Connect Six for Salesforce

Two-player Connect Six (Connect6), built as an unlocked package. Players go head-to-head on a 19×19 board inside Lightning Experience, and moves show up on both screens in real time.

Rules

• Black places one stone on the opening move.
• After that, each player places two stones per turn.
• The first player to get six or more in a row (across, down or diagonal) wins.

What's in the package

Component	Purpose
Connect_Six_Game__c	One record per game. Holds the board as a 361-character string (. empty, B black, W white).
Connect_Six_Move__e	Platform event published after every change, so open boards refresh.
ConnectSixController	Game engine: create, join, place a stone, resign. Checks every rule on the server.
ConnectSixControllerTest	Apex tests (needed for code coverage when you promote a version).
connectSix (LWC)	Lobby and board UI. Uses lightning/empApi for live updates.
Connect_Six tab	Holds the connectSix component.
Connect_Six app	Standalone Lightning app containing the tab. This is what players open from the App Launcher.
Connect_Six_Player permission set	Read-only access to games, plus access to the controller, event, tab and app.

Why the controller runs without sharing

Game records are read-only for players, which stops anyone from editing a board by hand. Every change goes through ConnectSixController. The controller checks that the caller is a player in the game, that it's their turn, and that the move is legal before it writes anything.
