This is tip 2 of 4 for Candy Crush Soda Saga 13.
Level 13 Cheat #2: Make striped candies..
Striped candies aren’t too difficult to make on this level, especially in the top area of the board, where there is a large amount of candy and hardly any blockers. Look for any available matches of four, make a striped candy, and set it off vertically to clear a column of blockers down the board. Vertical striped candies will do the most damage here, since you wanna clear as much of the bottom blockers as you can.
