The Syndicate

Made some updates to the OP.

I'm sure there are various places where you can play board games online, but today Ambray/Sofi introduced MP and I to Dominion online. We love Dominion so it was loads of fun getting to play it with her.

So I figured we can keep a running list of websites here in this original post where we can play tabletop games together online. Then whenever someone feels like playing one they can drop a post in here and see if anyone wants to hop online and play with them.

Stand alone games that can be played in browser:
Dominion
Avalon/The Resistance
Chess


Stand alone games that require a download:
Subterfuge (for iPhone or Android mobile platforms)


Tabletop sites with multiple games:
Board Game Arena Includes: Carcassonne, Puerto Rico, Hanabi, Tokaido, Colt Express, Love Letter, Terra Mystica, Race for the Galaxy and many more...
Tabletopia (Browser or through Steam) Includes: Near and Far, Islebound, Terra Mystica, Vast, Love Letter, Secret Hitler, Santorini and many more...

If you have a tabletop game website you would like to add to this please PM me and I will edit it into the OP.
