About

A single-file, offline Gungi (軍儀) game. The rules are a faithful port of gungi.js v3.4.11, the open-source engine behind gungi.io, verified move-for-move against it (7,000+ positions in the saved runs, over 1 million generated moves, including tower captures, leaps and betrayals). Bots and engine are plain JavaScript; the stronger bots run in a Web Worker so the board never freezes.

Bot levels: 1 Hunter Exam (random) · 2 Rookie Hunter (greedy) · 3 Royal Guard (alpha-beta depth 2 + quiescence) · 4 Netero (iterative deepening, TT, ~1.5 s) · 5 Meruem (same, ~5 s) · 6 Komugi (stronger search and evaluation, ~5 s).

Phone tip: the game is a single HTML file and needs a real browser tab. On iPhone, chat and Files previews show the layout but do not run JavaScript, so the board stays empty — use Share → Open in Safari. On Android, open the file in Chrome.
