I dont know, maybe it's just my guesses, but yesterday I had 150 losses in a row, the game crashed before reaching my profit and would have reach at 151 time, but my balance had already ended at that time. Now Ive edited the strategy and in the morning (+5 GMT here) I have found out that some player is following me, though after some time he disappeared. I think that if two or more people earn according to one effective strategy, then most likely this will be monitored and the chance to earn decreases, although this is my guess.
With a >0% house edge there is no strategy that will guarantee that you will win, and it doesn't matter if there's another player trying to cash out just before the game busts as the bonus system has been removed if this is what you had in mind.
