Parlor

Parlor is a multiplayer platform where you can challenge your friends to tavern, parlor and tabletop games. Each game is its own self-contained plug-in, and Parlor handles all the fiddly bits - finding who has what, invites, turns, and keeping all screens perfectly in sync. For reference, a few games are shipped with the addon.

What's on the table

Game
Artillery	Gnome vs. goblin: lob shells across destructible terrain, mind the wind.
Gomoku	Five in a row on a 15×15 grid.
Reversi	Flank, flip, watch the board swing.
Sternhalma	Chinese Checkers for 2–6 players. Hop your marbles home.
Tic-Tac-Toe	The classic. Also the starter kit for would-be game authors.

More games, polish, etc. coming soon if there is interest in this idea.

Want to build a game?

You write the rules and draw the board; it handles networking, sync and the whole session lifecycle for you. Tic-Tac-Toe is the reference module to copy from. Hopefully your only restriction is that your game idea is turn-based.
