In Guest Star challenge you play levels with a different Guest Bird every day to earn rewards.
How it works?
In this challenge you complete randomly selected levels with a Guest Bird to earn stars and gold feathers. The stars you earn from playing the levels will be added to a progress bar with reward milestones. When you have earned enough stars to reach those milestones, you'll be able to collect the rewards. The gold feathers will count towards a bonus prize.
Playing the Guest Bird levels requires a ticket. You'll get free tickets to the challenge, and you can also earn them as a reward, purchase them with coins or watch a video to get one for free.
You can access the Guest Star event from the Fun Stuff menu. On the event screen you can see which bird is currently visiting, the rewards and star progress required for the unlocking them, and the Play button to enter a level with the Guest Bird.
The Guest Bird is only available when playing while online.
In addition to stars, you can obtain also gold feathers when playing with the Guest Birds. The score bar at the top of the level displays a small feather, when your score on the level reaches the feather and you pass the level, you'll receive a gold feather. The gold feathers count towards a bonus prize, and you can see your progress towards the prize on the event screen.
