I ran it nearly 2 weeks and wasn't getting anything either. I mean, the loot itself is a bit trash, even when you win. But I finally said, "You know what? It's been at least a minimum of 50 runs already. So I stacked those chips, and I wagered all of it. I won that first run of the max wager, I not only got a near or flawless run but was able to finish the emblem, get the title, and the stone dropped all at once. So I dont know, but save your chips, you can try to do max wager 3 or 4 times in a row. I had about 14 from all the time I was grinding
