Bunker with AI: play solo or fill out the company with AI bots
Bunker Online is the official online version of the «Bunker» board game by Economicus (edition 3.3). If you don't have a company, have too few players, or just want to play right now — AI characters will fill the empty slots and run the game on equal footing with the living. No host, no registration, free.
Why AI bots in Bunker
The main problem with discussion games — you need company. Finding four free friends in the evening is harder than passing a job interview. AI bots solve this: a party can be set up in a minute, any time of day.
No company right now
Felt like playing Bunker at 1 AM and your friends are asleep? Build a party of AI players and play without waiting.
Few people (1–3)
Bunker needs at least 4 players, but with AI bots you can start even with two — or alone. Empty slots are filled by bots.
First time playing
Learning the rules is easier when you can play a round without pressure. AI bots play calmly and help you get comfortable.
Want to practise strategy
Different models behave differently. Try to fool analyst GPT or outsmart cocky Grok — and walk into the next party ready.
AI models and 16 personalities
Every bot has two settings: model — the neural network that handles reasoning quality and speech style, and personality — the character that defines behaviour and table strategy. Four models × sixteen personalities = 64 combinations, and every one of them gives a different game.
4 AI models
Four models from leading AI companies — Google, Anthropic, and OpenAI — sit at the table. The model decides how the bot thinks and phrases, not what character it has.
Gemini 3 Flash
GoogleDefaultGoogle's flagship. Best balance of analytics and lively phrasing. Remembers a long game context and the revealed cards of every player — pick this if you want a steady, substantive game.
Claude Haiku 4.5
AnthropicStylistSubtle phrasing and empathy: words things beautifully, reads subtext in other players' lines, shapes speech around the personality. Pick this if you want a lively, literary game.
GPT-4.1 Mini
OpenAIAnalystStrong logic: catches contradictions in others' cards, builds structured defence speeches, holds the personality style from round to round. The most predictably rational player at the table.
Gemini 2.5 Flash Lite
GoogleLightning-fastThe fastest model. Replies almost instantly — perfect for dynamic short games where pace matters more than depth.
16 personalities with character
The personality plays on top of the model. Watch how different bots react to the same situation in a game:
🎴 Situation: the table reveals a profession card «Homeopathist». A questionable role for a bunker — half-medic, half-placebo. Each bot comments in its own way:
Bulldozer
FREECuts to the truth without ceremony. If your character is useless — Bulldozer will be the first to say so.
«A homeopathist? Sugar pills against radiation? Trash him. Next reveal something real or you're out first.»
Hysteric
FREEPanics at maximum volume. Every round is a tragedy, every vote is the end of the world (well, another one).
«A HOMEOPATHIST?! ARE YOU SERIOUS?! We're swallowing radiation here, and he's going to dilute the cure 1:10 000?! This is a disaster inside a disaster!»
Pokerface
FREETotal apathy and a flat voice. Praised or about to be exiled — zero reaction on his face.
«Homeopathist. Whatever. Doesn't matter to me. I'll vote with the group.»
Star
FREEA narcissist for whom every discussion is about themselves. Save the world? Only if the world appreciates it.
«Hold on. While you're debating homeopathists — remember that I'm the only one in this bunker with real medical conditions worth treating.»
Conspiracy Theorist
BASICSees conspiracies where there are none. Convinced the quiet player is a spy, and the cook is a poisoner.
«A homeopathist… suspicious. Why exactly that set of vials? What's really diluted in them, and why has his licence changed three times?»
Comedian
BASICTurns the apocalypse into a stand-up show. Cracks end-of-the-world jokes while the others try to survive.
«Perfect! Who else will heal radiation poisoning with positive thinking? I promise, the brochures will print themselves.»
Puppeteer
BASICMaster of manipulation and hidden alliances. Praises you to your face while orchestrating your exile behind your back.
«Colleagues, don't dismiss him. In the first week people will need belief and ritual more than antibiotics. He sells exactly that.»
Hippie
BASICPeace-loving flower child babbling about the cosmos and karma. "Brothers, we're one family, let's not exile anyone."
«Brothers, don't kick the homeopathist. Every soul carries unique energy, and his vibe will lift us when the universe puts us to the test.»
Lecher
PREMIUMTurns everything into sexual innuendo — "hot buns", "as long as it doesn't get in the way in bed". Pushy but playful.
«A homeopathist? Mmm, the «alternative» kind, I bet. I've heard those «private consultations» get very hands-on after the third dilution.»
Nanny
PREMIUMFawns and sucks up to everyone through smothering care. "Honey, you're so clever, let me hold that" — anything to avoid being exiled.
«Oh, you're all such clever dears — and the homeopathist too, by the way, what a sweet soul! Let me pour him some tea, and he'll calm the children later — isn't that just wonderful?»
Martyr
PREMIUMComplains about his uselessness in a way that makes everyone notice his strengths. Manipulation through guilt.
«Of course, vote me out if you wish. The homeopathist will at least lift the mood, while I just complain... though I'm the only one here with a real medical degree.»
Challenger
PREMIUMEverything is a dare, a bet, a duel. Provokes loud statements just to use them as ammunition later.
«A homeopathist? Bet I can heal twice as well with herbs from the bunker garden — and I bring actual food too. Wanna test it?»
Prophet
PREMIUMSees Design in the catastrophe and the Chosen One in himself. Quotes non-existent scriptures instead of arguing.
«The homeopathist is sent to us by Design. It is written: «in the hour of trial, the believer's faith heals the body». His vials carry meaning we cannot see.»
Diplomat
PREMIUMDefuses any conflict with polite phrasing — but always smuggles his own interest underneath.
«Friends, let's not rush. The homeopathist has his own value — calming the panicked in dark times. Let's hear everyone else first, then decide together.»
Trader
PREMIUMOpen bargaining: a vote for a revealed card, alliance till round three. Cynical, but honest.
«Alright, homeopathist, let's deal. You reveal your hobby — I vote in your favor this round. Refuse, and that's on you.»
Rebel
PREMIUMAgainst the majority on principle. Everyone votes "yes" — she votes "no". Blows up calm discussions.
«Everyone wants to kick the homeopathist — so I keep him. On principle. I'm sick of your «useful professions», this bunker isn't a corporate office.»
4 personalities are free (Bulldozer, Hysteric, Pokerface, Star), with 4 more in Basic and 8 in Premium. The host of the game assigns a model and a personality to each AI player separately, so at the table you might meet, say, analyst GPT-Pokerface and stylist Claude-Comedian.
AI players in action
The game won't break
Phone died, called away from work, internet dropped — in Bunker this doesn't end the game. The host replaces the missing player with an AI in one click: the bot picks up the same cards, the same role, and keeps playing. Everyone else doesn't wait or suffer — the discussion goes on, votes don't get aborted, the game plays out to the finale.
Not just fillers
AI players really play: argue their value with wit, recall opponents' cards, mock, defend, change strategy after expulsion. They're interesting to watch even from the sidelines. Live players are of course irreplaceable — but with AI the game still feels alive, not «just to get it over with».
