Using emulators (such as Bluestacks) is currently not against our Terms of Service, so you won’t get banned for using them. However, we cannot officially support them, so we recommend to not use one.

We can only offer support for Android and iOS device platforms.

Please note, while it is not forbidden to have multiple accounts, we also cannot offer official support for multiple accounts as the game is designed to be played with only one account per person. 

Game Center and Google Play only support one game per account. Trying to save multiple games to same account will result in lost data.
