Limited Timed Events are short events that are only available in the game for a limited time. When an event is available, visit your clipboard in the top-right corner and select "Challenges".
To participate in a Limited Time Event, win levels to collect Coupons and then use the Coupons to clean and decorate a space! Coupons do not carry over to the next event.
If you don't have an event, the event may not be active or available to you at this time.
