You may be offered the option to watch ad videos from the Bonus Window in return for free Coins. If you are running into any trouble, we recommend taking the following steps:
  1. Check your Internet connection. The feature requires you to be connected to a strong Internet connection for the videos to be available. Try refreshing your Internet connection, or switching to WiFi.
  2. Restart your device and make sure no apps are running in the background.
  3. Take breaks between videos.
For best performance, we recommend a 10-15 second break between each video, to make sure each reward has time to be collected.
