To enter Lucky Balloon tap the balloon icon located on the right side of the screen above the Tasks button. Pick a balloon to discover various rewards, but beware of the pigs that are hiding. They are waiting to take away the rewards! Pigs have trouble getting to floors number 5, 10, 15 and so on, so make sure to use it to your advantage!
In case where a piggy is met when revealing rewards, it will take them all away. You can recover the rewards with Gold Coins or by watching an advertisement. If you decide to ‘Give up’ when meeting a pig, then the pigs will take away all the rewards.
As long as no pig is revealed from behind a balloon, you can claim the rewards by tapping the ‘Quit’ button at the bottom of the game screen.
A single free daily attempt is available. However, further attempts will require some Gold Coins.
