This blocker is one of the most hated elements in the game, because it can cause an instant loss if it's not removed in time.Candy Bombs can be any of 6 possible colors and they have a number on them.
The number corresponds to the number of moves you have left, before it explodes.When a Candy Bomb explodes, the player loses the game.
The number on the bomb will be reduced by one with every move, even when the bombs are under Liquorice Locks, in Marmalade, or inside Sugar Chests. In this case, the player can clear them after the lock is removed.
It can be removed if it's match with other candies of the same color or through any special candy's effects reaching the blocker.
If a Color Bomb clears the same color as some of the candy bombs on the board, the player can receive massive points.That's why, if there are Candy Bombs on the board on timed and moves levels, Color Bomb/Candy Bomb is the combination you should look for.
Candy Bombs can be generated from Candy Cannons and they can come out of Mystery Candies.
The Candy Bomb's timer can be increased by 5 with the help of a booster, called the Bomb Cooler.
