The game tests your strengths in colour and eye coordination.
The dots falling from the top of the screen need somewhere to go. If they match the colour of the bottom bar, let them fall. If they do not, swipe them right off the screen. However, at ANY time, the bottom bar may change colours - so keep alert.
Each correctly matched dot will gain you +1 point. If you drop the wrong dot, the game ends. The game gets harder, and the dots fall faster as you progress.
