Pop-a-Pig is a challenge in which you try to drop as many pigs as you can in an endless level.
The challenge can be accessed from the Pop-a-Pig button on the map screen. The button opens the Pop-a-Pig hub which displays the available daily rewards and the amount of pigs you need to drop to win them, the play button to enter the endless level, a leaderboard, and the time left until the challenge resets.
How to play the challenge?
To enter the endless challenge level, you'll need a ticket. You'll get a free ticket daily when the challenge resets. You can also win tickets as a reward from quests and the challenge itself, as well as purchase them with coins.
The level can be played until you run out of bubbles. When you run out of bubbles, you'll have the option to use your coins to get more bubbles so that you could continue to play the level. In case you decide to quit the level instead, you'll need a new ticket to enter the endless level again.
In Pop-a-Pig you'll play the levels with Terence. When you match bubbles six times in a row, you'll get his powerful Smash Pop. The Smash Pop slams into the bubble pack and explodes, helping you to get rid of a lot of bubbles and blockers at the same time. You'll also get additional help from the good blocker bubbles like +3 Bubbles and Bomb Fruits that will fly to the level as you progress further in the level.
The challenge resets every 24 hours. You can see the time left to play below the Pop-a-Pig leaderboard.
