Aiming for the color bomb + striped candy combo easily makes around 20 striped candies set off. Afterwards, just make more stripes on your own to finish.
Before using the combo, make sure there are enough candies that has the same color as the striped candy on the board. If there are 15 or less, it is recommended to allow more candies to drop in and fill up the colors, or just try making another striped candy in a different color.
The candy bombs aren't a big problem. Striped candies can run through meringues and defuse them.
Keep an eye on chipping away at the meringue to free more space.
