Tap the circles as quickly as you can. If you're too slow, the game is over! Can you reach the top of the leaderboards and unlock all of the achievements?
Each circle has a different effect:
Red Circles - Each tap gives you 1 point. All red circles must be pressed to advance to the next round. You must be quick as your time is limited.
Green Circles - Tapping a red or blue circle turns them green. If you tap a green circle, you lose 10 points.
Blue Circles - Tapping a blue circle gives you three points, but they don't help advance to the next round. Are you going to take the risk?
Black Circles - Tapping a black circle causes you to instantly lose the game. Be careful!
