High Low is a mental math puzzle(sort of) game where you have to make a lot of very simple but quick calculations. If the current number shown on the screen is higher than the last you swipe up, if it's lower swipe down and if it's equal swipe left or right. In the beggining you only get numbers but as you progress addition, subtraction, multiplication and division are introduced. You have a time limit to figure out in which direction to swipe in form of a colour filling up the screen. If you swipe wrong or run out of time, you fail. This game is only on Android and integrates Google leaderboards as well as achievements so you can compete with other people.
