This is tip 2 of 4 for Bubble Witch 2 Saga 117.
Level 117 Cheat #2: Make matches that will take out multiple bubbles.
The best way to get rid of all of the infected bubbles is to aim for the bubbles that they are attached to. Continue to use this technique as you continue to work your way to the top of the board. Before shooting a bubble look around the board to make sure that it will do the most damage. Not only will you make your way to the top more efficiently but you will also save your moves for later use.
