four-in-a-row

Four in a Row is a local two-player Poe app for the classic public-domain connection game. Players alternate dropping red and yellow discs into a 7-column, 6-row board; the first player to connect four vertically, horizontally, or diagonally wins. If the board fills without a connection, the round ends in a draw.

The app uses synced-store for persistent round state and a Three.js scene for the main board and pieces. It is designed for compact Poe iframes, including very small phone-shaped viewports.
