# How to Write a Good Roblox Game Prompt

Describe the world, what players do, and how the game responds. A clear first request makes the result easier to build, test, and improve.

## Begin with one sentence

Start with the game you want to play: “A floating-island adventure where players restore an ancient observatory.” This gives the world a purpose. You can describe an original genre or a mix of ideas; there is no required preset to select.

Then explain the details that matter most. There is no magic word count. A short, complete request is more useful than a long list of conflicting features, but a complex idea may need several organized paragraphs.

## Describe five things

### The world

Name the setting, architecture, materials, lighting, and main landmark. “Sunset islands with white-marble ruins and a glowing willow tree” gives more direction than “an epic fantasy map.”

### The player loop

Explain the action, feedback, reward, and next step. For example: collect crystals, see them added to a small inventory, use them to power a beacon, then unlock the next bridge.

### The layout

Describe relationships between places. Put the arrival dock near the first objective, connect the islands with usable bridges, and make the final landmark visible from spawn. State whether a vehicle must fit through a road or doorway.

### The controls and interface

Say which actions need keyboard, mouse, and touch input. Ask for readable interaction prompts and a compact HUD. On mobile, important controls should leave room for movement and the camera.

### The first-version priorities

Tell PromptBlox what must work now and what can wait. A complete collection quest is a clearer first milestone than quests, trading, pets, racing, and a large economy all at once.

## Turn a loose idea into a build request

“Make a huge fantasy game” leaves the architecture, activity, and finish undefined. Here is a more useful version:

```text
Build a sunset fantasy archipelago with one central island and two smaller islands. The central landmark is a massive bioluminescent willow tree surrounded by glowing crystals and ancient white-marble ruins. Use broad stone bridges, planted terraces, and an observatory visible from the arrival dock.

Players collect three crystals from the connected islands and place them in sockets around the willow. Each crystal lights one branch. When all three are placed, open the observatory and show a completion message with a restart option.

Keep every objective reachable from spawn. Add safe checkpoints for falls, clear feedback when a crystal is collected, and a compact progress display. Support keyboard and touch interactions. Prioritize this complete quest and the main architecture; leave combat and trading for later.
```

The example is a request you can adapt, not a guarantee of a particular result. Playtest the generated game and refine the parts that need work.

## Use images for visual direction

When you provide a reference image, say which features matter: the silhouette, material palette, landmark arrangement, or atmosphere. Also describe the gameplay, because a picture cannot show every interaction or rule.

A concept image is visual guidance. The generated world and an actual gameplay screenshot are different artifacts. Compare your result at player height as well as from above.

## Refine with an observed problem

After testing, identify the location, what happened, what should happen, and what should stay the same. Give one coherent change at a time so you can evaluate it.

```text
At the bridge between the arrival dock and crystal garden, my character catches on the raised join. Make that crossing continuous and walkable in both directions. Preserve the bridge style, island positions, quest items, and existing progress logic. Keep the railing outside the walking path.
```

Refinements use your available allowance. Check the result before spending more on unrelated details.

## Check the prompt before building

- Can a new player tell what to do first?
- Is there a finish, reward, or repeatable next action?
- Do all required locations connect?
- Are the important interactions described, rather than only their appearance?
- Have you said what must work on touch devices?
- Can extra features wait until the first loop is tested?

Open [Create](/create) when the request is ready. If the result needs a repair, use the [refinement guide](/guides/fix-broken-game) to turn the issue into a precise follow-up.
