Personally, the most I have seen is only seven, but again, I haven't played it much. I'm curious to hear different people's experiences with this and would appreciate the feedback!
Cheers!
I also don't play much on Crash game at Roobet. But it's fun to see how gamblers decide where they should stop. There's lots there that is just stopping in a very beginning, I think it is to avoid large loss, and to to win small amount. Upon watching and playing some there, I've seen about 6 or 8 reds.
