How to play
Open packs, collect birds, battle and keep your progress safe.
Open a pack
Each pack contains five cards. One pack refills every 60 seconds, up to a natural cap of 10. The fifth card in a normal pack guarantees UC or above.
Packs and guarantees
Open 10 normal packs to make the next normal pack gold. Pulling SR+ keeps your progress; opening gold resets it. Rainbow and black packs open first and preserve gold progress. Every 100 packs opened awards a rainbow pack. Gold: SR 65%, SSR 25%, UR 8%, LR 2%. Rainbow: UR 85%, LR 15%. Black packs contain extinct LR birds only.
Animation controls
Enhanced animations are on by default. Turn them off to show results immediately. Daily tasks and sign-in rewards are no longer offered.
Your collection and the public guide
The collection in the top navigation contains your own cards, with filters, sorting and groups. The public field guide in the footer can be read without collecting any cards.
Battles and expeditions
Use your cards in solo battles, team battles, daily boss raids and expeditions. Solo battles last up to 30 turns. Teams support first-to-three and survival. Expeditions require five different bird species. Rarity and combat values are game mechanics.
Backups and cloud sync
Manage saves in the footer offers local files, password-encrypted backups, and Google or email-code cloud login. File restoration merges cards without adding resources twice. Account cloud sync asks you to choose when progress differs, keeping the other version as a recovery copy. Keep backup file passwords safe. Bird calls are available for some species.
