1 Second is an addictive game that test the limits of your brain. Your ability to make quick decisions and to focus may come in handy. In each level you get only 1 second to select the matching color to the main color out of 3 colors. Although it looks simple, it can drive you crazy when your brain can't handle the speed and the colors. When you level up, color options get more similar so they will be harder to match. The quicker you select a color, the more score you get.
