The full story

Kings vs Queens is an 8x8 logic puzzle where you place eight queens and two kings under strict rules, with a hint system that walks through each deduction. The whole game is one self-contained HTML file built through Claude.ai chat sessions, with no IDE, terminal or build tools.

The loop was: Claude writes the code, the maker downloads the file, playtests it on their phone, screenshots anything that feels wrong and pastes it back into the chat. They found that quick, visual loop shaped the game's design as well as the code.

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.
