With your first few moves try to spread the Jam just a little. Doing this will increase the chances of it spreading automatically significantly. While it spreads automatically it allows you to focus on clearing the Candy Ice Cubes.
You should focus on clearing the Candy Ice Cubes as quickly as you can. Not only will this allow more candies on the playing field, but it will also make it easier to create special candies. It’s especially the Candy Ice Cubes in the bottom left and right corner that are difficult to clear
With candies of five colors on the playing field you shouldn’t have too many problems making special candies. Try to make as many special candies as you can and when possible combine them to maximize their effects.
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. It would be a waste to miss out on a chance to make a special candy only because you didn’t take your time.
