Account settings and cities > Nominate a Deputy

Sometimes you may not have enough time to play the game and need another player (deputy) to have limited or full access to your game.To do this go to account "setting" as you see in the image below and enter the name of deputy in the "deputy page" and choose the level of access.

And go to "deputy" section

You can have two deputies the same time and if you want to remove or replace deputy you can follow the same process.
