Impostor Game (offline)

What is it?

Role-based impostor-style game for mobile, 100% in the browser with no backend. Uses localStorage so a reload doesn't lose the match. Features impostor-specific words for each civilian word to make the game more challenging!

Structure

• index.html: main UI.
• styles.css: mobile-first, no-scroll optimized styles.
• script.js: game logic (roles, timers, voting, tiebreaks, word pools with impostor variants).
• word-pools/: 22 word pools in .txt + manifest.json.

Available pools (22 total)

Key rules

• Defaults: up to 10 players; impostors by player count (<=5 →1, 6-7 →2, >7 →3) and never more than half.
• Time defaults: 5 min with 4 or fewer players, up to 15 min with 10; deliberation = 1/3 (rounded).
• No self-voting. Max executions = number of impostors.
• Tie on execution slots: 1 extra minute of deliberation and a new vote only among tied players; if tie persists, impostors win.
• Starting player and direction (clockwise/counter-clockwise) are random.

How to run (offline)

Use any static file server so fetch can read the .txt files (needed if opening via file://). Example with Python:

git clone https://git.dariosevilla.es/dasemu/web-imposter-game
cd web-imposter-game
python -m http.server 8000

Open in browser: http://localhost:8000

Word format with impostor variants

Each word pair consists of:

• Civilian word: What most players see
• Impostor word: A related but different word that impostors see

Example from animales_naturaleza.txt:

Oso|Pez
Camello|Arena
Elefante|Safari

This makes the game more interesting as impostors have a related word to work with!

Add new pools

1. Create a .txt in word-pools/ with optional header # Name and pairs civilian|impostor per line.
2. Add an entry in word-pools/manifest.json with id, name, emoji, count, and optionally local: true.
3. (Optional) To make it work offline, add an embedded version in script.js EMBEDDED_POOLS array.

Notes

• State is saved in localStorage (impostorGameStateV2). Use "New match" to clear it.
• Mobile optimized: No scrolling required on setup screen, reveal via swipe or tap, compact adaptive UI.
• Pool selection grid has vertical scroll when needed to fit all 22 categories.
