color rush is a browser-based arcade game where your reflexes are put to the test as you guide a moving ball (or other object, depending on the version) through various color-coded obstacles. The twist? Your object changes color periodically, and to keep going, you must only pass through matching colors.

It might sound simple at first,  and it is easy to grasp,  but as the game speeds up, it becomes a frantic battle between your eyes, brain, and fingers. With each successful match, you score points and advance further. One wrong move, and it’s back to the start.
