Slot machines are an extremely popular form of gambling. The premise is simple: you insert a coin, pull a lever, and reap in cash rewards if the symbols on the reels align in a certain way. Slot machines test your luck and intuition, and, despite the simple rules, they are not boring in the slightest.
When you visit a casino, all the action appears to be happening at the tables. But when it comes to ease of play and popularity, slots come out on top. In fact, casinos dedicate roughly 80% of their gaming floor to slots. Only 20% is for table games.
The reason? Slots are more popular and account for more revenue than all other gambling sources combined. And for good reason. Playing a slot machine doesn’t require any gambling knowledge. On top of that, you can bet as little as $0.01.
What slots and table games have in common, however, is the enforcement of a withholding tax. If you’re one of the millions who visits Las Vegas annually, you need to remember that your winnings could be subject to a 30% withholding tax by the Internal Revenue Service (IRS).
Fortunately, Refund Management Services (RMS) can help you reclaim a portion or all of your withheld winnings.
Finding the Loosest Slots in Las Vegas
It’s not hard to find a slot machine in Nevada. In fact, there are over 490,000 slots and gaming machines in Clark County alone (the county where you find Las Vegas). And they’re not just located in casinos. You can find slot machines in the airport, gas stations, and convenience stores.

What is hard, though, is finding slot machines with the best payouts. After all, no one likes to go into a casino and lose $100 on the slots in 30 minutes. The goal is to win, or at least make your money last longer.
Thanks to increased competition in gambling hubs like Las Vegas, Reno, and Atlantic City, casino operators are battling for customers. To keep customers coming back, many casinos are increasing the number of jackpots at their slot machines.
All slot machines work on a payback percentage that the casinos can set. They can make a slot machine tight or loose. Loose slot machines increase the chances of a player hitting a payout. This creates excitement and helps keep players in their seats on the gambling floor.
For slots aficionados, it’s all about finding the loose machines. Not surprisingly, casinos do not advertise which machines are loose or the payout percentages of individual machines.
But that doesn’t mean you can’t do a little digging and find out which kinds of slot machines have the biggest win percentages. It turns out, you need to spend money to make money in Las Vegas.
Best Slots to Play in Las Vegas
Statistics from the Nevada Gaming Control Board show which slots offer the best payouts in the order of the denomination played. In June 2016 in Clark County, Megabucks progressive slots posted the worst win percentage at 85.15%.1
What that means is, for every $100 you spend, you can expect to win $85.15. Megabucks progressive slots generally have the worst win percentage because the huge jackpot outweighs the bad odds.
The best win percentages came from high-roller slots. Slots that accept denominations of $5, $25, and $100 returned 94.05%, 94.97%, and 94.35%, respectively. While you can lose your money faster with high-roller slots, the payout percentages are always better (on all slots regardless of the denomination) if you get the maximum amount on each spin.
The most fruitful games, when it comes to odds and cost, are the nickel and quarter slots. In June, nickel slots had a win percentage of 94.2% while quarter slots paid back 93.06%. Next to Megabucks, penny slots have the worst win percentage, returning 88.83%.

Casino Slot Winnings Subject to 30% Withholding Tax
Non-U.S. residents who win a significant amount of money playing the slots at any casino or gaming facility in the United States are subject to a 30% withholding tax by the IRS.
In the U.S., winnings from casino games and other games of chance (racetrack, game show) are considered income. If you win $2,000 playing the slots, the casino will pay you $1,400. The IRS keeps the rest. But if you live in a country like Canada, which has signed a U.S. tax treaty, you may be eligible for a refund.
There are a number of countries that currently do not have a U.S. tax treaty. However, if you reside in any of the following countries, you could still be eligible for a refund: Australia, Bahrain, Barbados, Brazil, China, India, Indonesia, Israel, Kuwait, Mexico, Malaysia, Monaco, New Zealand, Norway, Saudi Arabia, Singapore, South Korea, Switzerland, Taiwan, Thailand, and the U.A.E.

How To Slot Machines Work
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.
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.
How Do Slot Machine Work
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
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.
How Do Slot Machines Work In Vegas Besides
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.

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.
How Slot Machines Work Inside
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.
