About forge

Forge is a rules engine for Magic: The Gathering, developed by a community of volunteer programmers. It lets players play the card game through single-player modes and online matches. The homepage lists builds for Windows, Mac, Linux, and Android, and describes iOS support as early stage. Forge operates independently and is not affiliated with Wizards of the Coast.

The main modes are Adventure Mode, a single-player game with an overworld map where players collect cards and items, and Quest Mode, which offers focused single-player games without the map. Players can also play against AI opponents in Sealed, Draft, Commander, and Cube formats. Desktop installs require Java 17 or later. Android requires Android 11 and at least 6GB of RAM, and the app must be allowed to install unknown apps so it can update itself. On iOS, the app must be built as an IPA file and sideloaded from a computer using developer mode, without a jailbreak. The homepage lists a GPL-3.0 license.
