In Chinese language, the 8 is good luck. That's why the machines are 888 or $8.88. The more you notice it, the more you see how Vegas caters toward the Chinese. I've only seen 2 Japanese games, a few Spanish games. Many Chinese games on the floor.
The worst are the annoying button pushers during a bonus. They keep slamming the button. Be cool and make like you've hit a bonus round before. They have IG pages dedicated to vids of people doing this thinking it will help them win. Or hitting the spot on the screen, etc...
Slot machines are pure timing. if it hits while you are playing, it just means you were fortunate to have been at that machine at that moment.
There's a computer geek from CA who went to Vegas i think about one weekend each month. He didn't gamble big, just enough for the thrill. Mostly there to party and hang with his friends. Anyway, he had a few tokens (this was before tickets) that he forgot to cash in, so he put his last 3 in a Megabucks on his way out of the casino (I want to say Caesar's). Anyway, it hit the jackpot, and he left Vegas that particular time a multi-millionaire.
Pure timing.
I've seen people refuse to leave a machine they'd been feeding for hours, because they just know it's about to pay out, and they don't want the next person to take all their winnings (more like losses).
In Japan, the military clubs and Rec Centers have slots to pay for MWR programs. I've won hundreds (sometimes thousands) each time I played, because the machines are set very loose -- they give back like 98% of everything people put into the machines. I learned what times the machines tend to hit jackpots, so I tried to play only at those times. i paid for my lunch almost everyday with a brief stop at a well-selected machine.
I watched a guy in Atsugi who was in the clubs every single day. I only went a few times a week, but he was either at the place or had just left to go to another club every time I went. Not sure if he even had a job, or maybe they didn't miss him being gone. He went from club to Rec Center and back for hours trying to hit the jackpots. He stayed on a machine for hours if needed, because those did eventually pay. One night he was bragging he was up $5K after 8 hours of play. i can't imagine that was normal, or he wouldn't have been bragging.
The machines that paid best had 3 jackpot levels, depending on the color of the 3 sevens and which line they were on. I think 3 blue sevens on the bottom of 3 lines line was the best.
One Sunday, the day before I was to leave for home, I went to the Rec Center for breakfast. There was that guy on the same machine I saw him on the night before! He'd been playing it all night trying to get his money back. By then he'd put in over $2K, and the top jackpot was $2,500 -- so he was close to being down even if he hit.
He was so mad! Every time he spun the reels, he was lucky to get half his bet back -- not even enough payout to keep him afloat for a few minutes of play without feeding it again, and again, and again. most spins came up empty -- not even a cherry was hitting!
That was about 9:30am. I finished eating, played a few machines and hit 2 jackpots totaling $2400. That guy was just giving me the evil eye, like I was taking all his luck. Those machines paid out actual quarters, and as a jackpot was paying, you had to get the worker to refill the hopper until it was all counted out. Then you took the plastic cups full of the same quarters to the cashier window to cash out. It's how Vegas used to be before tokens and paper tickets.
Finally, about 3:00, the guy had enough and decided to leave. Dinner had just started being served, so i decided to eat again. When i left, i had to walk right past that machine. Well, almost past. I stopped and put $40 in, and I hit the top jackpot!

The whole time I was waiting for that slow-ass machine to spit out $2,500 in quarters with the worker opening and refilling it several times, the people in line for dinner -- some of whom had also seen that guy the night before -- were saying, "Man, he's gonna be pissed when he finds out!"

I was looking over my shoulder, half expecting to see him walk in and "catch" me!
I decided to avoid the Rec Center, so i stayed in my room until my bus to the airport left.
