nonagon Pro also brings more features and upgrades including:

- More fun levels - Nonagon Pro brings harder levels for a more challenging experience.

- Mini game Widget - Enjoy a quick game via the Nonagon Mini Game Widget.

- New level modes - have fun with all new game play modes including timer mode and much more!

- Ad free (No iAds are presented in the app).
