Introduction
The following table ranks the Las Vegas casinos according to the looseness of their video display reeled nickel slot machines. The returns are based on a sampling of five different types of machines. The data collected goes back as far as October 2001 so the information is a bit dated.

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%.
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.
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.

Casinos across Nevada are required to report revenue figures to the Nevada Gaming Control Board to include what percentage of wagers they held as profit on slot games. A nerdy annual tradition of ours is to dig into that real world data from the previous year to help our readers find the loosest slots in Las Vegas.
Unfortunately, the data we have access to isn’t granular enough to tell us how loose or tight slots were at individual casinos. Rather, the reporting will highlight groups of casinos based on where they are located (ie The Strip, Downtown, Boulder, etc). We’ll make sure to point out what casinos reside in zones identified as having looser slots.
As a matter of housekeeping, casino slot “win percentage” is defined as the percentage of the total amountwagered by the player that the casino held as profit. For instance, a 10% casino win percentage means the casino, on average, kept 10 cents of every dollar wagered on slot machines.
Best Slot Machines Odds
Example: A player put $20 into a slot machine and made her money last for a while playing a total of $200 in spins before losing it all. The total amount wagered by the player was $200 and the casino won, or held, $20 resulting in a 10% casino win percentage.
Now that we cleared that up, lets dig into where you can find slots that are more apt to pay out around Las Vegas.
Where you play matters. The graph below details casino slot win percentages by area, which lumps together all slot denominations. You can quickly surmise that casinos in tourist centers hold a larger percentage of slot play as profit.
Slot Machine Odds Percentage
As evidenced above, the best places around Las Vegas to play slots are the Boulder Area (5.78% casino win percentage), North Las Vegas (6.71% win percentage) and Downtown (7.78% casino win percentage). The Strip featured the tightest slots by a wide margin at a win percentage of 8.16%.
Unfortunately, slots tightened up versus last year on both the Strip (8.12% in 2018 vs. 8.16% in 2019) and on Fremont Street (7.64% in 2018 vs. 7.78% in 2019) by a slight margin.
Since penny slots are the most popular denomination with players, we also broke down where the loosest penny slot machines can be found.
Clearly, there is again a correlation between an area being “touristy” and higher slot hold rates. Downtown and Strip penny slots come in with casino win percentages of 10.94% and 11.59% respectively.
Similar to the data that looked at all slot denominations, penny slots more apt to pay out can be found in the Boulder (9.36% win rate) and North Las Vegas (9.28% win rate) areas.
Casino Slots Odds Of Winning
Although most players aren’t able to tell the difference between a “tight” or a “loose” slot, get away from the Strip if you want to give yourself a slightly better chance of winning.
Casinos that fall into the looser Boulder and North Las Vegas reporting zones are broken down below. Not the most scenic areas, but if winning is more important to you than bright lights, fountains, and celebrity chef restaurants then order up an Uber and make the trip.
Odds Of Winning On Slots
Casinos in the Boulder Area: Sam’s Town, Eastside Cannery, Arizona Charlie’s, Boulder Station, Sunset Station, M Resort, Fiesta Henderson and Green Valley Ranch.
Casinos in the North Las Vegas Area: Jerry’s Nugget, Silver Nugget, The Cannery, Fiesta Hotel and Casino, Texas Station, Cannery and Aliante.
Keep in mind that video poker also figures into these slot statistics. Lower casino win percentages away from the Strip are in part, but not completely, due to better video poker pay tables offered by establishments away from tourist centers.

Slot denominations also play a role in finding lose machines which is demonstrated by the statewide data below. In 2019, Megabucks was the tightest variety of slot in Nevada (12.78% win percentage), followed closely by penny slots (9.93% win percentage).
What Are The Odds Of Winning Slot Machines In Vegas This Week
Taking a look at the graph above, there is a clear correlation between denomination and how loose their corresponding slot machines are. Generally speaking, the higher the denomination, the looser the slot.
If you’re a penny slot player that plays 75 cents per spin or more, you would likely give your self a better chance of winning by playing the same bet on a higher denomination machine.
While looking at the numbers is a fun exercise, ultimately, the random number generator could select you as the next big winner anywhere. Good luck, and hopefully our break down of 2019 slot data will help you on your quest in finding the best paying slots in Vegas!
