Level 1,910 is the fifteenth and last level in Kooky Kingdom and the 808th jelly level. To pass this level, you must clear 25 double jelly squares in 20 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
The biggest priority is getting to the candy bomb in 16 moves before it detonates. The sugar keys are stuck on the exteriors of the board, but that is the only way to unlock the sugar chests.
Afterwards, candies will start spilling over to the remainders of the board.
Candy bombs will start spawning frequently, but not in a rate that will flood the board. Use these to your advantage to boost up your score. It's possible that a lucky colour bomb and candy bomb combination will pull you above the one star target score.
