Level 300 was the tenth level in Jurassic Jaws and the 136th jelly level in Dreamworld. To pass this level, you must clear 24 double jelly squares in 45 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
Like other four-colour Reality levels, the Dreamworld counterpart always has more colours, making the level much harder.
The mystery candies spawn in the middle column and can block the flow of candies in that column, or possibly other columns if chocolate (when originated from mystery candies) spreads to other columns.
It can be very difficult to reach the jellies, even during moon struck.
The jellies are worth 48,000 points.[1] Hence, an additional 2,000 points is required to earn one star.
