Checkpoint 9 is the tenth and ninth official checkpoint in Smash Hit.
The theme focuses on geometry, with color schemes of green to light yellow. It also introduces rotating glass cubes.
In the beginning of this stage, there will be two infinite ball power ups. There will just be hollow glass cubes, and octahedron crystals that worth five balls each until the end, where there will be two crystal stars worth ten balls each.
At the beginning of Stage 2, you will find an "Explosive Ball" power up. The screen will then start to rotate a few seconds later, and you will shoot spinning screen glasses, propeller blades, and fans with five blades.
From the beginning of the zone until the very end of the level, there are sai-shaped pieces of glass and angled pieces of glass, then in the middle of the zone, there are two big hollow glass cubes with two crystal stars. Then the room rotates. The very end has a swirl leading to a door which leads to Checkpoint 10.
- Checkpoint 9 was the last level before Endless Mode in versions of Smash Hit before 1.2.0, which two levels were added.
