Glitches

In Smash Hit, there are multiple glitches that can happen. Here is a complete list, and their respective images.

Random Rooms Glitch
This glitch was discovered on the multiplayer game-modes update. If you close the game while in checkpoint 2 mayhem mode stage 1 part 2 (2-1-2) and Checkpoint 2, stage 3 or 4 (2-3 or 2-4), after this the checkpoints are all jumbled up. The mayhem boss can appear somewhere in endless after one or more re-opens.

However, the score/distance will not be changed by this. The Checkpoint subtitle is incorrect though, the game crashes in versus or co-op mode and you fight the Bosses again in mayhem mode. This glitch is very unusual, but also the easiest to get, and the most accessible.
 * Rooms (and sometimes their parts) are connected together randomly, so you might see big walls, and other features you might not usually see, obscured by the stone blocks in the actual game.


 * Each "part" is considered a room in it's own right, so halfway through a 2- or 3-part (Checkpoint 10 only) room, it might suddenly go somewhere else.
 * The bar above if activated before the glitch happens is faster, indicating that the glitch works.

How the Checkpoint subtitle works:

Suppose you are in Checkpoint 2 Stage 2 and the glitch happens.

Though you are in a different checkpoint (e.g. Checkpoint 7,), you were previously in Checkpoint 2, so Checkpoint 3 is used as a marker. The next marker is Checkpoint 8, although you are in Checkpoint 5, really. The marker is from the previous (real) checkpoint you were in before. It is tricky to understand, but reading the table, you might understand better.

Repeating Glitch (Room Of Purgatory)
There is also a automatic repeating glitch. This is a glitch only occurs via the wrong checkpoint glitch although this only occurs at a distance of 30000+, because of that , it is referred as the Room Of Purgatory. 

Now Entering Endless Mode Text Glitch
This is also a automatic glitch. This can only occur via the wrong checkpoint glitch and it is extremely-extremely-extremely rare. Usually occurs before a distance of 12K.

Disappearing Crystal Glitch
Sometimes, in a Random Rooms glitch, the crystals might not appear where they should be. This is most evident in pedestals, blank spaces, etc, anywhere that can hold a crystal.

Reset Powerups Glitch
This is an automatic glitch. If you close and reopen the game after you acquire a powerup, your powerups will not save, same with restarting from a checkpoint after you had powerups, even those you acquired before the checkpoint.

Disappearing Room Glitch
Though extremely rare, rare on zen mode and possibly on only some devices , the Disappearing Room glitch can occur at any time , although it is extremely-extremely rare for blank door before the disappearing room glitch occurs. First, the next stage you enter will not have anything visual, except the balls you throw, powerups, shadows, the door outline, and the background color, there is also a blank door at the end. After passing this level, the next level might consist of nothing. No solid surfaces, no objects, no music... just the endless abyss of echoing after throwing a ball, and a white background. 

Stop Glitch
The stop glitch can randomly occur anywhere, but it usually happens at the beginning of a stage. Sliding objects and your progress will idle, while balls and objects with gravity continue to move. This likely occurs because of music failing to load, thus you can also cause this to occur by playing an alarm on iOS devices in the middle of a game. Exiting (not closing) and resuming the game will resolve the alarm-activated stop glitch. A video is here :

The only requirement for the stop glitch is to make the music not play, so causing lag while Smash Hit loads a different stage might also cause a stop glitch.

An easy way to do this is to continue from Checkpoint 9 and throw a bunch of five-balls. This causes a lot of lag, but don't stop until the music stops playing or it appears that the camera has stopped. (It might be a good idea to turn sound effects off.) Don't hesitate to throw all of your balls before the camera stops, since there are enough crystals to give you more if you run out. If you have enough balls, you will most likely trigger the glitch since the music has failed to load due to lag.

Lose in the Credits/More Games Glitch
If you tap "more games" or “credits" in versus and co-op mode, by throwing balls you can drop to zero and lose.

Infinite balls glitch (Old versions)
In some older versions of Smash Hit, it was possible to retain your balls and multiplier status after restarting the stage. To reproduce the glitch, you need to start from a the Introductory Stage, close the game and reopen it, then click resume. Then collect some crystals and restart the stage. You will notice that your ball count has been preserved.
