I don't know if its a bug or if its luck, I just know that 8 to 9 times out of ten it works.
Anyway, I don't gain a lot, usually no more than 40 - 50 thousand doge per day and it takes 2 hours of gambling.
It works on two well known online altcoins casinos that for obvious reason I won't name here.
I gave my email at my first post, if you need details contact me.
