Kode. - Crack the 4-digit lock. One new puzzle every day.

Hey PH 👋 I'm the maker of Kode — a daily 4-digit logic puzzle inspired by Wordle and Mastermind. I originally built it in Flutter to target mobile + web, but the web version was too heavy and slow. So I rebuilt it in Preact + Firebase with a mobile-first approach and way faster load times. The goal was to keep it simple: 🧩 1 puzzle per day 🔒 No accounts 🧠 Pure logic, no guessing Would love to know what you think — especially if the logic feels satisfying, and if the UX holds up on mobile. Also open to ideas on what to add next 🙏 Thanks for checking it out!
