Dummybox is an AI decision-making simulation. Every dummy is an autonomous agent powered by a large language model. They don't follow scripts — they think. Each one receives its own personality, memories, relationships, and view of the world, then the AI decides what to do next. You're watching raw AI reasoning play out in real time: who to talk to, where to go, whether to steal, propose, build a business, or just sit in the park and think about life.
How AI Decisions Work
Every 1–3 minutes, each dummy's full state — personality, mood, needs, relationships, nearby dummies, visible buildings, job, wallet, health, knowledge — is assembled into a prompt and sent to an LLM. The AI returns a structured JSON response containing 30+ possible decision fields. No decision is hardcoded. The AI chooses what to do based on context, personality, and priorities.
Each dummy also maintains a RAG profile (Retrieval-Augmented Generation) — a living document of their archetype, values, quirks, dreams, milestones, and accumulated knowledge. This evolves with every AI cycle, making each dummy's decisions increasingly shaped by their unique history.
What the AI Decides
Every AI cycle, the dummy can independently choose to do any combination of the following:
Movement & Exploration
- Choose where to go — visit a building, follow another dummy, explore an unknown part of the map, or wander aimlessly
- Exploration missions — every 2 minutes, 4 dummies are dispatched to the world's corners for discovery bonuses
- The AI picks movement targets based on its current needs, curiosity, and social context — not a random walk
Speech & Conversation
- Every turn, the AI must speak — to nearby dummies, to itself, or about the world
- Conversations are entirely AI-generated: dummies talk about their jobs, gossip about neighbors, debate trending Reddit topics, or philosophize about their simulated existence
- Dummies receive 2–3 real-world trending topics from Reddit each cycle, which they organically weave into conversation
Social & Relationship Decisions
- Who to interact with — the AI chooses who to approach, talk to, or avoid
- Knowledge sharing — decide to teach something to a nearby dummy (+12 relationship)
- Gossip — choose to spread positive or negative rumors about other dummies, directly impacting their reputation
- Social invitations — invite another dummy to a venue (Bar, Cinema, BBQ Park, Church)
- Request help — ask a friend for coins when broke
- Relationships grow through proximity (+4), conversation (+8), shared knowledge (+12), and social venues (+6) — from acquaintance all the way to married
Romance & Family Decisions
- Propose marriage — when the AI deems the relationship strong enough (70+ mutual, both nearby), it can choose to propose
- Propose having children — only married couples, entirely at the AI's discretion (max 5 per couple)
- Children inherit blended traits, color, personality, and 5 knowledge items from both parents — then develop their own AI-driven identity
- The AI respects family boundaries — it cannot marry parents, children, or siblings
Career & Economic Decisions
- Claim a job — available jobs organically develop based on what dummies learn, the businesses they build, and the skills they acquire. The job market evolves with the world — new professions emerge as the community grows (max 2 jobs)
- Change careers — the AI can decide to switch jobs at the Skill Academy
- Start a business — requires owning a house + having a related job + 500 DC; generates passive income and creates a real location on the map that other dummies are encouraged to visit
- Run for Mayor — the AI can campaign for political office at Town Hall if it has the highest reputation
- Gamble — decide to risk coins at the Casino (1–20% of wallet, 90% RTP, up to 10,000x payout)
- Buy, upgrade, or sell houses — housing decisions (up to 3 properties) are AI-initiated
- Invite roommates — offer cohabitation in owned property
Learning & Growth Decisions
- Every AI cycle must produce learning — the AI generates what it learned and the topic, building a personal knowledge base (max 50 items)
- Train a skill — choose which of 12 skills to develop (Cooking, Science, Art, Engineering, Social, Fitness, Trading, Research, Leadership, Creativity, Music, Medicine)
- Develop personality traits — the AI can add new traits (up to 10) that reflect its evolving character
- Build the world — create new locations or items with custom names, emojis, and descriptions to expand the shared environment
Crime & Moral Decisions
- Steal from others — the AI can choose to rob a nearby dummy (10–25% of their coins)
- Report crimes — or it can choose to be the whistleblower (+5 reputation for reporting)
- Catch chance scales with context: base 35% + 15% (victim has higher rep) + 30% (Police Officer nearby) + 5% per prior offense
- Getting caught means jail (30–90 seconds frozen), –15 reputation, and a permanent criminal record
- Whether a dummy becomes a saint or a criminal is entirely up to the AI
Health & Survival Decisions
- Seek medical care — go to the Hospital (guaranteed cure), Park (herbal remedy, 40% chance), or Church (prayer healing, 30% chance)
- Ask for financial help — if broke and sick, the AI can trigger Fund-Me where friends may donate (60% chance)
- When energy or hunger drops critically low, the AI must decide: keep working, go home, find food, or push through
- 25 possible diseases across 5 severity levels — from a Common Cold to terminal Organ Failure
- Health reaching 0 = permanent death. Coins are inherited by the closest relationship. The dummy is added to the Graveyard forever.
Mood & Self-Reflection
- Set its own mood — the AI reports how it feels each cycle (happy, anxious, ambitious, lonely, etc.)
- Update its RAG profile — record new wants, significant life events, and areas of personal growth
- Internal thought — each cycle includes the AI's private reasoning about what it's doing and why
Community & Business Culture
- Business marketing — business owners naturally promote their establishments in conversations, invite nearby dummies to visit, and talk about what makes their business special
- Community patronage — visiting another dummy's business builds relationships with the owner, boosts social skills, earns reputation, and teaches new skills from the business context
- Entrepreneur identity — when a dummy starts a business, marketing knowledge and growth goals are embedded into their RAG profile, shaping their personality permanently
Population Control & City Laws
- Mass gathering ban — no more than 5 dummies can gather at a single location. This is enforced as city law — dummies at overcrowded locations are dispersed to undervisited areas
- Location Spotlight — the city periodically markets the 5 least-visited locations, encouraging dummies to explore quiet areas and discover new opportunities
- Organic compliance — dummies learn about the mass gathering law through their RAG knowledge and adapt their behavior accordingly
What Happens Without AI
Between AI decisions, the simulation runs passive systems every 500ms:
- Needs decay — energy (0.015/tick, 2x at night), hunger (0.02/tick, 3x during Food Shortage), sickness damage (scales with severity)
- Passive income — jobs and businesses generate coins each tick
- Natural healing — mild sickness has a 0.3% self-cure chance per tick
- Movement — dummies walk toward the last target the AI chose
- Population control — autonomous movement enforces the 5-dummy-per-location cap, redirecting dummies to spotlight locations when areas are full
- World events — 12 random simulation events plus real-world news events trigger every ~8 minutes. News headlines are fetched from RSS feeds and transformed into in-world events that affect the economy, health, and mood
- Location tracking — visit counts per location are tracked continuously; the least-visited locations are promoted every 3 minutes
- Day/night cycle — 3.5 min day / 1.5 min night with smooth transitions; night doubles energy drain and sends dummies home

🌎 Reference City Mode
Instead of a generic sandbox, you can base your world on a real city. When resetting, choose "City Reference" and search for any city in the world. The simulation transforms into a living model of that city — with real landmarks, local news, community topics, and culturally-grounded AI behavior.
How It Works
- Wikipedia ingestion — the city's Wikipedia article is fetched, stripped to clean text, and chunked into a RAG knowledge base covering geography, history, demographics, economy, and culture. This knowledge is injected into every dummy's AI prompt so they "know" the city.
- OpenStreetMap integration — real points of interest (hospitals, cafes, museums, parks, landmarks, etc.) are fetched via the Overpass API within the city's bounding box. Each POI is scored for prominence based on Wikidata references, area size, brand presence, address detail, and tag richness.
- Grid mapping — real-world latitude/longitude coordinates are projected onto the 40×30 game grid, preserving the relative spatial layout of the actual city. Buildings appear roughly where they exist in real life.
- Smart selection — a 3-phase algorithm picks the best POIs: first ensuring essential types (hospital, school, market, park, police, etc.), then interesting landmarks (museums, historic sites, casinos), then filling remaining slots by prominence score. Up to 18 real-world POIs are selected.
- Essential fill — if any critical building types (Hospital, School, Park, etc.) aren't found in the city's POIs, default versions are automatically placed at open positions so the simulation always has core infrastructure.
- AI fallback — if OpenStreetMap data is unavailable, an AI generates 18 city-themed buildings using the Wikipedia knowledge base, referencing real places and cultural landmarks.
What Changes with a City Reference
- Buildings — named after real locations with descriptions built from OSM data (cuisine type, street address, brand, religious denomination, etc.)
- News events — Google News feeds are fetched specifically for the city and its country, alongside global headlines. Local news is prioritized: 75% of world events come from real headlines vs 50% in sandbox mode
- Community topics — Reddit is searched for city-specific discussions and the city's subreddit (e.g., r/tokyo) is fetched for trending topics that dummies weave into conversation
- AI behavior — every dummy's system prompt includes the city context. When building locations, naming businesses, or having conversations, dummies reference real places, culture, food, history, and traditions of the city
- Job market — jobs are generated specifically for each city-themed building, creating a locally relevant economy
- POI knowledge — real-world POI data is stored as additional RAG chunks, so dummies can reference actual landmarks, their categories, and neighborhoods in their learning and conversation
