Keep tapping the red block to reach a high score! SpectroTap is a game of speed and agility. You begin with four seconds to tap the red block on the grid. Every time you click the red block, you are given one point, you get more time, and the red block jumps to a new spot. But watch out! The game will keep getting faster and faster, and you'll be awarded less and less time for tapping the red block. If you tap the wrong block or run out of time, you lose.
