Whether or not there's any chance of actually earning enough credits or "cash" to cash out on anything, you'll spend litterally three times more time waiting for ads to play out than you will actually scratching tickets. The same 4 or 5 ads. Over. And over. And over. And over again. After months of playing I've made it 1/3 of the way to a $2 gift card. If you spend half the time searching the couch cushions or looking under vending machines, you'll find more money, and still retain more dignity.
