Fortnite Mobile is a free-to-play battle royale game where 100 players compete to be the last one standing. Players skydive onto a large island, scavenge for weapons and resources, and battle opponents while a storm circle shrinks the playable area. The core experience includes building defensive structures using gathered materials.

The touchscreen interface uses virtual joysticks for movement and on-screen buttons for actions like shooting, building, and switching items. It features the same map, seasonal content, and cosmetic items as other versions, with matches lasting approximately 20 minutes. Cross-platform play is optionally available with other systems.

Performance and visual quality are adjustable within the app to suit various device capabilities. The game is regularly updated with new themes, weapons, and limited-time modes. A stable internet connection is required to play.
