During the first stage Bottles will only spawn from the Dispensers, so until you pop the very last Bottle make sure to match candies below the Dispensers.
The easier way to pop the Bottles, other than matching them, is by making Jelly Fishes and activating them. It should be easy to make Jelly Fishes since there are only candies of five colors on the playing field. While you’re popping the Bottles the orange acid will clear the Licorice Links and Candy Ice Cubes for you.
As for the Coloring Candies, there is no reason to hold on to them and it’s difficult to combine with a special candy since they’re located at the edge of the playing field. That’s why I suggest you just activate them as soon as you can.
During the second stage you have to move the Bears on the left side to the bottom and the ones on the right side to the top. The only thing you need to be careful of during this stage is that you don’t accidentally clear the wrong candies when you activate Striped candies.
Other than that, just clear the Licorice Swirls as soon as you can and clear the Candy Ice Cubes necessary to bring down the Bears using special candies. And always check whether you can match match candies adjacent to Candy Ice Cubes and Licorice Swirls that’s a quicker way to clear them then relying on special candies.
