Bubble Witch Saga Eternal Isles 18 Level 4
You take the rainbow Bubble Potion into the game, because you want to ensure that you get rid of the bubble “spikes” at the bottom very fast, like in this Pic at your left hand side here. I used only six bubbles to get to the middle part and had absolutely no problems getting the aims above the viruses needed to drop the screen and see the ceiling. I wait as long as possible before I start to shoot at the Mystery Bubbles, to avoid the sad ending of a Bomb taking one of my hearts. This also gives me lots of green Spiders to drop the ceiling on and therefor quite often 3 Stars!
