Pet Rescue Saga Boosters
Use the Boosters by clicking on them when they are coloured while playing. The interesting one, is the one that you can buy with in game Coins , the Block Buster Booster.
Coins is a currency available only at Facebook, not in the mobile version at all.
Block Buster Booster (Hammer, Pickaxe)
The Block Buster Booster looks like a Hammer or a pickaxe and you use it to smash one unwanted block. The Block then will disappear from the game giving you better opportunities to clear the level with a great score. The Block Buster booster costs 3000 Coins per purchase or 9 Facebook Credits. You get 3 Block Buster Boosters in one set when you buy one.
Block Buster Boosters can be found as the booster you build inside the levels in episode (30) Level 418 and higher.
You can not use coins to by a Block Buster Booster while you are playing an actual level, but you can buy it with Facebook Credits while playing. If you want to use the Free coins to purchase Block Buster Boosters, you can do so by purchasing the Block Buster Booster before you enter the level.
The Color Pop Booster (Balloon)
You get 3 Color Pop Boosters for free when they are unlocked and they also appear on many levels for free. If you want to use them on Levels that haven’t any Balloons in them you need to buy them.
