I had something very strange just happen to me on betfury. You guys know the spinning wheel right, under the bonus tab.
In my spin the arrow clearly, and I mean CLEARLY!!, landed on 1 eth, I already thought "OMG" and then I got 5000 BTTC, the reward for the field before ETH.
Too bad there is no way to prove that since you cannot see the spin again or even the result because the window changes after the spin.  Never though these spins with 99% 0.01$ rewards would trigger some frustration in me.
