Prompt workflow
From text prompt to playable game
Describe the player goal, controls, obstacle, art direction, and feedback. OpenGame turns that brief into a browser-playable draft you can test and revise in Studio.
Why it works
Turn your idea into a playable game
A prompt you can test
Try: “Make a top-down delivery game. Move with WASD, collect three parcels, avoid moving bikes, and reach the depot in 60 seconds. Show a score and a restart button.”
A precise revision
After playing, ask: “Keep the map and controls. Slow the bikes by 20%, highlight the depot, and show how many parcels are still missing.” Change one issue at a time.
Reviewable artifacts
Capture preview links, version notes, and export files so the best draft is easy to revisit.
Workflow
A compact process for building browser-game drafts
Describe the smallest loop
Use one sentence for the player action and one sentence for the win/fail condition.
Add visual and camera rules
Specify side-view, top-down, runner, or 3D framing plus palette and UI mood.
Generate a first draft
Sign in to Studio, review the game brief and required Studio Credits, then generate one draft. Test it before adding more systems.
Tighten one issue per pass
Revise controls, pacing, readability, or reward feedback instead of rewriting the whole concept.
Keep the first run scoped to one core loop.
Review first frame, controls, and win/fail feedback.
Share a browser build before polishing assets.

FAQ
Fast answers before you build
Can I generate a game from only text?
Yes. A focused text prompt is enough for a first playable draft when it includes genre, controls, goal, fail state, and style constraints.
What should I avoid in the prompt?
Avoid asking for several games at once. Mixed genres and vague style words usually create weaker first drafts.
Can I use this for HTML5 games?
Yes. Preview the generated browser game in Studio, download the available HTML or bundle artifact, then test the exported version in your target browser.
Is custom generation free or available without an account?
Custom generation takes place in Studio after sign-in and uses Studio Credits. Check the current pricing and the cost shown before starting a run. Public game examples can be played before you create a game.
Write one prompt and test the result
Start with a short brief, play the generated draft, and iterate only after the core loop is visible.
