Best Odds Slot Machines Las Vegas
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.
Slots: Odds of Winning Around 1 in 49,836,032. You play slots by putting money into a slot machine and pulling a lever or pushing a button to spin a wheel. Depending on where the wheel lands, you win or lose. MGM Grand Las Vegas. The MGM Grand is located at the south end of the Strip. It’s easy to spot the MGM Grand casino—it’s a massive emerald-coloured complex with a 45-foot bronze lion out front. The MGM Grand covers over 170,000 square feet and has 3,000 slot machines (with denominations ranging from $0.01 to $1,000.
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.
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.
As evidenced above, the best places around Las Vegas to play slots are the Boulder Area (6.10% casino win percentage) and North Las Vegas (7.24% win percentage).
In an abnormal twist, slots were slightly tighter in 2020 downtown (8.24% win percentage) than on the Strip (7.95% win percentage). Historically, slots downtown have been reliably looser than those found on the Strip.
In another rare twist, Slots on the Las Vegas Strip loosened slightly year over year in 2020 vs. 2019 (8.16% in 2019 vs. 7.95% in 2020), while slots downtown tightened by a slight margin (7.78% in 2019 vs. 8.24% in 2020).
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.
Where to Find the Loosest Penny Slots in Vegas
Since penny slots are the most popular denomination with players, we also broke down where the loosest penny slots in Vegas can be found by region. Since the data below looks exclusively at the penny denomination, it’s untainted by video poker and thus provides a clearer window into where looser slots can be found across Las Vegas.
Clearly, there is again a correlation between an area being “touristy” and higher slot hold rates. Downtown and Strip penny slots came in as the tightest with casino win percentages of 11.26% and 11.45% respectively.
Similar to our previous data set that looked at all denominations, penny slots more apt to pay out can be found in the Boulder (9.61% win rate) and North Las Vegas (9.71% win rate) areas.

So, What Las Vegas Casinos Have Looser Slots?
Although most players aren’t typically able to tell the difference between a “tight” or a “loose” slot, the data suggests getting away from the Strip and Fremont Street will give you a slightly better chance of winning.
Casinos that fall into the looser Boulder and North Las Vegas reporting zones are broken down below. Note that these aren’t 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.
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.

The Denomination You Play Matters
Slot denominations also play a role in finding lose machines which is demonstrated by the statewide data below. In 2020, penny slots were the tightest variety of slot in Nevada by a large margin with a 9.74% win percentage, with quarters coming in a distant second place at a 7.31% win percentage.
Although the above data is slightly “polluted” by video poker at the quarter denomination and up, the view is still beneficial to demonstrate the poor bet penny slots are comparatively. It is also interesting to note the correlation between denominations and how loose or tight 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 yourself a better chance of winning by playing the same bet on a higher denomination machine. We would also recommend that penny slot players brush up on their video poker skills as the returns are more favorable in comparison.
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 breakdown of 2020 slot data will help you on your quest in finding the loosest slots in Vegas!

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.
