Bally Technologies is among the leading firms that manufacture slot machines and develop cutting-edge gaming technology. The company is based in Las Vegas, Nevada, and was founded in 1968 under the name Advanced Patent Technology. After a series of name changes and acquisitions, the corporation finally took to the name Bally, a trademark originating from Bally Manufacturing Corporation.

Currently, Bally Technologies competes with industry leader IGT and other prominent game design firms like Aristocrat, Bally and WMS. Bally’s history goes way back to the 1930s. The firm is now one of the top companies in industries relating to game design, slot machine manufacturing, operations, distribution of advanced gaming systems and applications for mobile devices.

  • Play Online Popular Slots a Pro! When we think about poker, most people picture Texas Hold’em version of the game, with physical cards. But today, video Poker is a popular casino slot where you can have endless hours of fun and strategy playing online.
  • The 5-line vintage classic penny Slot machine is still one of the most popular Slots games - despite it comes with no bonus rounds to be triggered. The Sizzling Hot relative is one of the most generous Slot machines out there as it features a 1,000x payout when five Lucky Sevens land on a payline.

Whether you prefer popular slots, classic fruit machines, cheap slots or state-of-the-art video slots, we guarantee that you’ll have a smooth, easy and pleasant experience playing with us. Any provider, any.

The organization specializes in the development of reel-spin slots, video slot machines, wide-area progressives and interactive game designs compatible with all iOS and Android devices. The move to mobile derivatives of casino slot games is a recent one though.

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.

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).


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.

Free Spins

As mentioned, the bonus rounds in Playboy slot are unlocked when the combination of 3 to 5 Scatters is formed on the reels, initiating one of the following Free Spins modes:

  • Kimi (unlocked at the initial bonus feature activation): 15 re-triggerable Free Spins with x5 multiplier
  • Sofia (unlocked on the 5th bonus feature activation): 15 Free Spins with Running Wilds. The stack of Wilds increases on every spin.
  • Ashley (unlocked on the 10th bonus feature activation): 20 Free Spins with Rolling Reels and progressive multipliers (up to x5)
  • Jillian (unlocked 15th bonus feature activation): 25 Free Spins with randomly triggered Wild Night Feature which will make up to 5 reels wild.

Twerk Slot by Edorphina

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

The dynamic Battle Feature with bonus points awarded every time your dancer defeats the opponent in the dance-off (or twerk-off, in this case).

Free Spins with Battle Feature

3 Scatter symbols will activate the Free Spins with the Battle Feature, during which one of the girls will be singled out to compete with other dancers. The battle will last up to 6 rounds and whoever scores more points will win. The feature is re-triggered if more Scatters land on the reels, adding 3 more dance rounds.

Risk Game Gamble Feature

Every payout can be increased up to 10 times if the player’s card beats the virtual dealer. You will have four cards to choose from – Joker trumps all hands, and only the player can draw this card. Same value cards will be resolved as a push.

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…

Best Free Slot Machine Games

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.

Honourable Mentions

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.


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.
