tapatan

Tapatan is a local two-player Poe app for the Filipino three-stone alignment game. Players place three black and white stones on a 3 by 3 line board; if nobody wins during placement, they slide stones one step along a marked line into an empty point until someone makes a row.

The app uses synced-store for persistent round state and a Three.js scene for the board, animated stones, selected-piece markers, legal-slide highlights, and winning-line highlights. It is tuned for compact Poe iframes and very small phone-shaped viewports.
