King of Kinks features multiple servers which you can choose to play on. The server is displayed on the bottom side of your login screen, just above the Enter button.
Keep in mind thatgame progress or purchases are not linked between servers, so make sure you remember which exact server you play on and select it accordingly.
Should you wish to change your server, you can simply click on the server button and choose from the list of available servers. By default, the game will only list the recommended servers, but you can see the full list by tapping the all button, on the bottom right of your screen.
