throw dice problem

RiadDahoe

so i played the " throw dice" for the first time. i played the 13 times, won 8 and lost 5 . But i went from 115 gold to 50 gold, so even on my wins , it deducted 5 gold everytime.

Same problem here. I bet 5 times, won 1 of 5, lost 3 of 5 and won 1 of 20. Not gold recieved.
I read the answer in other posts. Apparently you get the reward in coupons. Meaning it's a crappy feature, with fake explanation. Since you spend money to get the gold they should clarely say that the reward would be given in coupons so that we know where are we spendig our money in.
