Ask for it like this

Copy this prompt, paste it into Claude or ChatGPT, and that's it. It's the short version: the minimum for the game to come out playable.

Hazme un juego de reventar globos con dardos para navegador, al estilo de los puzzles de dardos clásicos, con arte original.

- Un personaje fijo lanza dardos: arrastro hacia atrás para apuntar, la fuerza depende de cuánto estiro y el dardo vuela en parábola. Solo se ve el comienzo de la trayectoria.
- Cada dardo atraviesa varios globos. Tengo dardos contados por nivel y gano si reviento todos.
- Muros de madera que frenan el dardo y muros de goma donde rebota, para llegar a zonas escondidas. Más adelante, globos de metal, globos bomba, portales y cosas que se mueven.
- 40 niveles de dificultad creciente, y cada uno se tiene que poder ganar.
- Controles: arrastrar con el mouse o con el dedo.
Técnico: un solo archivo HTML con el CSS y el JavaScript dentro, sin librerías ni imágenes externas, todo dibujado en canvas. Que llene la ventana y se juegue con el dedo en el celular y con mouse en la PC.

This one is still in Spanish. Paste it as is (the AI understands it) and add "Answer in English" at the end.

Getting it as an HTML file

A game like this is a single file you open with a double click. These four steps are the same in any AI.

1. 1. Ask for the whole file

   Add this line at the end of your prompt: Give me a single, complete HTML file, nothing cut out, ready to save as index.html and open in the browser. Without it, you often get the code in pieces.

2. 2. Copy all of the code

   In Claude the game shows up on the side, already running, with a button to copy or download it. In ChatGPT, copy the whole code block: it has to start with <!DOCTYPE html> and end with </html>.

3. 3. Save it as index.html

   Paste it into Notepad (Windows) or TextEdit in plain text mode (Mac) and save it as index.html. Watch out for .txt: if the file ends up as index.html.txt, it won't open as a page.

4. 4. Double-click to open it

   It opens in your browser and it's ready to play, with nothing to install and no internet needed. To share it, upload it to any web host or send it by email: it's just one file.

If the game shows up blank, go back to the AI and paste the error from the browser console (right click → Inspect → Console). With that text it fixes it fast.

The full prompt, the one actually used

Longer and more specific: numbers, screens and style details. It's the one that produced exactly this game, unedited. Use it if you want to fine-tune the result.

Diego wrote it in Spanish and it stays in Spanish on purpose: it's the honest record of how the game was made, and a translation would be a prompt nobody used. Claude and ChatGPT understand it as is; add "Answer in English" if you want the game's text in English.

usa otro agente para hacer un  juego como baloons igual con leaderboard pero sin multiplayer

el que era como dardo o flecha que se tira como parabolas y tambien avveces habian niveles donde rebotaban en paredes o muros para alcanzar otras zonas ..

For ChatGPT, add the line from step 1 at the end: it tends to hand over the code in pieces.

What this prompt was missing

What became clear once the game was finished. If you're making your own from this one, add these from the start: fixing things later costs another round.

• Say how many levels there are and how difficulty ramps up: "like Bloons" doesn't say whether it's 10 or 100, or what shows up in each stage.
• Ask for every level to ship with a saved shot that beats it and a test that simulates it: without that, an impossible level goes live and nobody notices.
• Say what counts for the leaderboard in a level-based game (here: the campaign from level 1, with 3 lives). If you don't, each version invents its own rule.

What was asked after the first result, in Diego's own words (Spanish):

• La segunda línea del prompt es la respuesta a "¿cuál de los Bloons?": el clásico de puzzle con dardos, no el de defensa de torres.
• Como los demás juegos con ranking, al agente se le pasó además el estándar del sitio (ranking arcade, bandera de idioma, guardado por la página) y la exigencia de demostrar con pruebas que cada nivel se puede ganar.

It works in any AI

Claude, ChatGPT, Gemini, Copilot: the prompt is the same and so is the method. What changes is where you see the result. Four things that hold in all of them:

1. Ask for a single file

   "A single HTML file with everything inside, no libraries or CDN." That way the game works with a double click, with nothing to install, and you can upload it to any website.

2. Ask it to tell you what it assumed

   End with: "before writing the code, tell me in 5 lines what you assumed". That's where the gaps in your prompt show up, while fixing them is still cheap.

3. One fix per message

   Say what happens and what you expected. If you ask for three changes at once, one usually undoes another.

4. Ask it to test, not to promise

   "Check that every level can be won and tell me how you checked." That's how the games on this page found their bugs before going live.
