|Level 645||Level 646||Level 647|
Level 646 is the 16th level in Opulent Observatory and the 148th ghost level in Bubble Witch 2 Saga. To pass this level, you must free the ghost and score at least 1,500 points in 9 moves or fewer. When you complete the level, Bubble Rain is activated and will score you additional points.
- This level is hard because it has too few moves even for three colors, so too often you will miss one color to shoot with too much.
- Make matches where ever possible, and hope for a good and even distribution of the colors (it usually isn't).
