Free means playable
Ten guest turns with no account, then daily free Candles — enough to keep a life moving every day without paying.
Free to start
Free AI Game — Play in Your Browser, No Sign-Up
No install, no account wall, no deck of paywalled features up front. Open a world, become someone in it, and take your first ten turns free — the world starts reacting immediately.
For anyone searching for a free AI game that is more than a chatbot: a persistent life sim you can start in seconds on desktop or mobile.
Most "free AI games" are either thin chatbot wrappers or demos that stop the moment the story gets interesting. Altworld's free path is real play: 10 guest turns with no sign-up, in the same simulation paying players use — structured world state, NPCs with memory, factions, rumors, maps, and consequences that persist.
If you keep playing, a free account saves your runs and grants daily Candles — the in-game currency that fuels turns. There are optional top-ups and passes for heavy players, but nothing about the core game is locked behind them: same worlds, same engine, same freedom to attempt anything you can type.
It runs entirely in the browser on desktop and mobile. Lite mode resolves turns in seconds for chat-style play on the go; Full mode runs the deep simulation for long campaigns. Start with a curated life — a medieval villager before winter, a smuggler in a drowned city, an operator on a failing orbital relay — or browse community worlds and jump into someone else's timeline.
Browser-only, mobile-ready
Nothing to download. Lite mode is built for phones and resolves turns in seconds; Full mode runs the deep simulation.
Not a demo world
Guests play the real engine: persistent state, NPC memory, factions, rumors, and maps from the very first turn.

Is Altworld really free?
Yes. Your first 10 turns need no account at all, and free accounts receive daily Candles that fuel continued play. Optional top-ups and passes exist for longer sessions.
Do I need to download anything?
No. Altworld runs entirely in the browser on desktop and mobile — open the site and start a run.
What kind of AI game is it?
A persistent life simulation and story sandbox: you act in plain language and the engine updates a structured world — factions, rumors, economy, relationships — before narrating the result.
Can I play with friends for free?
Yes. Multiplayer sessions let friends join your world with an invite link and share the same persistent timeline.
