I found a serious flaw after playing at this site using the auto roll feature. Not accusing of any shady tactics, but...
My auto-roll settings is a martingale progression (x2) after each losing bet, and all bets alternate (high to low, low to high bet)
After a streak of 20 losses, it will go back to the base bet and start over.
You can fully see those two base bets suddenly in there, which win, however the site keeps going up on the next losing bet.
The auto-roll then resets back to the base bet, even though there was no 'streak' of 20 losing bets as there was suddenly those two winning bets, which were coincidentally the small base bet.
This is just a small loss, but what if the bet sizes were larger? I would avoid this site until this issue is resolved. I have kept the server hash, server seed, and client seed.
