In Stack Smash Ultimate you control a ball that has to reach the bottom of a tower to complete the level. However, there are many black blocks that block the way and you have to find a way to get through them.

So, the first thing you need to do is to find a way to reach the bottom of the tower. There is a way to reach the bottom of the tower and it is very easy to do. All you need to do is to jump on the platforms.
