We offer you several problems. The number of problems (levels) - 15. Problems are always given in random order. Time is the most important. You have to solve the problem as quickly as possible. The score depends on your speed. Wrong answers result in penalty time, and as a result - a loss of points. There are three difficulty levels: Easy, Medium, Hard. Types of problem: - Mathematical problems (addition, subtraction, multiplication, division, comparison) - Sequence (numbers, letters, pictures, colors, dots, shapes) There is a High Score Table (local). You can submit your score to the Game Center. The number of problems will continually increase. Thank you for your attention to the application!
