The following table of gravity speeds was observed and later found to be stored at $808E (offset $099E in the iNES format ROM):
| Level | Number of frames |
|---|---|
| 00 | 48 |

In Marathon (called A-TYPE), when the player line clear (startLevel * 10 + 10) or 100 lines, whatever comes first, the level advances by 1. After this, the level advances by 1 for every 10 lines.
- Start at level 5, advance to level 6 at 60 lines, advance to level 7 at 70 lines.
- Start at level 12, advance to level 13 at 100 lines, advance to level 8 at 80 lines.
