Level 2457

Difficulty

 * The locked sugar key and key dispenser is separate from the main board.
 * Popcorn is surrounded by chests, so the resulting colour bomb can't be swapped or combined with special candies until the sugar chests are gone.
 * At least four vertical stripes are required to get rid of all sugar chests, one to remove the lock, then three more for the three keys that are required to unlock the chests.
 * Four colours makes it easier to create special candies.

Trivia

 * This will be the first level where popcorn is completely surrounded by sugar chests.
