The game plays exactly how it should. It's the same as the original. Advertising thou present isn't obtrusive like in many of the apps. Just a simple 1 page advert after a game. It has social media shar buttons but i don't think I will use that feature. It also retains your high score.
This little game is simple enough to understand and great fun to play as well as challenging. It's easy to spend hours trying to get to 2048. Also, glad that it is free like the online version. Overall, it's brilliant and should definitely bring you hours of fun and frustration.
