Your first objective should be clearing the Chocolate as quickly as you can. With the Chocolate gone you won’t be wasting moves clearing the Chocolate the keeps spreading and making special candies will become easier.
To gain points use Color Bomb candies to defuse Candy Bombs. The more candies you clear with the Color Bomb candy the bigger the boost will be. That’s why it’s important you clear the Chocolate as quickly as you can, preferably before you defuse the first Candy Bomb with your Color Bomb candy. Combining a Color Bomb candy with a Striped or Wrapped candy will barely make your score move. Only make this move if you intention is to clear Chocolate.
With candies of five colors on the playing field you shouldn’t have too many problems making special candies. Still, take your time and don’t miss out on opportunities to make special candies. Consider holding on to special candies until you can combine them because of the combination’s enhanced effect.
Match candies near the bottom of the playing field (or as low as possible) as often as you can. Doing this will shift the largest amount of candies. This in turn will hopefully start a chain reaction that will create new opportunities to make Color Bomb candies..
While matching candies at the bottom don’t ignore the Candy Bombs at top of the playing field. Pause after every move and check whether you can defuse Candy Bombs.
As for the Candy Frog, you can pretty much ignore it. If you manage to feed the Candy Frog hold on to it until you have to use it to defuse a Candy Bomb that’s about to explode.
