Thats pure luck. You did gamble on the right time. I experienced it sometimes too. Once when I got no more idea on how to play, due to too many methods I've use which ended with no profits. I do all in my balance at 100x and to my curious, its green. I even made a mistake during my auto rolls too, setting the parameters wrongly like putting higher multiplier or wrongly set the losing event but its ended with a winning bet id. It happens sometimes tho, in a rare occasion.
