How Do Slot Machines Work At Casinos

admin

The gaming industry is big business in the U.S., contributing an estimated US$240 billion to the economy each year, while generating $38 billion in tax revenues and supporting 17 million jobs.

What people may not realize is that slot machines, video poker machines and other electronic gaming devices make up the bulk of all that economic activity. At casinos in Iowa and South Dakota, for example, such devices have contributed up to 89 percent of annual gaming revenue.

Spinning-reel slots in particular are profit juggernauts for most casinos, outperforming table games like blackjack, video poker machines and other forms of gambling.

Let’s assume you want to play the slots. A good ballpark estimate for the house edge on a slot machine game is 6%, but who knows? (The casino does, but you don’t.) To wager $3000 35 times means you must put $105,000 into action. The expected loss on that much action is 6% multiplied by $105,000, which is $6300. Casinos that operate Class II slot machines insist that they offer similar odds to Class III machines. The analogy they use is of a scratch-off lottery ticket–instead of scratching off a card you’re pulling a slot machine handle to determine if you ‘win a prize‘. Although there’s likely a lot of truth to this concept most serious. Here is the best casino website where I used to play always.

What about slot machines makes them such reliable money makers? In part, it has something to do with casinos’ ability to hide their true price from even the savviest of gamblers.

The price of a slot

An important economic theory holds that when the price of something goes up, demand for it tends to fall.

But that depends on price transparency, which exists for most of the day-to-day purchases we make. That is, other than visits to the doctor’s office and possibly the auto mechanic, we know the price of most products and services before we decide to pay for them.

Slots may be even worse than the doctor’s office, in that most of us will never know the true price of our wagers. Which means the law of supply and demand breaks down.

Casino operators usually think of price in terms of what is known as the average or expected house advantage on each bet placed by players. Basically, it’s the long-term edge that is built into the game. For an individual player, his or her limited interaction with the game will result in a “price” that looks a lot different.

For example, consider a game with a 10 percent house advantage – which is fairly typical. This means that over the long run, the game will return 10 percent of all wagers it accepts to the casino that owns it. So if it accepts $1 million in wagers over 2 million spins, it would be expected to pay out $900,000, resulting in a casino gain of $100,000. Thus from the management’s perspective, the “price” it charges is the 10 percent it expects to collect from gamblers over time.

Individual players, however, will likely define price as the cost of the spin. For example, if a player bets $1, spins the reels and receives no payout, that’ll be the price – not 10 cents.

So who is correct? Both, in a way. While the game has certainly collected $1 from the player, management knows that eventually 90 cents of that will be dispensed to other players.

A player could never know this, however, given he will only be playing for an hour or two, during which he may hope a large payout will make up for his many losses and then some. And at this rate of play it could take years of playing a single slot machine for the casino’s long-term advantage to become evident.

Short-term vs. long-term

How do slot machines work at casinos games

This difference in price perspective is rooted in the gap between the short-term view of the players and the long-term view of management. This is one of the lessons I’ve learned in my more than three decades in the gambling industry analyzing the performance of casino games and as a researcher studying them.

Let’s consider George, who just got his paycheck and heads to the casino with $80 to spend over an hour on a Tuesday night. There are basically three outcomes: He loses everything, hits a considerable jackpot and wins big, or makes or loses a little but manages to walk away before the odds turn decidedly against him.

Of course, the first outcome is far more common than the other two – it has to be for the casino to maintain its house advantage. The funds to pay big jackpots come from frequent losers (who get wiped out). Without all these losers, there can be no big winners – which is why so many people play in the first place.

Specifically, the sum of all the individual losses is used to fund the big jackpots. Therefore, to provide enticing jackpots, many players must lose all of their Tuesday night bankroll.

What is less obvious to many is that the long-term experience rarely occurs at the player level. That is, players rarely lose their $80 in a uniform manner (that is, a rate of 10 percent per spin). If this were the typical slot experience, it would be predictably disappointing. But it would make it very easy for a player to identify the price he’s paying.

Raising the price

Ultimately, the casino is selling excitement, which is comprised of hope and variance. Even though a slot may have a modest house advantage from management’s perspective, such as 4 percent, it can and often does win all of George’s Tuesday night bankroll in short order.

This is primarily due to the variance in the slot machine’s pay table – which lists all the winning symbol combinations and the number of credits awarded for each one. While the pay table is visible to the player, the probability of producing each winning symbol combination remains hidden. Of course, these probabilities are a critical determinant of the house advantage – that is, the long-term price of the wager.

This rare ability to hide the price of a good or service offers an opportunity for casino management to raise the price without notifying the players – if they can get away with it.

Casino managers are under tremendous pressure to maximize their all-important slot revenue, but they do not want to kill the golden goose by raising the “price” too much. If players are able to detect these concealed price increases simply by playing the games, then they may choose to play at another casino.

This terrifies casino operators, as it is difficult and expensive to recover from perceptions of a high-priced slot product.

Getting away with it

Consequently, many operators resist increasing the house advantages of their slot machines, believing that players can detect these price shocks.

Our new research, however, has found that increases in the casino advantage have produced significant gains in revenue with no signs of detection even by savvy players. In multiple comparisons of two otherwise identical reel games, the high-priced games produced significantly greater revenue for the casino. These findings were confirmed in a second study.

Further analysis revealed no evidence of play migration from the high-priced games, despite the fact their low-priced counterparts were located a mere 3 feet away.

Importantly, these results occurred in spite of the egregious economic disincentive to play the high-priced games. That is, the visible pay tables were identical on both the high- and low-priced games, within each of the two-game pairings. The only difference was the concealed probabilities of each payout.

Armed with this knowledge, management may be more willing to increase prices. And for price-sensitive gamblers, reel slot machines may become something to avoid.

The word “comp” is short for “complimentary.” In the gambling industry, comps are free stuff you get from casinos and other gambling companies to incentivize you to gamble with them. Generally, you get more comps based on how much you’re gambling.

When discussing comps, it helps to understand the expression “action.” Being “in action” just means that you have money riding on a bet of any kind.

But “action” also refers to the amount of money you have wagered. It can refer to the amount of money you wager over a period of time, too.

For example, if you’re playing slot machines and betting $1 every time you spin the reels, you’re putting $1 into action every time you spin. If you make 600 spins per hour, then you’ve put $600/hour into action.

Based on the odds behind the game and the payout odds, casinos can estimate the long-term expected losses based on your hourly action. They can then calculate a percentage of that to return to you in the form of comps.

When you’re dealing with traditional land casinos, if you bring much action to the casino at all, you’ll be assigned a casino host. This is the person at the casino responsible for keeping you happy so that you don’t take your action elsewhere. Comps are the main tool a host uses to keep you happy.

Of course, not everyone has a host. You can also get comps almost automatically by signing up for the players’ club and inserting the card into the machines as you play. Pit bosses also have the authority to reward you with comps when you’re playing table games. In fact, the simplest and most common type of comp is the free drink. As long as you look like you’re playing a slot machine, a cocktail waitress will bring you free drinks all night. (She’ll be more attentive if you tip her well, though.)

This post explains the different kinds of gambling comps and what they mean to you as a gambler.

The Different Kinds of Comps Available

Comps are awarded in a hierarchy based on your value to the casino. The most basic comp is the free drink. Casinos have multiple motivations for gving you free drinks.

For one thing, a gambler who’s inebriated has lower inhibitions. He’s more likely to gamble more money longer. And the #1 factor affecting how much profit a casino makes from a gambler is the amount of time he spends playing.

That’s because casino games have an innate mathematical edge. This edge doesn’t have a huge effect in the short term, because in the short term, anything can happen. But the law of large numbers suggests that the more bets you make, the closer your actual results become to the theoretical results.

Here’s an example:

The mathematical expectation at blackjack is for you to lose roughly 1% of each bet you make on average over time. (This assumes you’re using basic strategy while you play.) That means the casino expects you to lose an average of $1 every time you place a $100 bet.

In the short run, that’s impossible. If you place a single bet at blackjack—which is the ultimate example of the short term—it’s impossible to lose $1 on a single $100 bet. You’ll lose $100, win $100, or win $150 most of the time. If you double down or split, you might win more–$200, $300, or even $400 wins are possible. You might also face a “push,” which is a tie. Your bet is returned, but you don’t win any money… that’s a loss or win of $0.

None of those outcomes come even close to a loss of $1.

That $1 loss is an average over time–over a huge number of bets. If you make 10,000 bets at $100 each, you’re likely to lose close to $10,000. Even with that many bets, it’s possible to deviate wildly from the mathematical expectation.

If you’re the casino, you want to get into the large number range as soon and as often as possible. This ensures your profit. The way to do this is to get players to make lots of bets for lots of money.

And providing free alcohol helps with that. In fact, it’s a small price to pay for the extra action they see.

You can expect more than just free drinks, though. Free food is a small step up from free drinks. At a casino of any respectable size, you’ll find multiple restaurants on site. The 2nd most common type of comp is free food at one of the on-site restaurants.

The free food comp is usually awarded in the form of a coupon. You might have to put more money into action than you think to be awarded free food, but it sometimes depends on the generosity of the pit boss. It can also depend on what kind of rapport you have with the casino staff.

I once got into a spirited conversation with the cardroom manager at Planet Hollywood Casino in Las Vegas. They had a hot dog joint there called Pinks—I guess it’s popular on the West Coast. Anyway, I was trying to convince the cardroom manager that he should buy everyone at the table hot dogs.

Apparently, at the limits I play, you don’t get free hot dogs.

If you qualify for free food and free drinks, you’re not far from qualifying for free lodging, too. Most casinos are also hotels, but even casinos which don’t have attached hotels will get you lodging nearby—if you’re gambling enough.

You can also get upgraded to a nicer room by virtue of the action you bring the casino. (You might also be able to get upgraded to a suite or a nicer room by tipping the desk person $20 when you check in, but that’s not really related to comps.)

How Do Slot Machines Work At Casinos Online

In fact, these 3 comps—room, food, and beverage—are so common that they have an abbreviation for it. Bettors who qualify for all 3 are called “RFB” customers.

Notice something about all these comps, too. You’re getting comps that seem to have a certain value. A drink is probably $5 at the bar at a casino. A meal is usually $15 or $20. A room can vary wildly in price, but is often at least $50, $100, or more.

But those are the retail prices for these comps. The casino doesn’t pay $5 when they mix you a drink. Their cost for that shot of Crown on the rocks is probably closer to $1. The meal at the buffet that the public pays $15 for probably only cost the restaurant $5 to make.

And a hotel room that’s sitting empty generates no money for the casino at all, so they might as well give it away. In fact, the Winstar in Oklahoma has such low occupancy rates during the week that almost anybody can get a comped room. You don’t have to bring them much action at all, really.

Those are just the standard comps for regular down-to-earth players like you and me. High rollers, or “whales,” as the industry calls them, are eligible for all kinds of free stuff. Many of these comps are customized based on what the host knows about the gambler’s interests.

It’s not unusual for a casino to pay for airfare and transportation to and from the airport for a big player. In fact, that’s expected for any high roller.

But entertainment is another popular comp. If you like golf, shows, or sporting events, you can usually get a “free” ride from the casino to go to those outings, too.

Rebates are common, too, even if you’re not a high roller. For low rollers, rebates are often awarded in the form of coupons or free play. High rollers can receive cash or a check as part of their rebate.

The comps program is part of the casino’s marketing plan. Most casinos make heavy use of direct mail to entice gamblers to return to their casino and play. If you’re a member of the players’ club at the casino, you’ll inevitably receive standard comps in the mail.

Based on your interests and betting tendencies, you’ll also get free offers for other perks in the mail, too.

Even low rollers can get free transport to and from the casino. I see buses taking groups of gamblers to the Winstar all the time. Many of the people riding those buses pay nothing for the ride, although they lose enough money at the casino to more than make up for that cost.

But calling these comps “free” is inaccurate. You pay for these comps in the form of gambling losses, even when you’re winning.

How Gambling Companies Do the Math That Makes Their Comps Program Profitable

Other than the free drinks and occasional free coupons sent in the mail, most casinos award comps based on your actual time spent playing. They account for how many bets per hour you make and at what amount when deciding how much to award you and when.

But comps aren’t based on how much you actually lose. Instead, casinos calculate your comps based on your theoretical expected loss. This is a function of the house edge for the games you’re playing, the time you spend playing, and how many bets per hour you’re making.

Over the long run—and casinos serve thousands of customers per day—the casino has an excellent idea of how much your play is worth. If you’re on a winning streak, you still get comps based on your action. The calculations are based on your expected losses, not your actual losses.

Here’s how the casino calculates this:

You play slots exclusively, but you bet $3 per spin. You’re an average player, so you’re making 600 spins per hour. That’s $1800 per hour you’re putting into action.

If the casino knows you like the machines with a 95% payback percentage, they figure that in the long run they’re going to make 5% of your hourly action—or $90 per hour. (5% of $1800 is $90.)

If you spend an average of 4 hours a day playing slots, the casino assumes you’re going to lose $360 a day while you’re there.

They then award you comps based on a percentage of that $360 per day.

How Can You Best Take Advantage of the Casinos’ Comps Programs?

If you’ve heard of the books The Frugal Gambler by Jean Scott or Comp City by Max Rubin, you probably already know a little bit about becoming a “comp hustler” or “comp wizard.” These are players who learn to maximize the amount of comps they receive in exchange for their action.

One way to maximize the comps you get for the money you lose is to play a game with a tiny house edge. If you can play blackjack with perfect basic strategy, you can get the edge in the game down to 0.5%. The average player loses about 4% at blackjack, because the average player doesn’t know perfect basic strategy.

When the casinos calculate your expected loss at the blackjack table, they assume you’re an average player losing 3% or 4%. Since you’re only expected to lose 0.5%, you’re getting comps based on a theoretical loss that’s actually overstated by a factor of between 5 and 10.

Another way to maximize the comps you get is to bet big when you’re being rated by the dealer and the pit boss. “Rating” players is how they estimate your hourly action. Fooling the pit boss is harder than you think.

I was playing blackjack in Kansas City for between $10 and $100 per hand, depending on the count. They rated me as a $10/hand player, even though I was betting more than that on a lot of hands. I complained, but I’m sure they realized I was counting. The last thing they were going to do is rate me higher when they knew I was counting cards.

(I was also a little drunk, so I didn’t notice immediately when they started shuffling the deck after every hand. Counting cards does you no good if the dealers shuffle after every hand.)

Slot

Taking lots of breaks can result in fewer hands per hour than the casino estimates, which reduces your expected hourly loss by a lot. If you’re at a blackjack table dealing 60 hands per hour, you could realistically only play 45 hands per hour by taking frequent bathroom breaks.

What effect does that have on your expected hourly loss?

It reduces it by another 25% or so. Instead of losing $10/hour, you might only be losing $7.50/hour. The casino might be estimating that you’ll be losing an average of $40/hour and base your comps on that.

Expert video poker play can also result in smaller expected losses per hour. In fact, with certain video poker games, the combinations of comps with the tiny house edge can result in an overall positive expected value for the player. That’s an advantage gambling technique, but it’s not one you can realistically make a living at. The edge is too small, and games with those pay tables are usually only available for small stakes. You’d be lucky to make minimum wage playing video poker for comps.

How much of your expected losses can you expect back in comps?

It varies, but the casino calculates that they can afford to give you back 40% of your expected loss in the form of comps. You’ll more often see 20% through the players’ program if you’re a low roller, but you can even increase that amount by taking advantage of coupons and “happy hour” type promotions where you get 2X or 3X your standard comp rate.

How Do Online Casino Bonuses Work? Isn’t That Another Form of Comp?

Online casinos can’t serve you drinks or free food. They can’t really provide you with a free room for the night, either. And since you’re playing from home, they’re unlikely to offer you free show tickets, either.

Slot

Instead, online casinos offer you sign up bonuses and ongoing deposit bonuses. These amount to free amounts of money awarded to your account just for making a deposit—either as a new player or as an existing player.

Bonus hustlers used to take advantage of these offers to generate almost guaranteed profits. A friend of mine once bought a jukebox by taking advantage of casino bonuses at a dozen different casinos and cashing out his winnings.

Online casinos have responded to this by instituting wagering requirements that make it almost mathematically impossible to come out ahead when taking advantage of a bonus. They also watch player behavior closely, and if that behavior resembles that of known bonus hustlers, the casino might refuse to pay you based on “bonus abuse.”

The concept of wagering requirement seems more complicated than it is. Here’s how it works:

You sign up at a casino that offers you a 200% matching bonus on your first deposit of $1000. You deposit $1000, input your bonus code, and the casino adds $2000 to your balance.

You now have $3000 to play with.

But the casino requires you to wager this amount 35 times before cashing out. They also restrict your play to slot machines. You can play blackjack, too, but only 10% of your blackjack wagers count toward fulfilling your wagering requirements.

And you can’t cash out before fulfilling these wagering requirements.

Let’s assume you want to play the slots. A good ballpark estimate for the house edge on a slot machine game is 6%, but who knows? (The casino does, but you don’t.)

To wager $3000 35 times means you must put $105,000 into action.

The expected loss on that much action is 6% multiplied by $105,000, which is $6300.

Since you started with $3000, the mathematical expectation is for you to go broke before fulfilling your wagering requirements.

On the other hand, if you play blackjack, the house edge is only 0.5%. But since the casino only counts 10% of those wagers toward your wagering requirements, you need to make $1,050,000 in wagers before cashing out.

0.5% of $1,050,000 is still over $5000.

Again, that’s more than your starting bankroll, so it’s unlikely that you’ll have money left over after fulfilling your wagering requirement.

You can, of course, get lucky and win more than you’re expected to. I claimed a bonus at an online casino once for $1000, and I hit a $6000 jackpot on my 5th spin of the reels on a slot machine game.

I was able to fulfill my wagering requirements and still have $2000 in profits.

But that’s because I got lucky—not because I took advantage of a mathematical edge given me by the bonus.

In fact, had I eschewed the signup bonus, I could have cashed out the entire $6000. I wouldn’t have been required to finish fulfilling the wagering requirements.

Conclusion

How Do Slot Machines Work At Casinos Cheat

Casino and gambling comps are really cool, but they’re also a tool that casinos use to get you to lose more money than you’d otherwise lose. Understanding how those comps work is the first step in making sure you don’t get taken advantage of.

Some people learn how to take advantage of the comps system in such a way that they gamble practically for free. It’s even theoretically possible to come out ahead because of the comps program. That’s too much work for most people, but it’s nice to know that it’s possible.

The bottom line about comps is that the casino doesn’t have your best interest at heart. They want your money.
