For most of it, they've taken away that opportunity. I think there's an announcement somewhere about people 'abusing the system' but using 2-3 devices or something to get as many 'free' credits as possible then buying equipment.
So I'm as the others mentioned. I can rarely watched any more then 1 or 2 videos if lucky. Or sometimes none as you get to a level where you are restricted to watching them.
Now it will take me weeks just to get to 100 gold coins to buy a decent ball let alone anything else.
A little disappointing. I guess they want us to spend real money. Forgot it.
