Checkpoints

Checkpoints are places in the game that allow you to continue after you run out of balls in Smash Hit. They can be used in Classic Mode, Mayhem Mode, and Training Mode. Restarting from checkpoints requires the Premium Version. When a ballcount is higher than the original ballcount of a checkpoint, it is saved, and (the circle 〇 would have a number inside it) will appear in the Smash Hit font. See the image of Checkpoint 3:

Repetitions of endless modes

 * 2nd endless mode (20,000-28,000)
 * 3rd endless mode (28,000 and above: due to a glitch, it would have ended at 36,000 for this endless mode)
 * Repeating Room Glitch begins at 30,000 (or if all rooms of the 3rd endless mode are completed), avoiding any more repetitions. (This means that all rooms beyond the 3rd endless mode are hypothetical.)

Importance
Checkpoints allow the game's progress to be saved and the distance conventionally measured, as well as organizing the rooms into groups based on their gradient colors.

History
Smash Hit has had many revisions of its checkpoints, as well as many scrapped checkpoints.
