The Arcade tab is where you can discover new games every day! It has a number of headings:
Whenever you tap the Favorite button on a game, it appears here. It's a convenient way to bookmark games you like and want to play again. Even works offline!
An automatic list of games other users are currently playing and liking. (The exact ranking algorithm is a work in progress.)
List all games with a specific tag. But the most important button is New, where you'll see every game and every update, listed newest first.
Whenever you click a game link, in search or as shared on social media, the game box will appear here.
