A single dim star-egg hums in the dark. Drag two matching eggs together and they hatch, merge, and evolve — climbing from fragile sparks all the way up to the legendary Celestial Phoenix. Grow your sanctuary at your own pace.
Merge, arrange, explore — each part of the game unfolds at your pace with no timers and no pressure.
Tap Star Font to add a new egg to your nest. Every egg is a potential cosmic bird waiting to hatch.
Drag two matching creatures together. They merge into the next evolution, growing stronger and rarer.
Place matching elements side by side to boost stardust income. Ring a cell with the right element for rare branch evolutions.
Fly Sky Run, send expeditions, complete daily quests, and fill your codex with every creature you discover.
Every creature belongs to an element. Place them wisely — some evolutions only appear when you arrange the nest just right.
The very beginning. A dim egg humming with the faintest cosmic light. Everything starts here.
⭐ Stellar elementA radiant songbird trailing ribbons of northern light. Its wings shimmer between teal and violet.
❄️ Aurora elementIts tail feathers hold the colours of a forming galaxy — each eye a distant star cluster.
🌌 Nebula elementThe rarest of all. Born from the collapse of a dying star, reborn in every cycle of the cosmos.
☀️ Solar elementA gentle giant that drifts between star systems, humming frequencies no other creature can hear.
🌑 Void elementLeaves a glowing trail wherever it flies. Its antenna can sense the gravity of distant planets.

Your home base — merge eggs, arrange elements, unlock branch evolutions, and watch stardust flow in passively.
Take a creature for a flight through asteroid fields, nebulae, auroras, and black holes. Each pilot has a unique ability.

The Application does not collect, log, or store any personal information when you download and use it. Registration is not required. If the Application is used with an active internet connection, technical protocol data (such as your ephemeral IP address) is transmitted to facilitate network connectivity, but this data is not retained or used for tracking.
This Application does not collect precise information about the location of your mobile device.
Since the Application does not collect any information, no data is shared with third parties.
Since the Application does not collect personal information through normal use, uninstalling it simply removes the Application from your device.
If you contact the Service Provider directly or voluntarily provide information by other means, you may request deletion of that information by contacting [email protected].
The Application is not intended for children under 13 years of age, or such higher age as required by applicable law. The Service Provider does not knowingly solicit data from children or market to them. Since the Application does not collect personal information through normal use, children's data is not at risk from use of the Application alone. If you voluntarily provide personal information through other means and are under 13 years of age, your parent or guardian must provide consent on your behalf where permitted by law.
Because the Application does not collect personal data, the risk of personal data exposure is minimal. However, no security system is completely secure. The Service Provider implements reasonable safeguards to protect systems and any data it holds.
Since the Application does not collect personal data through normal use, the risk of a data breach affecting your personal data is minimal. If a breach occurs involving any data you have voluntarily provided, the Service Provider will notify you as required by applicable law.
The Service Provider may update this Privacy Policy from time to time. The Service Provider will notify you of material changes by posting the updated Privacy Policy with an effective date. Where required by law, the Service Provider will seek your consent to material changes before they take effect.
