There are two ways to report bugs or send suggestions to us.
1. Open the app on your device and access the “About” menu. Now choose Feedback, fill in the form and send it to us via email. This option is easier, if you want to attach screenshots. It also often offers to automatically attach technical information about your device.
2. Contact by opening a Support Ticket here. Do not forget to mention the game title and the device you're experiencing problems on.
