Best Vegas Slot Machine Odds
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.
Slots With The Best Odds – High RTP Games. How to win while playing slot machines? This is one of the most common questions among slot aficionados and one of the biggest mysteries of online gambling. Whether they play classic, video or progressive slots, punters are looking for ways to make a slot machine work for them. How to Pick a Slot Machine in Las Vegas Casinos. How to Beat the Odds in Las Vegas Casinos. Jodi Thornton-O'Connell, Leaf Group Updated June 13, 2018. Live poker has the best odds.
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.

The above sign can be found across the street from the Palms. Although I did the study Anthony Curtis published it in the LasVegas Advisor, which is how it become well known. The'...' in the sign encompases quite a bit of information,which was conveniently left off the sign. Actually the study only says that the Palms had the lowest nickel video slotsof the casinos surveyed in Las Vegas. The small print at thebottom says, 'Independent study conducted between November2001-February 2002 on Austin Powers, Fortune Cookie, Reel'em In, and Wheel of Fortune games. They left off LeopardSpots, and the study began in October.
Observations
There seemed to be no truth behind slot placement myths. Machines on the end of a bank did no better on average than those in the middle. There was also no correlation between return and proximity to such things as the main door, table game pit, high traffic areas, and low traffic areas.
Most casinos were very consistent in their slot returns.If one nickel machine had a return of x% then all others like it also returned x%. However some casinos did mix up loose and tight machines, most notably Treasure Island and the California casinos.
Methodology
A kind and anonymous source provided me with par sheets for the games in question. The EPROM (Erasable Programmable Read Only Memory) chip is what tells the machine the order of the symbols on the reel, in some cases how the stops are weighted, how much each winning combination pays, and any other pertinent information about how much the machine pays.It is up to the slot manager to select which EPROM chip to order according to the return percentage desired. On atypical game there might be about 8 different possible return percentages, ranging from about 85% to 98%.
Vegas Best Slot Machine Odds
Each of the different par sheets has five sets of distinct reels. On video display slots the stops are not weighted; in other words all stops are equally likely. The distribution of each symbol on each reel is what determines the theoretical return of the machine. For example a higher paying machine may have more of the higher paying symbols.
On the machine itself three consecutive symbols arevisible on five different reels. By comparing actualobservations of results to the par sheets it is possible todetermine which reels the machine uses, and thus which par sheet and which return. There are various three-symbol combinations that appear in at least one but not all par sheets. So if one of these combinations occurs on an actualmachine it narrows down the possible par sheets. By playingenough the player can narrow down the possible par sheets tojust one.
To help identify the unique combinations I wrote a computer program for each game, which had the exact reel order of all 5 reels of all the par sheets. The program then counted the number of par sheets with each possible three-symbol combination. If the number was greater than 0 and less than the maximum then that combination was identified along with the associated par sheets it belonged to.
It is then a matter of simply playing the game and comparing the outcomes to the list of partially unique combinations. It only takes about 5-10 plays per machine to narrow down the possibilities to just one par sheet.
The averages in the table are actually an average of averages. For each kind of machine at each casino I took an average return. Then I took the average of these averages over the five kinds of machines I tested for.
Slot Machine Definition
There is some confusion about what constitutes a 'slot machine' or 'slot.' My definition, and that of most gamblers, is a gambling machine with either actual spinning reels or video representations of the them.
Casino Best Odds Slot Machine
People in the gaming business and regulators generally refer to a slot machine as any gambling machine, including reeled slots, video poker, video keno, video blackjack,etc.. For purposes of statistics both casino managers and regulators combine all the electronic gambling machines together. For example, the Slot Chart in Casino Player magazine and reports by the Nevada Gaming Control Board do not isolate just reeled slots but consider all electronic games a 'slot.' Therefore my return percentages should not be expected to agree with those reported by the casinos or regulators. As far as I know mine is the only source to isolate just the return of reeled slots.
Acknowledgements
I would like to thank Rob Feldheim for helping with the slot play and record keeping. Rob helped me with most of the casinos on the east side of town and part of downtown. I would also like to thank par Sheet Pete (not his real name)for providing the par sheets, without which this project would not have been possible.
