Bows appear randomly in the game as you play, when they appear on your game you should be quite happy as they are a good thing.
First you will get bronze bows and when you match the candies with bows on you will get a striped candy which can be matched in the normal way.
When you have switched the bronze bows you will get silver bows which will give you a wrapped candy.
Eventually having switched the silver bows you will get a gold bow and this is best of all as when switched it will give a party popper which will clear the whole board!
On the left of the game board while the bows are in play you will see a meter which counts down the time available for the bows. Once the meter counts down to the bottom the party is over!
