The Best Hentai Sex Games of 2021

Our picks for the top Japanese erotic games.

Japan’s philosophy, art, cuisine, technology, and architecture have had a huge influence on the rest of the world. And, of course, we can’t overlook the impact of the culture’s approach to merging video games and sex, resulting in the unique category of adult hentai games.

For those familiar with the genre, you can scroll down to view our list of the best hentai sex games. Or, if you’d first like a primer on the term “hentai” and its roots, we offer a brief summary in the following paragraphs.

What does hentai mean?

Like so many Japanese words used by non-Japanese speakers, hentai has drifted quite far from its original meaning. For English speakers, it’s practically become a euphemism for anything pornographic that’s either created in Japan or mimics Japanese aesthetic.

In actuality, hentai broadly means ”perversion”—specifically in regards to sex, but mostly it isn’t used to describe sexually explicit works. Instead, the Japanese use a wide array of words to define various types of erotica. For example, something that is playfully erotic but not necessarily explicit is called “Ecchi.” Meanwhile, “Yaoi” is used to describe anything romantic (and sometimes sexual) that involves male-identified characters.

When the Japanese get general, they usually use the prefix “Ero.” So, when describing a sexually explicit video game the correct term is “Eroge,” meaning “erotic game.” However, it would be awkward to correct every game we've listed here. So we’re going stick with using hentai to convey its international meaning when referring to Japanese or Japanese-inspired sex games.

Hentai Heroes

One of the most popular English-language hentai games online is Hentai Heroes [NSFW], with more than 10 million registered players.

In the style of a visual novel and RPG game, it follows a “Hero” on a sexual quest to save hentai girls from bad guys and then satisfy them. The online game is free to play and geared toward straight players.

Gay gamers, on the other hand, can play the queer version called Gay Harem [NSFW]. It's full of ripped and hard-bodied studs eager to join the Hero's harem of hot men.

Hentai Sex 3D

Next our on list is Hentai Sex 3D [NSFW]. The sex game is a relative newcomer and is getting a top spot because of its super impressive and realistic graphics. We love the attention to sexual physics.

You can create and interact with your own erotic scenes and view them from multiple camera angles. There's a wide selection of female models and developers update the game reguarly with new characters and sex poses.

Project QT

The gaming site Nutaku [NSFW] is the leading online hub for hentai sex games. You won't be disappointed by its wide selection of titles.

Although many games are primarily for people interested in sex with female characters, the site launched an LGBTQ+ sex game section last year.

It is one of the best resources for browser-based games and offers a few titles we’ve chosen for our list of the best hentai sex games.

The first we'd like to mention is Project QT [NSFW]. a hot RPG puzzle game that goes beyond basic puzzle game mechanics. Players must recruit their sexy team of heroines to battle against an evil infection taking over the globe.

Hentai 3D

While not a traditional hentai game, the folks at thriXXX have created something that is arguably even better, and well worth including in our list: Hentai 3D [NSFW].

A comprehensive adult sex game allowing players to create their own unique hentai experience, Hentai 3D offers several features. They include the option to make your own X-rated animated hentai movies, pictures, and books. What’s even more impressive is the hentai game also showcases a wide range of figures and models to play with, including anime staples like sex robots, vampires, cat girls, and much more.

Another benefit to thriXXX's take on hentai is you can check out what other players have created and share your own works with them as well.

Also, if you want to truly immerse yourself into this manga-style sex simulation game, you’ll be happy to know Hentai 3D supports Vstroker [NSFW]. So you’ll be able to feel the erotic action as it unfolds. Not bad!

While Hentai 3D [NSFW]. is PC only, many Mac users reported that the game is still playable using Apple’s own Bootcamp as well as PlayOnMac.

Kamihime Project R

There are many ways to play hentai sex games. However,  most that are available via CD or direct download favor PCs rather than Macs. Fortunately, for those without a PC, there are several excellent browser-based titles available.

At the top of its own list, and more than worth including in ours, is Kamihime Project R [NSFW]. Basically a turn-based fighting game, with fantasy elements, this title has a lot going for it.

First, the gameplay is actually pretty competent—though on the light side. Second, the scenes that play for a successful battle aren’t just sexually explicit but also animated. This puts Kamihimi Project R quite a bit ahead of many other hentai games, which often just use still images.

Millennium War Aigis

Then there’s Millennium War Aigis [NSFW]. In this case, the game is tower-defense. Again, this online sex game is in a fantasy setting where you have to drop various units onto a battlefield to defend yourself as well as take out your opponent. Unlike Kamihime Project R, this hentai sex game uses erotic still images instead of animated ones, though the variety and the entertaining gameplay more than makes up for it.

Flower Knight Girl

For our final browser-based hentai game, we chose Flower Knight Girl [NSFW]. We love girls squads! In this action-adventure roleplaying game, you get to lead your very own troupe of beautiful and powerful Flower Knights. Equip these strong warriors with tools and skills to fight enemies that destroyed the once-peaceful world of Spring Garden.

This game is fun because you can form strategic alliances and join forces with other players to cover more ground. The sexy part comes in when you surprise your girl squad with gifts in order to ramp up their affection toward you. That's when you are rewarded with tantalizing hentai sex scenes.

Starless: Nymphomaniacs' Paradise

If you are interested in a more traditional PC Japanese Hentai experience, there are quite a few importers selling erotic games.

One title that is worth looking at for a good introduction into hentai games is Starless: Nymphomaniacs' Paradise [NSFW]. While not as outrageous as other titles, its simplicity, in both subject matter as well as gameplay, is alluring and accessible. Its style is reminiscent of a dating sim, where character interactions can lead to several different endings. Visually, it’s a series of still images with original Japanese voice work that includes English subtitles. Alas, it’s one of those titles that’s PC only.

No, Thank You!!!

One of the best Yaoi Hentai games is No, Thank You!!! With engaging characters, hot sex, and an interesting storyline, this title is frequently on the top of many gay hentai sex game lists—so it definitely deserves a spot on ours as well! Designed by Shigeo Hamashima, it’s another example of a visual novel in which choices in the gameplay will reveal a series of explicit images.

Japan and censorship

It’s worth mentioning another thing about hentai games: censorship. While the Japanese constitution allows for freedom of expression, its criminal code has been read by the authorities to mean that all sexually explicit materials should have images of genitalia obscured.

This is why it is still common to see a digital mosaic overlaid on all kinds of hentai materials. However, those creating hentai-inspired games—as well as Japanese developers understanding the value of their overseas audience—have been bucking the system and releasing fully explicit titles.

A whole hentai world

In our picks for the best hentai sex games, we’ve tried to offer you ones catering to different game styles, platforms, and sexual preferences. However, there really is no way we could cover the vast range of hentai games that are available, neither from Japan itself nor all the international offerings.

The good news is that, if our list has intrigued you, there’s now a whole world of erotic games to discover and enjoy. And, who knows, maybe you’ll learn some Japanese along the way.
