Starting Bubbles: 50
Recommended Potions: 7 extra Bubbles, 3 holes in the ceiling, RB Bubble
Points needed for 1, 2, 3 Star: 105, 140 000, 180 000
2 Lock Bubbles(1 chains)
You need to use your bubbles in the Cauldron with care, as they run short very easily. This means that you should unlock the chain ASAP! You can place some strategic bubbles under the black row endings to help you get matches after the chain is broken, that is the secret for a high score on this level.
At the middle part you need to work your way up to shoot a matching bubble(or RB bubble) above each of the black bubble rows. When you have taken down both of them, you’ll see the ceiling soon. Hopefully you then have enough Bubbles left to break it.
