AI Roblox game generator
Describe a game, watch it take shape and keep refining it in chat. Export your work to Roblox Studio when you are ready to playtest.
PromptBlox turns a game description into a Roblox build you can develop further. Start with the world you imagine and what players should do there. The AI can author the scene and gameplay scripts, while you guide the result through chat.
Creation starts in your browser. You can review the world, request changes and download a .rbxlx place file with its saved scene and scripts. Roblox Studio is the next step for playing the game, making detailed edits and publishing to Roblox.
From your first message to a Roblox build
Describe the world and the game
Open Create and write your idea in the chat box. Include a setting, a player goal, the main activity and the look you want. Choose an available build level, check your account usage and send your prompt to start.
Follow one concept into the live workspace
PromptBlox generates one concept image to guide the build. The centered chat opens into a workspace with build activity and a 3D preview as scene updates arrive. Look at the layout, routes, colors and landmarks as the world takes shape.
You can send notes in chat while the build runs. When it finishes, describe one focused change at a time and follow the progress updates to see when it has been applied.
Refine the same game
Continue in the saved game’s chat to improve a specific area or mechanic. For example: “Widen the bridge beside the post office and make the delivery sign easier to see. Keep the house layout and colors.”
After a playtest, describe what happened and what you expected. “The parcel disappears when I collect it, but my delivery count stays at zero” gives the next edit a concrete problem to address.
Export, playtest and publish in Studio
When the version is ready to test, open Export and download its .rbxlx file. Open it in Roblox Studio and play the full loop: arrive, start the activity, succeed or fail, and try again. Check the controls and any multiplayer interactions too.
Follow Roblox’s testing guide and publishing instructions when you are ready to bring in players.
Start with an idea you can test
These example prompts show how to combine a setting with a small gameplay loop. Use them to write your own prompt, then review and playtest the generated result.
A treetop delivery game
Make a small treetop village where players collect a parcel from the post office and deliver it to a marked house. Connect the houses with broad wooden bridges. Show the delivery goal and reward, then let the player take another parcel. Use warm wood, green leaves and bright route signs.
A tidepool collecting game
Make a sunny tidepool cove where players collect shells and bring them to a beach kiosk. Show how many shells they are carrying and let them trade shells for a basket upgrade. Keep the first version to one cove with a clear route back to the kiosk.
A short sky-island obby
Make a beginner sky-island obby with wide grass platforms, stone arches and a visible finish tower. Add checkpoints between sections, return players to their latest checkpoint after a fall, and give them a restart option at the finish. Use normal Roblox jumping.
Plan your first build
Start with the smallest version that expresses your idea, then expand after you have played it. Check plans and usage for current options. Build level, scope and follow-up changes affect the allowance you use and the time the work takes.
Questions about AI Roblox generation
What does an AI Roblox game generator create?
PromptBlox can author a Roblox scene and Luau gameplay scripts from your description. You review the scene in the browser, request changes in chat and export the saved version as a .rbxlx place file. Playtest the result in Roblox Studio before sharing it with players.
How does the concept guide my game?
PromptBlox generates one concept image from your message and uses it as a visual reference while the build continues. Describe the setting, colors and main structures you want in your starting prompt, then follow how they take shape in the workspace.
Can I change a game I have already generated?
Yes. Open the saved game and continue in its chat. Name the area or mechanic to change, explain the result you want and identify anything you want to keep. Review the updated version and playtest any gameplay changes in Studio.
Can I play the game in the browser preview?
The browser viewer is for reviewing the scene and its appearance. Use Roblox Studio to test avatar movement, collisions, scripts and multiplayer behavior.
How much does generation cost, and how long does it take?
Check the available usage in your account and the current pricing page before starting. Time and usage depend on the build level, the scope of your game and the changes it needs. Allow time for playtesting and improvements as your game develops.
