Interactive Porn Games for PC, Explained
Welcome to the 3Sigma wiki — the place we answer the real questions about interactive porn games: what they are, how they play, how to install them, and what happens in each of our stories. Every question below has a short, straight answer, and a link to the full guide when you want the whole picture. If you are brand new to the format, the first three answers cover most of it.
New here? Start with the basics
If you have never played an interactive porn game before, these three answers cover almost everything people ask first.
What are interactive porn games?
Interactive porn games are adult games where your choices shape the scenes, the relationships, and how the story ends. 3Sigma builds them as FMV — full-motion video filmed with real actors — so you steer a real story instead of watching a fixed clip.
Full guide: What are FMV games?Are 3Sigma's games made with real actors?
Yes. Every scene is filmed with professional performers on real sets — no 3D models, no rendered dolls, and no AI-generated images. When a character reacts to a choice you made, that is a real performance on camera.

You confirm your age, download the official 3Sigma launcher for Windows PC, install it, and launch any game directly inside the application.
How to get startedGetting the games running
Everything about installing and playing on your own machine.
How do I download and install a game?
Confirm your age, download the 3Sigma launcher, run the installer, then launch your chosen game from inside it.
Step-by-step guideWhat are the system requirements?
A 64-bit Windows PC with DirectX 11, 2 GB of RAM and 20 GB of free space is enough. The games are light by modern standards, so most PCs from the last decade run them comfortably.
Full requirementsCan I play on Mac or my phone?
The launcher is Windows software. Macs can run it through Parallels, Whisky, CrossOver, or Boot Camp, and a native macOS build is in development. There is no phone version — the games are desktop software.
Mac & compatibilityAbout the games & the studio
What actually makes these games different, and how the platform works.
What makes 3Sigma different from other adult games?
Three things: the scenes are filmed with real actors instead of being animated or AI-generated, every title is built around real choices with multiple endings, and they run through the studio's own launcher rather than a browser. The result plays like a film you are the lead in.
Why FMV, not 3D or AIAre 3Sigma games on Steam?
No. Steam does not allow explicit adult games, so 3Sigma built its own launcher — a kind of Steam for adult games — to install, update, and launch every title from one place.
How the launcher worksIs downloading safe and private?
You confirm your age before downloading the launcher installer. It installs like a standard Windows desktop application, and you set up your account inside the launcher to access and manage your games library.
Download & install guidePlaying, choices & endings
How the interactive part actually works once you press play.
How do choices work in the games?
The scene never pauses. You decide what to say and do in the moment, and the filmed story branches around your call — who you seduce, who you trust, who you betray. Say the wrong thing and a path can close for good.
Gameplay mechanicsCan I replay for different endings?
Yes, and you are meant to. Each title has multiple endings, and a single playthrough only shows you one path, so replaying is how you reach the branches, scenes, and outcomes you missed the first time.
See Jomere's outcome statsDo the games have real stories, or just scenes?
Real stories. Each title is a self-contained plot — an escape, a murder investigation, a seduction game — with characters, stakes, and usually a clock. The adult scenes are part of the story, not a menu bolted onto it.
How the stories workWhich games can I play?
3Sigma makes four interactive FMV titles, each a self-contained story with its own cast, choices, and endings.
