Not sure if we're allowed to post this kind of stuff but eh...
On most occasions you can earn 10 gold free per day watching videos. You can also download games and programs or trials to earn gold.
But on several occasions I have not been paid out. I have sent Tapjoy tickets but they never pay out. I give them all the info including screen shots. But they still don't pay out and ignore my reports. They still owe me almost 300 Gold for fulfilling my side of the agreements. They refuse to fulfil their part by paying me out.
Moral of the story.... don't download anything or sign up for anything via Tapjoy. You won't get paid. I emailed them over and over again asking where my gold was. I finally emailed them and told them to KMA.
Buyer beware!
