Prompt to game: how one sentence becomes something you can play

Write a single sentence and Tyrbo turns it into a game that runs on your phone. Between the prompt and the game sit a few questions, a plan you approve, and a build made from tested parts. This page explains each stage, and what to put in a prompt so the first plan is close to what you had in mind.

What happens to your prompt

Your prompt is the seed, not the spec. Here is the path it takes:

Reading. Tyrbo works out the genre, the core action, the threat and the goal from your words.
Questions. Anything unclear comes back as a short question with a guess already selected.
The plan. A title, a pitch, every part of the game, and concept art for the look.
The build. Tested bricks and map recipes, new code where your idea is unusual, art in your style, then checks on a low-end Android phone.
Play. You scan a code and it opens on your phone.

What to put in a game prompt

A strong prompt answers three things in one breath:

The verb: what the player does. Swing, stack, steer, match, dodge.
The pressure: what pushes back. Rising water, a chasing wolf, a ticking oven.
The goal: what success is. Reach the top, serve every order, survive the night.

Then add one flavor detail if you have it, like a setting or a mood: a sunken city, a cozy bakery, a neon highway. That gives Tyrbo enough to choose a style and build a world. The full guide on how to write a game prompt has more examples.

What to leave out of the prompt

You do not need to mention engines, programming languages, frame rates, physics settings or screen sizes. Tyrbo decides those, and it checks the result on real low-end hardware.

You also do not need to cram every feature in. A prompt with fifteen features tends to produce a plan that tries to do everything. Start with the core, approve a focused plan, then add features by talking once you can play it. Each one lands on the game you already have.

Prompts that work, and why

Compare two prompts. A fun space game gives very little to go on, so Tyrbo has to ask about almost everything. A tiny ship dodges falling satellites and grabs fuel cans to stay in orbit gives a verb, a pressure and a goal, so the questions are few and the plan is sharp.

Another good one: a bakery match-3 where clearing frosting tiles fills orders before the shop closes. It names the genre, the theme and the level goal. If you would rather type freely and see what comes back, the AI game generator page describes everything a prompt produces, and text to game covers what words can change after that.

Describe it
One sentence is enough. Say what you tap, what you dodge, what you win.
2
Answer a few questions
Each comes with our best guess picked, so most of the time you just tap Continue.

See the plan
A title, a pitch, every part of the game, and concept art, before anything is built.

Questions people ask

How long should a game prompt be?

One sentence is enough. Say what the player does, what makes it hard and what winning means. Tyrbo asks about anything important you leave out, and suggests an answer for each.

What if my prompt is vague?

That works too, it just means more questions. Each one comes with a best guess, so you can tap through quickly or take the chance to shape the game. A vague prompt plus good answers ends up in the same place.

Can I change the game after the prompt?

Yes. The prompt only starts things. After the game is built, you keep shaping it by describing changes, and you can ask for testing tools inside the game to tune it.

Does the same prompt always make the same game?

Your answers to the questions and your approval of the plan decide what gets built, so the game follows your choices, not chance. Two people with the same prompt can end up with different games.
