About
A hidden code. Every guess returns one number: how many colors sit in the right place. That is all you get. Solve it anyway.
I made Color Decoder for the moment when a puzzle clicks: three clues on the board, and suddenly only one code can be true. The whole game is built around that moment.
WHAT'S INSIDE
- Campaign: six chapters, each with a new rule. Decoys, repeats, fog, frozen cells and chained codes. More levels are already in development.
- Daily: one code per day, the same for the whole world. Keep your streak going.
- Infinite: waves keep getting harder until one finally ends the run.
- Duels: play a real-time 1v1 or race a run recorded by another player.
- Analysis: after a solo game, see which guesses did the work and which wasted a turn.
- Achievements: follow 17 goals across Campaign, Daily, Duels and Infinite.
THE HONEST PART
- Free. No ads. No payments.
- Campaign, Infinite and Ghost Duels work offline.
- No account needed. Sign in only if you want cloud sync and online duels.
Just you and the code.

What's New in Color Decoder

Achievements finally have a proper home. All 17 are now visible in one place, with clear paths through Campaign, Daily, Duels and Infinite. Progress is easier to follow, earned rewards can be shared, and every unlock gets a small celebration. Daily got a quieter cleanup too. Its button now uses the game's colors while today's code is waiting, the result shows when the next puzzle arrives, and reminders stay out of the way after you have already played. The post-game analysis is also less repetitive and focuses on the guesses that actually mattered. Chain results now keep the whole run together. You can see every round at the finish, share a compact summary of the series, and open a separate analysis for each code.
