Level 740 is the fifteenth and last level in Marshmallow Mountains and the 325th jelly level.
To pass this level, you must clear 13 double jelly squares in 55 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points. Due to the presence of having 6 colours making it hard to create special candies and reach the side of the board and reach the 5 isolated jellies after the sugar chests been unlocked, it is an extremely hard level.
In addition, six colours makes it difficult to reach the sides of the board. The player must be able to create special candies and use them accurately in order to clear the keys needed to unlock the sugar chests.
The jellies are worth 26,000 points, which is more than the one star target score.
Although enough keys are provided at the beginning, if any key is changed to a striped candy when you create a colour bomb + striped candy combination, the chests will not lose a layer and you have to deal with additionally dispensed keys.
This level spawns sugar drops, when that feature is active.
