  • Steve: Hi, and welcome to our instructional video on how to win on slot machines. My name

  • is Steve Bourie, and I am the author of the "American Casino Guide," which is the number

  • one best-selling book in the U.S. on the subject of casino gambling and travel. I write a lot

  • about slot machines, and in this video I am going to explain how slot machines work, how

  • you can win on them, and I'm also going to answer some common questions that slot players

  • have, like do casinos really put the best-paying machines near the entrance?

  • Now, before we begin, let me give you some background information o5n me and why I know

  • so much about slot machines. I've been to Las Vegas to visit the facility where the

  • Nevada Gaming Control Board tests its slot machines, and I interviewed the manager of

  • that department. I've also been to Atlantic City where I visited the facility that tests

  • slot machines for the New Jersey Casino Control Commission, and I interviewed the Director

  • of its Division of Gaming Enforcement.

  • Actually, I wrote a story about my visit to those two places, and you can read it on my

  • website at AmericanCasinoGuide.com, or just go to Google and type in the phrase, "Are

  • slot machines honest?" and I'm sure you'll see it pop up as number one or two in the

  • search results.

  • I've also visited the headquarters of Gaming Labs International, which is the world's largest

  • independent laboratory for testing electronic gaming machines, and I interviewed its Director

  • of Operations about the company's procedures.

  • I've also gone to Reno, Nevada, where I took a private tour of the headquarters of International

  • Gaming Technology, which is the world's largest manufacturer of slot machines. Plus, while

  • I was there, I interviewed the company's Chief Software Engineer.

  • Finally, I've interviewed slot managers at major casinos in Las Vegas, Reno, Atlantic

  • City, and elsewhere in the U.S. about how they decide about which machines to put on

  • their floor and what kind of payout percentages those machines should have.

  • So, are you all ready to get started?

  • Good, let's begin. The first thing we need to talk about is how slot machines work. Every

  • machine has a computer chip inside it called a random number generator, or RNG, and that

  • chip is making mathematical calculations very quickly, about 1,000 times a second, to determine

  • which combination of symbols should appear in the reels.

  • Then, when you push the spin button or pull the handle, that causes the chip to stop at

  • that exact instant and choose a combination to display on the reels. This means when you

  • see the reels spinning, the actual result of what will appear on those pay lines has

  • already been chosen by the RNG.

  • So, in reality, a slot machine wouldn't even need the spinning reels to show you whether

  • you won or lost, but it's certainly a lot more exciting to see those spinning reels.

  • When a casino orders a slot machine, the manufacturer will have a choice of computer chips to put

  • into the machine which control the percentage of how much that machine is set to pay back

  • to the public. The range of the payouts on these chips will vary depending on the machine

  • and the manufacturer. But it's usually pretty standard in the industry to offer chips paying

  • out from a low of about 85% to a high of about 98%.

  • So, how do the casinos decide which machines should pay back around 85% and which ones

  • should pay back around 98%? The answer is that it is done by denomination. The higher

  • the denomination of the machine, the more it's set to pay back. If you play a penny

  • machine, you can be pretty sure that it's set on the low end of the scale to pay back

  • around 87% to 90%. And if you play a $25 machine, the payback on that machine is going to be

  • on the high end around 95% to 98%.

  • If you want proof of this, all you need to do is look at the public record of each state's

  • gaming statistics. We check with gaming regulators in every state each year to find out what

  • the machines actually paid back to the public, and we post all of that information on our

  • website. Just go to AmericanCasinoGuide.com and click on the link that says "Slot Payback

  • Info." That will bring up a list of states, and you can just click on the state that you

  • are interested in to see what the machines pay.

  • For Nevada, you can also get information on a particular city, and if you look at Las

  • Vegas, you can see that the penny slots returned around 88% while the $25 slots returned around

  • 96%.

  • Okay. So now you know how a slot machine works and you know how casinos decide what they

  • should pay back to the public. But the big question is, "How do you win on a slot machine?"

  • Well, the answer to that is very simple. You get lucky.

  • Keep in mind that the slot machine is basically just a computer that is programmed to randomly

  • pay out less money than it takes in. And unlike video poker where there is a skill involved

  • in how you play your cards, there's no skill involved with a slot machine. It's all luck.

  • Therefore, when you play a slot machine, you are hoping that you can get lucky and stop

  • that random number generator on a winning combination.

  • So, if you ever see an ad for someone selling a system to beat slot machines, don't believe

  • it. There is no system for winning on slot machines, and if there was a winning system,

  • don't you think someone would keep that information to themself rather than sell it to you for

  • $10 or $15.

  • Now let's address some common questions that people have about slot machines.

  • Question: Are slot machines set to pay out at set intervals or once they've collected

  • a certain amount of money?

  • Steve: No. The outcome of each play on the machine is completely random. There is no

  • predetermined point at which a machine is set to pay out.

  • Question: If a $1 slot has a chip inside that is set to pay back at a rate of 93%, does

  • this mean that if I put $100 through that machine, I'll have $93 left when I'm done?

  • Steve: No. The 93% is a long-term number and actually represents the results after several

  • million pulls on that machine. Some days the casino will lose money on that machine. But

  • on most days, it will make money, and the longer the machine is played, the more likely

  • the result will be that the machine will have an average payout of 93%.

  • Question: If I play a slot machine and it's not paying out, does that mean it's due to

  • hit soon?

  • Steve: No. Every play on a slot machine is an independent event, which means that its

  • past performance can't be used to determine its future performance.

  • Question: If I play a slot machine and win a jackpot, will that machine stop paying out

  • to make up for the jackpot I won?

  • Steve: No. Every time you play a slot machine, the odds remain constant as to whether or

  • not you'll win. If the odds were 20,000:1 for you to win a jackpot and you were lucky

  • enough to win it, the odds will still be 20,000:1 for you to win another jackpot on the very

  • next spin.

  • Question: Do casinos change the payback percentages on a slot machine at the flip of a switch,

  • or can they loosen machines during the week and then tighten them up on the weekend?

  • Steve: No. Once the payback percentage chips are set by the casino, they are rarely changed.

  • In order to change the payback percentage, a casino technician would have to physically

  • go into each machine and replace the chip. This is an expensive and time-consuming process,

  • so it's rarely done.

  • Now, I need to mention that there is a new technology called server-based gaming where

  • the payback percentage could be changed by the flip of a switch on a central computer,

  • but it's very new, it's very expensive, and only a handful of casinos have it and only

  • on some of their machines. Also, the gaming regulations for these machines would not allow

  • any changes to be made while someone was actively playing a game.

  • Question: Do slot manufacturers purposely program a near-miss feature into their slots

  • to make it seem like you almost won a jackpot?

  • Steve: Well, before I answer that, let me first explain what a near-miss is on a slot

  • machine. That would occur when the random number generator knows that the player's spin

  • will be a loser, and the machine is then programmed to show you two winning combinations directly

  • on the payline, with the third combination appearing just above or below the payline.

  • This would make you think you almost won and possibly encourage you to play more on that

  • machine. Actually, there was a story on this subject many years ago on the ABC News program

  • 20/20. I wrote about, and as I mentioned before, you can read that story on my website or just

  • go to Google and type in the phrase, "Are slot machines honest?" and you'll see it pop

  • up in the search results.

  • But the answer to this question is no. Nevada Gaming Regulations do not allow a manufacturer

  • to purposely program a near-miss feature into a slot machine, and any manufacturer licensed

  • in Nevada would not be able to do that in any other state.

  • Question: Suppose I play a machine for 30 minutes, and as I'm leaving, someone sits

  • at my machine and they hit a jackpot. Would I have won that jackpot if I had stayed at

  • that machine?

  • Steve: No. The random number generator is cycling through various combinations at about

  • 1,000 times a second. In order for you to have won that same jackpot, you would have

  • had to push that button at the exact same microsecond that the other person did, and

  • it would be virtually impossible for that to happen.

  • Question: Do casinos really put "looser" machines by the entrance doors or on the aisles?

  • Steve: No. Like I said before, the payback percentages on slot machines are fairly constant

  • within a particular denomination. This means you won't find some penny machines set at

  • an 89% payback in one area of the casino and 98% in another area. They are all set to pay

  • back within about a 1% range of each other.

  • Question: When I get to a bonus round on a video slot and I have to choose from various

  • symbols to determine my bonus, does it really matter which symbols I choose, or is it all

  • predetermined?

  • Steve: Yes. It really matters which bonus round symbols you choose. The machine does

  • not predetermine the outcome, and it's up to you to keep choosing winning symbols until

  • you pick the losing symbol that ends your bonus round.

  • So, there you have it. Hopefully, I've answered most of your questions about slot machines

  • and you'll be a little more knowledgeable the next time you sit down to play your favorite

  • machine. Don't forget that you can get more information on slot machines as well as all

  • other casino games on our website at AmericanCasinoGuide.com.

  • Also, if you have any questions, you can post them on the discussion forum on our website,

  • and I'll be glad to answer them for you. Thanks for watching, and best wishes for good luck

  • on your next visit to the casino. http://www.americancasinoguide.com/
