About CodePop

A daily colour puzzle for people who love logic, patterns, and a satisfying crack.

What is CodePop?

CodePop is a free browser-based puzzle game inspired by the classic Mastermind board game. Each day a new secret 4-colour code is set and shared with everyone. You have 8 guesses to crack it, using colour-coded feedback pegs to home in on the answer.

A fresh puzzle drops at midnight every day. Your streak, wins, and guess history are all stored locally in your browser - no account, no sign-up, no email.

Why we built it

We love daily puzzle games and wanted to bring the tactile satisfaction of Mastermind to the browser in a clean, focused, modern form. CodePop strips away everything unnecessary - no ads in your face, no accounts, no push notifications - just the puzzle.

Practice mode exists because some days you just want to keep going. No limits, no pressure - just codes to crack.

How it works

  • +Each daily code is deterministic - generated from today's date so everyone plays the same puzzle worldwide.
  • +Your game state and statistics are stored in your browser's localStorage - they stay on your device.
  • +Standard mode uses 4 distinct colours. Expert mode allows repeats, making deduction significantly harder.
  • +The share feature copies an emoji grid of your guesses - no spoilers, just the pattern.
