Differences between Warzone.com and the mobile app
Accounts share full party between the website and the app. That is, if you create an account with any device or computer, you can sign into that account on any other device or computer.
 Multi-Player Games
Multi-player games share full party between the website and the app. If you create or join a game using any device or computer, you can always play that game from any other device or computer.
 Single-Player Games
If you beat a level while signed into your account, your score will be saved and the next level will be unlocked across all devices and computers. However, if you save an in-progress single-player game, that game can only be continued on the same device or computer.
In order to join, leave, or view the status of a ladder, you must view the Warzone website. If you are using the Warzone app, you must open your browser and visit the website to join or leave a ladder. However, like tournaments, once you join a ladder, the ladder games will appear on your My Games page just like any other games, so you can play them from the Warzone app.
 Map Creation
If you want to create your own maps, you must do this via the website from a computer. Maps cannot be created on mobile devices since it requires the Flash plugin.
