Then specify the gameplay or behavior, concrete details, constraints, and how you will check the result. There is no universal prompt template: Google DeepMind’s Genie, Roblox Build, and Roblox Studio Assistant support different workflows.
First, choose the kind of output you want
“AI game generator” can mean several things. A world generator creates an environment to explore; a game generator turns a description into a basic playable starting point; a project assistant edits objects or scripts in an existing game. An asset generator focuses on a model or other component. Before writing, decide which output you need and what the tool can actually produce.
| Workflow | What to describe | Useful iteration |
|---|---|---|
| Explorable world, such as Google DeepMind’s experimental Project Genie | Environment, character, movement, interaction with the world, and mood | Inspect and revise the preview sketch; use an image or remix where supported |
| Basic playable game, such as Roblox Build | Game form, core loop, controls, challenge, goal, and visual direction | Request one specific change after generation |
| Existing project edits, scripts, or assets, such as Roblox Studio Assistant | Named object or asset, desired behavior, trigger, boundaries, and a test | Plan, implement a small step, playtest, then refine |
The tools do not have identical inputs or scope. Genie’s guide describes text and image prompting and preview-sketch iteration. Roblox says Build focuses on 2D and 2.5D games and works best with simpler forms. Studio Assistant works with project context to help modify objects and scripts. See the respective guides: Google DeepMind’s Genie prompting guide, Roblox Build documentation, and Roblox Assistant documentation.
For an explorable world, separate the setting from the character
Describe the environment and the player character distinctly. This helps make the scene, movement, and interaction legible rather than burying them in one block of atmosphere. Google DeepMind advises direct, action-oriented descriptions: “Keep your descriptions to-the-point. Short declarative sentences work well.”
#1 Best Overall
- Environment: Name the place, terrain, surfaces, lighting, style, structures, objects, weather, and visible motion.
- Character: Describe appearance, identity, capabilities, and how it moves.
- Interaction: Say what movement or action visibly changes: footprints, splashes, cut grass, moved objects, or another clear effect.
- Mood: Add sensory details such as light, sound, texture, or atmosphere once the environment and action are clear.
Adaptable example, not a tested prompt: “Environment: A compact island with black volcanic sand, wind-bent palms, and a ruined lighthouse at the north end. Dawn light and low sea mist. Waves push loose driftwood across the beach. Character: A small brass diving robot that walks slowly and leaves wet footprints. It can pick up driftwood and place it beside the lighthouse.”
If the tool offers a sketch preview, inspect it and make a targeted change rather than replacing the whole prompt. Genie’s guide also describes image uploads, sketch modification, and remixing prior worlds; these options can help when a visual reference is more precise than additional prose.
For a playable game, define the loop, controls, and goal
Start with what the player repeatedly does and how that action produces progress. Roblox Build’s examples include collecting coins and buying upgrades in a clicker, and dodging obstacles while collecting power-ups in a side-scroller. Its guidance is apt: “The best results come from clear, specific descriptions.”
- Game form: Identify a manageable type, such as a clicker, arcade dodger, collect-and-score game, side-scroller, or puzzle.
- Core loop: State the repeated action and reward or progress that follows.
- Controls and challenge: Explain what input does, what blocks progress, and what failure means.
- Goal: Give a score target, level endpoint, unlock, or other win condition.
- Presentation: Specify setting, character, visual style, and sound if the tool supports them.
- Scope: Ask for a small first version, such as one short level, before adding secondary systems.
Adaptable example, not a tested prompt: “Make a 2D side-scrolling game about a courier crossing a rainy city. The player moves left and right and jumps over puddles and barriers, collecting three parcels per level. Show the parcel count and a finish gate. Use a bright comic-book look with high-contrast silhouettes. Start with one short level.”
Recommended Free Tools
Roblox Build currently documents a focus on 2D and 2.5D and simpler game types. A prompt for a sprawling 3D multiplayer world is a poor fit for that stated scope; reduce it to a supported, testable slice or choose a tool designed for the output you want. Roblox’s July 2026 announcement describes Build as a way to turn text prompts into a basic game starting point for iteration, playtesting, sharing, or publication—not a guarantee of a finished game. Read the Roblox announcement.
For a project assistant, name the object and set boundaries
When editing an existing game, anchor the prompt in something the assistant can identify. Give the object’s project name where possible, what should happen, the trigger, what must remain unchanged, and how you will verify the edit.
Adaptable example, not a tested prompt: “On the part named CheckpointPad, add behavior so touching it saves the player’s current checkpoint. Do not change the part’s size or material. Show a short confirmation message when the checkpoint is saved. Tell me which script you changed and what I should test in play mode.”
For a larger task, ask for a plan first, review it, and implement one small part at a time. Roblox’s Assistant development guidance recommends a Plan > Build > Playtest > Refine workflow: establish the core world and gameplay before layering on systems such as UI, scoring, or win/lose conditions. This makes it easier to spot which change caused an unwanted result.
When prompting for a model or other asset
Describe the asset itself rather than an irrelevant background. Include its important shape, material, color, age, and distinguishing features. If it should scale or adapt to a changing number of parts, name the properties that should remain editable and explain how the asset should respond.
When image references are supported, Roblox’s prompt guide recommends a PNG with good lighting, a clear subject, a simple background, and, where practical, a useful three-quarter or isometric view. A clean reference helps communicate form; it does not remove the need to inspect the generated model.

If the result is too broad, add mechanics, objects, or constraints—not a pile of extra mood adjectives. If one detail is wrong, request a targeted change. Roblox Build gives examples such as making coins larger or adding a timer. For an assistant that edited the wrong thing, identify the project object by name and restate what must not change.
- Review the output: Check whether the main action, setting, controls, and goal match the request.
- Choose the biggest mismatch: Avoid changing several unrelated elements at once.
- Make a bounded follow-up: State the exact edit and preserve the parts that already work.
- Playtest or inspect again: Confirm the change improved the result without breaking another part.
- Expand only after the basic slice works: Add secondary systems in separate steps.
Do not assume repeated prompts produce identical results. Roblox’s prompt guide says, “Many AI tools are non-deterministic, meaning they don’t create the exact same output each time you ask them to do something.” Its Assistant tutorial also notes, “There is more than one right way to make any particular request, but every word counts.” Try a small wording change when a result is off, and review generated scripts and behavior in play mode rather than treating them as correct by default. See the Roblox Assistant tutorial and Roblox Assistant prompt guide.

Check tool constraints and player-facing requirements
Prompt quality cannot overcome a tool’s documented limits. Roblox Build’s supported scope is currently described as 2D and 2.5D, with simpler game types working best. Roblox also says some requests can be refused or reframed because of content rules, account age settings, or copyright and intellectual-property restrictions. If the request is blocked, simplify or reframe it within those constraints rather than trying to evade them.
If a Roblox experience includes player interactions that trigger AI responses, Roblox’s generative-AI policy requires creators to disclose that in the Content Maturity questionnaire. The policy also requires AI integrations to follow Community Standards and provide transparency; extended AI interactions have additional Restricted-label requirements for audiences under 18. Check the current Roblox generative-AI policy and experience guidelines before publishing.
