Yes, they show up one at a time (red screen). No idea on max number of spins - depends on a lot of factors, like the machine you are playing and how many potential bingo patterns are available to hit.
If every spin is completely independent, back up spins make no sense. Back up spins would imply there is a greater likelyhood of hitting a feature after having already hit a feature. Despite the fact that it definitely seems this way, it's completely random and there are zero patterns to infer. There are a lot of features of slot machines that go unexplained, but we wont worry about that. To summarize: Humans make flawless software with no chance there could ever be any way to exploit it. Perfect unwxploitable software.. These slot guys should get into cyber security.
They dont imply that your odds are any different on backup spins. Its more if you hit something decent, take the chance and see if you can hit a bit more. For a huge win, it more of a courtesy move to clear the win off before leaving the machine. So people dont see the big hit and think erroneously that they have no chance at hitting it and play another machine. You definitely dont have to do it, just more fun that anything since you have won some. There may be the rare property that will actually ask you to do it so that it clears the win for the above reasons.
I don’t think the idea is that there’s a greater likelihood of another win, but a second win in a row might increase your win exponentially and given that it’s generally being wagered with ‘winnings’ it’s a low risk high reward gamble.
Yeah, we're not going to increase our bets like so many other RU-vidr's do. We stick to our guns and only risk higher bets if we are doing well or choose to limit our # of spins.
Never understand why people want to see ultra high gambling. If it is streamers online they are almost certainly playing with casino money and if it is live, and they are not getting significant kickbacks from casinos, then they are still playing with “dream” money for most of us which I, for one, cannot relate to in the slightest.
