OCTGN (Online Card & Tabletop Gaming Network)

Free open-source software for playing card and board games online, supporting Magic: The Gathering, Android: Netrunner, and many others with full rules enforcement against global opponents.

What is OCTGN?

OCTGN (Online Card & Tabletop Gaming Network) is a free, open-source software application that allows users to play trading card games, board games, and other tabletop games online against opponents from around the world. It was first launched in 2007.

One of the key features of OCTGN is its built-in rules enforcement for many popular games. When you play a game on OCTGN, all the mechanics and calculations are handled automatically by the software, ensuring games follow the official rules. This sets it apart from platforms like Tabletop Simulator that provide tools to play games but don't enforce rules.

For each game, OCTGN has a custom script written to model the game's cards, boards, tokens, phases, timing, costs, mechanics, and other components that make the game work. Popular scripted games include Magic: The Gathering, Android: Netrunner, Arkham Horror, Star Wars: X-Wing Miniatures Game, Lord of the Rings LCG, and hundreds more.

OCTGN also facilites online multiplayer matching, allowing users to be paired up with other players looking for a game in their region or language. Chat and other social features make it easy to communicate with your opponent while playing. Since everything runs in your browser, there's no need to download or install files.

The software is community-built, open source, and maintained by developer volunteers. Anyone can contribute to building and improving game scripts and features. The community has kept it running as a passion project since 2007.
