Crozzle
Crosswords built fresh every time: from a ready-made category, from your own topic, or as the crossword of the day.
Instead of the same newspaper crossword, Crozzle lays out a new grid for every game. Pick a level and a category, or type your own topic and Claude prepares the clues for it.
What it does
- Four levels: Little ones (6–8), Kids (9–12), Easy and Hard for adults
- More than a dozen categories, from animals and geography to space, history and jobs
- Your own topic: answers and clues written by Claude, a language model
- Crossword of the day, stars and a daily streak
- A keyboard with Polish letters and hints, comfortable to play on a phone
How I built it
The grid generator is a separate module with no UI, covered by tests. Every answer in the word base is validated automatically, and Playwright tests play through the game on phone and desktop.
