The Weekend Event runs on Saturdays and Sundays.
You need to complete various game tasks. There can be a maximum of three tasks available at a time.
When a task is completed, you will receive the next one.
A task can be replaced once per day for free, and afterwards you can replace it for rubies or by watching ads.
There may be an occasional timeout for receiving tasks, which you can skip for rubies or by watching ads.
You will get a prize and reward tokens for each completed task.
Additionally, there are rewards for completing weekend event stages. To receive these rewards, you need to accumulate a sufficient amount of reward tokens.
The event icon can be found in the Right Menu on the Main Screen.
