Most of the Jellies are easily cleared, but the ones in the corners can be difficult to clear and so are the ones underneath the Dispensers on the middle row. Keep this is mind and clear them when given the chance.
With candies of four colors on the playing field you shouldn’t have too many problems making special candies. Consider holding on to special candies until you can combine them because of the combination’s enhanced effect.
Ultimately you want to make Color Bomb + Striped or Wrapped candy combinations because this combinations will clear a considerable amount of Jelly.
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 special candies.
Throughout the level pay attention to Candy Bombs and defuse them when you see fit. This shouldn’t be a problem because of their 14-move timer.
