Just click on the bracket on your score history, it will show a page of the bracket. I didn't look at all of your scores, but most of what I saw were the tierless 9 hole and tierless 18 hole, those cost you nothing to enter and they pay nothing. The other one I looked at paid 1440 to the winner(which, was not you unfortunately), that one you probably paid to enter.
There is also a way to see the brackets by looking at the completed tournaments pages, but exactly how at the moment, escapes me. But if you click on the brackets in your score history, it will show you.
If I am not mistaken. All the brackets that cost you nothing to enter, pay out nothing, even to the winner. You will see when you look at the brackets, look at the Purse, it will show none.
P,S, found it, left side click tournaments, click brackets, can look at open, 3day and closed.
This is all on WGT.com, how from the PCEA/Mobile, don't have a clue.
You paid the 100 credits for the Master 18 hole bracket. Check those, in some cases I can't see beyond who entered.
