LineDrawing3D, a maze and puzzle game merged by Claude Code

Claude Code wrote a line-drawing puzzle game and a Doom-like maze in the Ring language with RayLib, then merged them into one game in about eight hours.

The full story

The developer asked Claude Code for a puzzle game whose solutions are based on drawing lines, then for a Doom-like game, and then asked it to merge the two so the puzzles sit inside the maze. Finally it added collectible spheres and quotes.

The game is written in the Ring programming language with RayLib, took about eight hours, and the developer says the code is entirely prompt-generated. Their lesson: build components as separate, testable pieces and have Claude merge them.

What this is. Real projects where people used Claude to build, fix, port, revive or take apart something, from jailbroken Kindles to rebuilt DOS games, plus the times it went badly wrong. Every build links to where it was shared, and every source is listed here.

How far to trust it. We summarise what people reported and say what each build rests on: a full write-up with code, a short post, or a passing comment. We haven't tested them ourselves. Photos are shown from the original sources with credit. Only modify hardware you own, and back up first.

Privacy. No accounts. Analytics cookies (Google Analytics) only if you accept them; no ads or cross-site tracking. Searches are counted anonymously (just the words) to show what's popular, and so are clicks on Ask Claude (just the count).
