brandubh

Brandubh is a local two-player Poe app for a compact 7x7 Tafl-style board game. Attackers move first and try to capture the king. Defenders try to escort the king from the center throne to any corner.

This package implements a modern Irish Brandubh ruleset: one king and four defenders face eight attackers in a cross-shaped opening layout, pieces move any open distance orthogonally, only the king may stop on the corner escape squares or center throne, ordinary pieces are captured by sandwiching them between allied pieces or a hostile corner/throne, and the king is captured like an ordinary piece except on the throne, where attackers must occupy all four cardinal points. The in-app help reflects these exact rules.

The app uses synced-store for persistent turn state and a Three.js board with touch-sized square targets, selected-piece highlights, legal-target markers, last-move feedback, capture pulses, match scoring, and a compact help overlay. It is tuned for Poe iframes, including a 300 by 500 phone-shaped viewport.
