A. Your User ID# can be found in the options menu. Just open the menu and you will see the number at the top of the pop-up (see the picture below).
If you need to send our support team your User ID# you can take a screenshot of your screen and send the picture along with your message. If you use the support button inside the game (also found in the settings menu) then your User ID# will be automatically added to your message.
If for some reason you can't get either of these options to work then please make sure you write your User ID# in your message to us. Otherwise it will be hard for us to help you if you are having a problem in the game.
