The idea is simple, to score points you just have to land the rocket on the platform with as much fuel as you can so you can get the maximum number of points for that level.
(If you land it with just a little bit fuel left, you would get a few points, but if it has much fuel you would get more points.)
Also try to get the yellow boxes which will get you 10 points bonus. But also avoid the red boxes because they will drain your fuel very fast.
You can also customize this game by changing the aspect of the rocket or of the platform or you can change the background.
Also it is for free, and without any ads.
