Reflex Ball is a pure test of reaction speed. A ball made of several colours sits in the middle of the screen, and smaller coloured balls fly towards it from above and below. Your job is to keep the colours matched.
Tap or click to rotate the central ball so the colour facing each incoming ball matches it. If an incoming ball hits the wrong colour, the game is over. It starts slowly, but the game gets faster and faster the longer you last. Let us see how strong your reflexes are.
