Boosters are a useful asset in tackling levels for Candy Crush Saga and sometimes can be the perfect tool to hit those hard levels.
There is a range of boosters available in the game which are explained both in-game and in articles elsewhere in this Helpcentre, so take a look around and you can find some great tips.
It's important to know that there are two basic types of boosters...
Some boosters are activated on the pre-game screen 'goals' screen. This is shown before you enter a level and will tell you what you need to achieve to pass. Beneath the goal is the listed boosters you can take into the level to help you out. For example, the Color Bomb booster lets you start the level with a Color Bomb already placed randomly on the game board.
Not all boosters can be used on all levels, so make your choice wisely before you start.
Pro Tip: Sometimes you'll find ways to win 'Unlimited' boosters, which add a specific feature to your game without any worries about quantity. It will continue to deliver the booster for the duration of the Unlimited phase and end when it expires. Be aware, these will only add while you're playing and the timer will tick down while you're away - so push through those levels while you have that extra help!
The second type of boosters are those you use 'as-and-when' in the game. A great example of these is the Candy (Lollipop) Hammer.
You can select them in the level you're playing and use them whenever you need. This second type of booster (available in gameplay) are shown at the edge of the screen, so you can see which and how many you have at any time.
If you don't have a booster, tapping it will open the window to show you how much it costs in Gold Bars to by that booster, just in case you need to top-up on that extra helper!
