Since Hidden Chronicles hasn't reached a point where Zynga feels Estate Cash needs to constantly be on sale, it's a safe bet that you'd probably like to have all of the free Estate Cash that you possibly can. Since this is only worth a single Estate Cash, your input is incredibly limited, and comes in the form of simply watching a commercial about the product. At the end of the video, you'll be awarded your free Estate Cash, but don't be surprised if you have to wait a few minutes or even refresh your game before Hidden Chronicles actually confirms that you've earned it.

While this promotion might be a disappointment in the long run, as a single Estate Cash won't buy you... well, much of anything, if you save it up with the Estate Cash you earn by simply playing the game, perhaps you will eventually be able to buy yourself something nice.
