Should you raise the bet when your slot machine is on a winning streak winning almost every spin?
The only "should" that applies to slot machines is that if you play them long enough you should expect to lose money. I normally play the maximum on slot machines so I can not raise my bet. If you raise your bet you risk losing everything you have won more quickly. If you are gambling and winning money I generally would recommend not changing anything until you stop winning,
Let the stake ride. Nobody said you're a genius.
No. There is no such thing as a streak, every spin is an isolated event and doesn't change the next spin.
Previous results do not influence future results.
No you should not.
No. Only if you want to go broke.
That's why they call it a gamble. You have the same odds of winning the next time as you did the last. The odds don't change.
no hell no
