This is tip 2 of 4 for Bubble Witch 2 Saga 144.
Level 144 Cheat #2: Take out bats.
You need to get to the top of the board but unfortunately, there are bats everywhere. Blast them with a match three whenever you can. Remember, they can not be dropped. They will just fly back to another spot on the board. Best bet is to pick a section of the board and get through it so you can get above another area of bubbles. Once you do reach the top, just do what it takes to drop six bubbles. It won’t matter how many bats are left as long as you get through and clear the six.
