Can you get to the target number within 9 turns? Nonagon 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 :)
