This is tip 2 of 4 for Bubble Witch 2 Saga 55.
Level 55 Cheat #2: Avoid the poison swirl bubbles.
The poison swirl will take away your bubbles. In order to avoid wasting moves, stay away from them. If you are aiming for a match near them, make sure that you have it perfectly aligned. Remember, the swirls are also along the sides, making it much more difficult when trying to reach the top.
