I used to get the chance to watch about 10 videos from 8pm (EDT) each night for gold. It seems recently that I get ripped off a little - I watch 9 or 10 videos, but some don't give gold at the end, so I only get 6 or 7 golds . . .
I've also found that the chances to watch videos throughout the day and get one gold on "Other Offers" are just not there anymore. I tend to check every hour or so, and there are no offers (and I've learned not to do any other offers, because then my email becomes clogged with spam mail and it's not worth it.)
I've played this game for over a year and a half, and maybe it's time I say goodbye to it . . . The progress has become too slow to achieve without paying money for gold. I don't even bother playing most of the time, because I'm just trying to gain enough gold to make one upgrade, and when they cost 25+ gold, it now takes a few days to get that much. Very frustrating.
