Differences between Warzone.com and the mobile app
Warzone can be played both on the website and via an iOS/Android app. The primary game is the same between the two, however, there are some differences. This page explains the differences.
Accounts
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.
