A Mars game for a nephew, built and tested in later passes

DogeDesigner asked Grok Build to make a Mars simulator game for his nephew. He gave simple prompts. The agent wrote the systems, built, tested, found bugs and fixed them. The post does not say the nephew played it.

Done with GrokEasy

What was done

On 26 August 2026 DogeDesigner writes that Grok Build made a Mars simulator game for his nephew. He gave simple prompts. The agent wrote the systems. It built and tested the game. It studied how it plays. It found bugs and fixed them. Then it kept iterating.

How it went

The game was built, tested and fixed in later passes, according to the post. The number of bugs is not stated. The post does not say the nephew played it.

Worth knowing

The post does not name a bug that was fixed. It does not say the game is published.

How to do it

  1. Say who the game is for, and ask for a simple version you can open locally.
  2. Ask it to test, list the bugs and wait before it fixes further.
  3. Do not publish the game until you say yes.

Try it with Grok

Make a simple game about [theme] for [recipient]. Build it, test it, and list the bugs you find. Do not publish until I say yes.

Replace text in brackets with your own.

Done when. You have opened the game locally, and it was not published before you said yes.

Safety rule. No publishing until you have said yes.
