A usual experience indeed. I also experienced that whooping x1000 drop on Sweet Bonanza 1000, not just once, not just twice, but 3 times already. The winning pattern only cost a few bucks but since there's a x1000, the reward became great. And it happened 2 more times later on with a much higher bet.
The feeling is damn so happy, and that's when I started to become hooked on that game. Several game sessions have passed, and still getting a good win on that game even without huge multipliers. Until I slowly realized that my luck there was fading, but still, I decided to see my luck rate.
The end result is.... You know it already.

Those 1000x extraordinary hits on Sweet Bonanza just illuminate your brain, but you know those designs, bells, lights, and intermittent giant wins on the slot machine will never ever let you relax. As you mentioned, "
the end result" is pulling you in deeper even as luck turns pale. Until you limit your sessions and count your winning as banked profit, there is no need to be tense. Otherwise, that zone effect could leave you chasing the high long after it's gone. I always set my daily loss cap, if my balance hits the loss cap, I pause immediately, it really helps me to keep both money and fun alive. Actually, I can't deny it is really hard to pause immediately every time, so I diversify my leisure with many things, not only gambling, I just switch to another one.
