It's a familiar scenario: You download a hot game everyone's talking about. You play it so obsessively for a while that when you lie down to sleep, your brain projects the game onto your eyelids and you feel like you're playing it in your dreams. Eventually you finish the game (or hit a wall), the spell breaks and you stop playing, or even delete the app altogether.
These 11 games are addictive enough to follow that pattern. They're also clever enough to break that cycle, because the developers keep cramming in more updates, including extra modes that shake up the main game. Give 'em another try. You might find a new, old obsession.
