Welcome. Suggest you play games from the MAIN MENU. There you can click on the MENU tab (upper left) and LOGOUT will appear in the drop down menu. Not saying it's the only way to do this, but might be the easiest until you get the hang things around here. To get started on the right foot, check out the Getting Started and FAQs over there----->

PS: This place can be habit forming...remember it's just a game so find time in life to do the important things first.
