Here is our 3 star walkthrough video strategy for Amazing Alex level 4-25 The Treehouse, also called “Particle Accelerator”. The goal is to have the two balls make contact with each other. The best bet is to bring the right ball over to the left side and hope they touch there.
If you have a different strategy for completing this level feel free to leave a comment below.
this one was difficult, put the plank and slingshot on the right side of the pipes just like the video, now put a plank on the left side of the pipes diaginal with the bottom side pointing towards the star next to the pipethen put the other slingshot to where it points a hair above the star under the ball, shorten up the slingshot so it get the star and goes on the plank(that has the star) above and gets the star and the other balls should go to the other side and hit the ball on the plank, good luck!
