Coin earning

This app is awesome but the coin earning is a little weird I have completed a couple of the tapjoy app coin offers but when I complete them it doesn’t give me the coins like the final fantasy one and I spent all that time trying to earn the coins and I didn’t get them also the solitaire please tell me what I’m doing wrong
