Math 15

Math 15 is an easy way to improve your brian. You are not only playing a game but also having fun while you exercise your mind. How it works: You have to find different numbers from 1 to 9 with the sum of 15 without repeating the numbers (8 7 is possible, but 7 4 4 not). For each correct sum you'll earn points. 5 points for each number you used to sum 15 (8 7 gives you 10 points but 8 5 2 gives you 15 points). If you find any difficult, you can press the start button and it will generate new numbers. On the Scores screen you can check the best 5 results of the best players (Beta phase).
