This online game is a kind of test for the development of reaction. There are five circles in front of you, four of them red and one green. Your task is to move the mouse cursor over the green circle as quickly as possible, which, by the way, constantly moves and red appears instead. Avoid hitting the red circle with the cursor, as you will be penalized for doing so. Over time, the task becomes more complicated, as the circles start moving faster and more unpredictably.
