Classic vs. Blitz in Glow Spin
Classic is an endless mode with increasing difficulty, while Blitz is a timed configuration with a choice of 60, 120, or 300 seconds.

What changes between the modes?
| Mode | Session shape | Difficulty change |
|---|---|---|
| Classic | Endless | Increases as play continues |
| Blitz | 60, 120, or 300 seconds | Six equal sections move from four to nine segments |
The mode choice is about the kind of session you want to play: open-ended Classic or a defined timed challenge. The Blitz duration article describes the three time choices in more detail.
