The Dashboard is the first thing you see after logging in, and it works as your home base. It's where your streak, level, and XP live, so you can always see your progress at a glance without digging through menus.
From the Dashboard, the fastest ways to jump into the action are the quick links to Play Games, the Mall, and Movies. If you're looking for something more specific — your Profile, Weekly Missions, or your current Rank — those are also reachable directly from here.
Anytime you land on a page for the first time, you'll likely see a short welcome popup explaining what that section is for. These are one-time tips, so don't worry if you don't see them again after the first visit.
