Sometimes the mobile and Facebook versions of a game will have a different number of levels.
At times, the latest levels are first released onto mobile and then adapted for Facebook, and sometimes it's the other way around. This means there can be different numbers of levels on different platforms for a particular game.
However, these will catch up when the different App Stores update their pages and include the new content. Unfortunately, this stage is out of our hands, but you won't have to wait long for everything to even out.
Some of our games focus on releasing new content exclusively for mobile devices. Just be sure to keep your mobile game app updated to access the latest levels and features. If you find yourself waiting for new levels, why not try one of our other exciting games in the meantime?
