Overview

A daily code-breaking logic puzzle: a fresh hidden color code each day, a fixed number of guesses, and feedback after every try telling you how close you are. Solve it, keep your streak, and share a spoiler-free result grid. One puzzle a day, the same for everyone — the hook is the daily ritual and the streak.

How it works

The whole thing runs on a single Cloudflare Worker that serves both the JSON API and the static front end. The front end is a small vanilla-TypeScript SPA (built with Vite, no framework): a mobile-first board with keyboard input, undo, local persistence of your day’s progress and stats, and a PWA shell with offline support.

The daily puzzles live in KV, precomputed ahead of time so the same code is served to every player. The hidden code never reaches the browser — guesses are scored server-side and the API returns only the closeness feedback, so the answer can’t be sniffed from network traffic. Anonymous aggregate “how everyone did today” stats are tracked in a Durable Object. The daily game lives at /classic, with an endless practice variant and additional modes routed off a small hub at the root.
