In-game Events are limited-time events where players complete Event Challenges for rewards. To unlock the rewards, you'll need to complete Event Challenges. Each Event Challenge you complete will grant a specific Event Item. Event Items are claimed from the Challenges Menu.
The next in-game event is Llama-Rama. The event started on March 25, 2021, and ends on April 9, 2021.
