In the field you see all kinds of coloured dots: pink, blue, yellow and green. You have to move dots of identical colours towards each other and then click to receive points. Don’t touch dots of other colours, as the game will be over as soon as you do this. The further you get, the harder it becomes, as the number of dots increases. This means that there are more dots to collect and that there’s less space in between, which makes it harder to maneuver.
