The Ineffable Plan is a Good Omens themed card game based on the game Fluxx.
You can play the game online at VirtualTableTop.io, an open source platform for playing board games online. Note that this is just a shared space where multiple players can move pieces around; it is not a computer game, and there are no rules implemented.
To host a game, click the link above, enter your player name and click on “Create Room”. The game will then appear on your Game Shelf (you’ll also be able to see the whole public game library underneath). Details, rules, and some information about how to use this implementation will also appear. In the sidebar, click on “Play.”
To invite more players, send them the URL of the room. You can also click on “Players” and then “Share room URL.”
