Level 371 is the 1st level in Episode 21 and the 125th classic level in Bubble Witch 2 Saga. To pass this level, you must clear 6 ceiling bubbles and score at least 4,000 points in 32 moves or fewer. When you complete the level, Bubble Rain is activated and will score you additional points.
- This level is quite easy. It introduces a new blocker type, bubbles bombs, that will produce a row of black holes when expired before dropped.
- Normally, you only can drop one bubble bomb before it expires, and the second one will go off. Try to get the left one, as on the right there is a Zen Bubble and a Line Blaster to clear the row of Black Holes.
- At the top, you need a similar strategy: Make the Zen bubbles next to the row of Black Holes explode to clear the ceiling.
- This level is a tutorial level that the player can learn how bubble bomb work.
