Update:
I dont think it pays out correctly. I use terrawallet.com and I havent received any coins back yet.
Well, it is our pleasure

Now, as for your not getting coins back, I'm not familiar with terrawallet.com but remember that the system pays to the address of the first input in the transaction. This means that if you are using an online wallet chances are they send coins from their pool of addresses and you lost your payment to them.
This is very important and is stated on the site and on the original post for DoC: You must have control over the address(es) from which the coins are sent, because that's where your earnings will be sent to!
Do get in touch with me by PM about this and we'll work something up for the wager you already placed, but don't place any other from an online wallet, that will NOT work.
Thanks for the info. I did not know that. Dont worry about the coins, it was only 20.
