"Embark on an unforgettable social adventure and an ever-expanding world. Sky: Children of the Light is a heartwarming and beautifully animated social adventure experience designed to be played together by you and your loved ones. Set in a wonderland above the clouds, Sky invites you and your friends to fly up to explore the buried mysteries together and rebuild a fallen kingdom for its ancient inhabitants. Using your courage and compassion, players must connect as a community to share and build on their flame to spread light back into the world. "

In Sky, players explore a once prosperous kingdom using a cape that gives them the ability to fly. The in-game world consists of seven unique realms, each with a different theme being represented as a stage of life and a variety of areas to explore. There is also Home, a small island which serves as the world hub and the starting place when the game is opened. Throughout the world, players encounter "spirits" that allow them to unlock items in return for in-game currency, and "children of light" that give players "winged light". When a player has collected enough winged light, their cape level goes up, increasing the cape's maximum energy and allowing the player to fly farther.
