How to Download, Install & Play
Step-by-step: get the 3Sigma launcher, install it, and start your first game — plus Mac and system-requirement answers.
Getting into a 3Sigma game takes about three minutes and three steps. This guide walks through downloading the launcher, installing it on Windows, and starting your first title — plus the answers to the things people ask most: system requirements, Mac options, and what to do if a game won't start. Once you're in, a good first pick is Jomere.
Download, Install & Play In 3 Steps
- Download the launcher. Confirm your age on the site, then click Download to get the official 3Sigma launcher.
- Install it. Run the installer and choose where to put it. The launcher is a normal Windows desktop app; installation takes a minute.
- Open the launcher and play. Launch it in desktop mode, pick a game from your library, install it, and press play. Updates and new titles show up in the same place.
Prefer to start right now? Use the Download the launcher button — the site checks that you're on a PC and hands you the installer.
System Requirements
The games are light by modern standards — most Windows PCs from the last decade run them comfortably. Here are the minimum specs.
| Requirement | Minimum |
|---|---|
| Operating system | 64-bit Windows (10 or 11 recommended) |
| DirectX | Version 11 |
| Processor | 2.0 GHz Core 2 Duo or better |
| Memory | 2 GB RAM (4 GB recommended) |
| Storage | 20 GB available (minimum) |
| Peripherals | Mouse and keyboard |
32-bit Windows is not supported — you need a 64-bit version to install and run the games.
Playing On Mac Or iOS
The launcher is a Windows program, and a native macOS build is still in development. Until it ships, Mac users have solid options:
- Apple Silicon Macs (M1/M2/M3): run the Windows version through Parallels Desktop (paid), Whisky (free), or CrossOver (paid).
- Intel Macs: use Boot Camp to dual-boot into Windows and run the launcher natively there.
- iPhone / iPad: there is no iOS version — the games are desktop software and need a PC (or one of the Mac methods above).
Account & Library Setup
Once you download and install the launcher, you create your account inside the 3Sigma Launcher application. This account keeps your games library, saved progress, and updates organized across your sessions.
How Updates & New Titles Work
Once it's installed, the launcher becomes the single place your games live. New titles and patches show up inside it automatically — you install or update with one click, and there's nothing to re-download from the website. And because every game runs locally after it's installed, there's no streaming and no buffering: the launcher keeps each title in full ultra-high-definition quality on your own drive, ready to play offline whenever you want.
If A Game Won't Start
Most launch and performance problems come down to graphics drivers, missing runtime libraries, or background apps fighting for resources. Work through these in order:
- Check the requirements. Confirm your PC meets the minimum specs above — an unsupported OS is the most common cause.
- Reinstall your GPU drivers cleanly. Use a tool like DDU to fully remove them first, then install the latest from NVIDIA or AMD.
- Reinstall the Microsoft Visual C++ Redistributables. A missing runtime library stops many PC games from launching.
- Close background apps and overlays. Discord, GeForce Experience, and similar overlays can block a game from starting.
If it still won't run, the support page has the full troubleshooting list and a way to reach the team with any error codes you see.
