My wife is playing with my mobile on 3 different games with 3 differents accounts.
1/ Her facebook account on Candy Crush Soda : I have to log her in on the mobile app and on the mobile website, launch the game and then reconnect my FB account on the mobile app. Like this, the game synchronize with her FB mobile app and then (when I reconnect my account) stay connected to it with the mobile website.
2/ My facebook account for Candy Crush saga : I'm connected to the FB mobile app, so no problem here, the game just synchronize with it.
3/ King account for Farm Heroes : she just have to connected to the king account on the game.
My question is : is there a way for her to synchronize the 3 games on her king account ? I'm pretty sure by manipulating the log in/out on the FB mobile app/ website, she can do it.
I know it's a little mind fucking 
THANK YOU !
