Best Slot Machines On The Strip
The gaming software design has come a long way since the first electronic descendants of the 19th century’s Liberty Bell were lined up in the casino halls, featuring the PG-13 imagery and naïve aesthetics. As the market evolved, slot machines developed into more complex platforms, but the true revolution was sparked with the arrival of online casinos and the expansion of internet gambling.
All slot machines The Strip: 92.98% Downtown: 93.42% Boulder Strip: 94.96% N. Las Vegas: 94.36% This report defines “slot machines” as all electronic machines, including regular slots, poker and keno machines. 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.
The simple 3-reel machines were pushed aside to make room for visually supreme releases with more sophisticated structure and features, going as far as to adapt the slots to Virtual Reality technology.
The new age also created the need to provide the players with more engaging content, and the usage of the popular sex in advertising method did not bypass the gambling industry. To maintain the competitive edge, the software developers started looking for new ways to appeal to their target audience, launching slots of a more provocative nature (for both land-based and online gambling markets).
While these are still not something that you will find in just any venue, adult content slots that feature erotic (or even soft pornographic material in some cases) have a solid fan base, attracting those with more explicit taste.
So, if you ever find yourself feeling particularly naughty, the adult slots listed below might warm up a lonely night and provide a few hours of uncensored fun.
Scandinavian Babes by Play’n GO
Compared to some releases from this list, Scandinavian Babes slot is quite toned-down, leaning more towards moderate erotica. Played on 5×3 reel grid across 15 adjustable lines, this Play’n GO online slot allows the players to bet as little as $0.01 on a single active line, or press the bet to $18.75 per spin (by activating all 15 lines, increasing the denomination, and wagering up to 5 coins per line).
The volatility is between medium and high and the hit frequency of bonus features is somewhat low.
Bonus Features
The game benefits from Free Spins that may be particularly difficult to trigger at times, but the base game wins will still land frequently.
Free Spins
Free Spins are activated by the stacked Wild Brunette on the first and last reel. This will set in motion 15 bonus rounds, during which reels 1 and 5 will hold still while the rest of the columns are spinning.
Free Games
A classic picking game that can award up to 150x multiplier. All you need to do is select one of the 3 dancers and a cash prize will be revealed (along with the other two prizes that you did not get).
Gamble
This feature activates after every win, enabling you to double the payout every time you guess the colour of the card facing down. The payouts are higher if you manage to guess the suit as well. The feature is, of course, optional, and you can simply collect the money and continue the session without gambling.

Playboy Slot by Microgaming
Playboy by Microgaming is a 243 ways to win slot launched in 2013, generating up to 1,215,000 coins per spin. Despite the legacy of the brand, Playboy slot designers have shown an impressive amount of restraint, opting for a sexy rather than a raunchy interpretation of the theme (you can check our comparison of all Playboy slots).
Bonus Features
The Bunny is the Wild symbol that doubles the payout every time it completes the winning combination. It can also replace all other icons except for the Stack of Playboys Scatter, which triggers the Playboy Club Free Spins.

Those with an appreciation for curves will enjoy Endorphina’s 5-payline slot immensely. Not only does the 2016 release celebrate the female form in all its glory, but it also produces up to 250,000 coins per spin.
The gameplay is quite simple, and Endorphina seems to rely on derrières and upbeat music to keep the players engaged.Bonus Features

Benchwarmers Football Girls by Playtech
This slot combines two ultimate fantasies of an average male – football and provocatively dressed ladies. Benchwarmers Football Girls is a 30-payline game that’s suitable for both high limit slots players and recreational players. The lines can be adjusted, allowing you to bet $0.20 – $3,000 per spin.
The Benchwarmer Girls are the high paying symbols, with the eager supporter of the Italian football club as the highest-value icon. The next in line are four equally enthusiastic females, who were so eager to see the game that they rushed to the court wearing nothing but their underwear…
Bonus Features
The slot offers Free Games with the Bench Warmer feature and Football Bonus where you can reveal cash prizes.
Free Games with Bench Warmer Feature
The Free Rounds are activated by 3+ Bench Warmer Scatters and before the feature is initiated, you can select any of the Benchwarmer Girls to cover the first reel. The symbol will remain locked on the reel for the next 4 spins – the rest of the girls will not land on the grid during the feature.
Bench Warmer bonus can be re-activated an indefinite number of times.
Football Bonus
If a Bonus symbol lands on the reels 1 and 5, the Football Bonus picking game will be initiated, prompting you to pick 3 out of 5 balls and reveal cash prizes. Unfortunately, this feature cannot be re-triggered.

Red Lights by Tom Horn Gaming
A steaming hot release, inspired by the infamous Red Lights district in Amsterdam, where love (or lust) is for sale day and night. Instead of using real-life footage, Tom Horn Gaming decided on a more tactful approach (for the lack of a better expression). This will not diminish the eroticism of the slot, and even the animated girls are quite capable of raising the players’ heartbeat levels.
Bonus Features
The slot features two Wild Symbols which can replace all other icons and activate the Free Spins.
Sticky Expanding Wild
The Free Spins start when one of the two Wild Girls lands on reels 1 or 5, locking into the landing position and expanding across the entire reel. Additional spins can be triggered if more Wilds appear on the grid. The payouts generated in the Free Spins will be doubled if a single Expanding Wild is locked on the reel or quadrupled if two Wilds share the grid.
Strip Gambling Feature
All payouts can be boosted in the Strip Gambling Feature, which is quite cheeky, inviting you to strip one of the girls. To double the winning amount, you will have to guess which of the two symbols hides behind the silhouette in the middle of the game screen. Every time your guess is correct, the amount will be doubled.
Mystery Win Feature
Mystery Bonus is awarded randomly – a combo of 3 X symbols can form a combination in the middle of the screen and award a cash prize on any spin.

Delicious Desires
Probably the most explicit slot on the list, Delicious Desires goes way beyond sexy and enters the reals of soft porn.
It is played on 9 paylines and every time a winning combination is formed, the featuring ladies become (believe it or not) even more loose, not leaving anything to the imagination.
Bonus Features
The main attraction of the slot, apart from the hot ladies, is the Free Games feature awarding trebled prizes.
Free Games
Free Games symbol starts 15 re-triggerable free spins, but only if it lands on the first and the last reel. During the bonus, all payouts will be multiplied by 3.
Gamble
One other way to increase your winning before collecting it would be to use the Gamble option. To double the amount, you must guess the colour of the card facing down. Or, to be more specific, you will need to opt for either Black or Red and then stop the flashing card.

The next table shows the average return by location.

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.
Best Slot Machines On The Stripes
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.
