The +5 Extra Moves booster gives 5 additional moves to the game when activated while you are playing a level. This booster can be activated only once per game, however, when you fail a level, you can use it again, by buying it. If you fail the level again, the game offers you to buy the booster with an additional booster, but getting more expensive each time you do, you can do this every time you want.
The +3 Extra Moves booster gives 3 additional moves to the level when activated. This booster is activated before you play a level (like coconut wheel, extra time, etc). The only way to get this booster is to receive it as a gift from a friend when you are stuck at a level for at least 2 days. This booster is only available on Facebook.
