The engine of solo play. Ask fate a question — and find out what happens next.
Solo tabletop RPG without a game master means one thing: you need something to answer your questions. Is the door locked? Does the guard recognise you? Does the ambush succeed? The Oracle answers — not with a simple coin flip, but with atmosphere, consequence, and story.
The Board Viking Oracle is a free AI-powered GM emulator. Ask any question about your current scene, add optional context to anchor the answer, and get a response that drives your story forward rather than just resolving a binary.
Here’s the Oracle in action. You’re sneaking into a warehouse at night. You ask a simple question:
Is the warehouse guarded?
No context — Oracle returns fragmentsYES — a lantern moving, second set of boots, the smell of tobacco, someone who isn’t supposed to be there
Four fragments. Not a full sentence. The Oracle hands you the raw material and you decide what it means. Is the guard on patrol or waiting? Is the tobacco smell important? That’s yours to interpret.
Now the same question with context:
Is the warehouse guarded?
ContextAbandoned dockside warehouse, I’m a hired thief, the merchant who hired me has connections to the city watch
Oracle returnsYES — but not the guard you expected. Two men in city watch uniforms who aren’t acting like city watch. They’re waiting for something. You’re not sure if you’re the something.
Same answer. Completely different story. Context transforms the Oracle from a word generator into a narrative co-pilot.
The Oracle has several question types, each suited to a different moment in play. For example:
The foundation of oracle play. Good for most questions — Is the door locked? Does she believe me? Do they have what I need? Add the Likely or Unlikely toggle to shift the odds without removing the surprise.
When you want the Oracle to describe what happens rather than just confirm it. For example, you don’t ask “is there an ambush?” — you ask “what happens when I step into the alley?” The Oracle gives you a narrative beat rather than a binary.
Drop something unexpected into a scene that’s going too smoothly. For example, you’ve picked the lock, the coast is clear, everything is going to plan — hit Complication and find out what just went wrong.
Plot Twist, Scene Interrupt, Revelation, Consequence, and Flashback unlock with a Viking subscription. Each is suited to a specific narrative moment — a Revelation surfaces a hidden truth, a Consequence delivers the price of your last action, a Flashback recontextualises what you thought you knew.
Every Yes/No question can be weighted. Likely means the yes result is more probable — use it when the odds are genuinely in your favour. Unlikely shifts the balance toward no. The modifier doesn’t eliminate the surprising answer; it just changes the odds, which is exactly how a real GM would adjudicate.
The Oracle speaks in twelve distinct tones — Neutral and Grim & Dark are free, ten more unlock with Jarl. The same question sounds completely different in Norse Saga versus Lovecraftian versus Cozy & Folkloric. Match your tone to your game and every answer arrives pre-loaded with the right atmosphere.
The Oracle is designed to work alongside any solo system — Ironsworn, Four Against Darkness, Mörk Borg, Shadowdark, Call of Cthulhu, D&D 5e. It doesn’t replace your game’s own resolution mechanics. It answers the questions your rules don’t cover — what the NPC is thinking, what fate has in store, what lurks in the part of the scene your dice haven’t touched yet.
