Whether it’s clearing Licorice Locks or Marmalade, it doesn’t matter. What matters is that you clear blockers as quickly as you can. Since it’s a bit more difficult to clear Licorice Locks you shouldn’t miss out on opportunities to clear them.
While you’re clearing the Sugar Keys also focus on making special candies that will pop the kernels. Although you can collect Ingredients without popping the kernels by moving the Ingredients to columns without kernels, it’s a lot easier if you pop the kernels first and then bring down Ingredients.
As for the Coconut Wheel, just roll it towards the left or right of the playing field. Activating the Coconut Wheel on its own works just fine but it’s better if you manage to combine it with a special candy.
Match candies near the bottom of the playing field as often as you can. Doing this will shift the largest amount of candies, hopefully start a chain reaction and create new opportunities to make special candies. While matching candies at the bottom it can be easy to ignore making special candies at the top of the playing field. So pause after every move and glance at the entire playing field to see whether you can make special candies.
