I made this project as an experiment after seeing a post on X from someone struggling to make word puzzles with AI. I wanted to see how far AI could go beyond its native capabilities when it could work through a coding environment, with feedback from the running result.
The workflow produced a playable Czech arrowword crossword with a hidden phrase.
The result
With Claude and a feedback loop, the project got quite close to 100% completion. After a few refinements and codifying the workflow into a reusable skill, the experiment turned out surprisingly well: not just a generator, but a puzzle that is fun to play on a computer and ready to print.
The finished puzzle reveals its hidden phrase below the grid.
