This is tip 3 of 4 for Bubble Witch 2 Saga 55.
Level 55 Cheat #3: Don’t panic.
Take your time! In this level you have 35 moves to meet the objective. Since there is no time limit, make sure that you take your time and plan your moves carefully. It is easy to get stuck on a single side. However, if this happens take a step back and look around the board to make sure you are making the most powerful move. Look to see what color the upcoming bubble is too. This way you are less likely to get stuck making a useless move.
