A candy bomb is a blocker which must be cleared in a set amount of moves. It is not to be confused with a color bomb. The number on the inside of the candy bomb corresponds to the number of moves you have to clear the bomb before it explodes. When a candy bomb explodes, the turn ends and you lose a life. For $1.99, you can buy a Candy Bomb diffuser to earn 5 more moves to clear the bomb.
In levels, even when all candy bombs are cleared on the board, new ones can drop down. Candy bombs can also be contained in other blockers, like licorice Xs.
Candy Bombs first appear in level 96 and the amount of moves you get can greatly vary (from 50 in level 470 to 3 in level 275). Every cleared candy bomb earns you 3,000 points.
If your board runs out of moves and the pieces are shuffled, the candy bombs will not be shuffled. However, you can move a color bomb to make other combinations, they are not stationary.
How Do I Clear a Candy Bomb?
A candy bomb is colored like normal candies. This means there are two ways to clear the candy bombs.
Through 3-candy combination or a special candy combination.
A candy bomb can also be cleared if it is affected by a special candy being activated.
A candy bomb can also be cleared by another blocker–you will not have to clear a candy bomb if it is absorbed by a piece of chocolate.
