About

A hidden code. Every guess returns one number: how many colors sit in the right place. Take your time, try a few ideas and see what you can work out. 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: 49 levels across seven chapters. Decoys, repeats, fog, frozen cells and chained codes. In the new Monochrome chapter, the familiar colors give way to shades of gray. - 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 helped you find the answer. - Achievements: follow 18 goals across Campaign, Daily, Duels and Infinite. A LITTLE HELP Earn marbles by clearing new Campaign levels, solving the Daily, winning online duels and unlocking achievements. Use them to reveal a color or take one more turn in Campaign and Infinite when hints are available. Daily and duels stay hint-free. THE HONEST PART - Free. No ads. No payments. - Campaign, Infinite and Ghost Duels work offline. - No account needed for solo play. Sign in for cloud sync and online duels. - Daily needs an internet connection. - Marbles are earned through play and saved on your device. They cannot be bought with money. Just you and the code.

What's New in Color Decoder

1.4

September 19, 2026

Color Decoder 1.4: Monochrome In this update, I added Monochrome: eight new levels that swap colors for shades of gray. The rules will feel familiar, but you might need to look a little closer :) That brings Campaign to 49 levels across seven chapters, with a new achievement for finishing this one. I also reworked hints a little. You'll earn marbles for clearing new Campaign levels, solving the Daily, winning online duels and unlocking achievements. Use them to reveal a color or take one more turn when you feel close to the answer. You'll find both under “Need a hand?” on the board. Marbles are earned only by playing; there's nothing to buy with real money. Daily and duels still have no hints. In duels, I removed the extra screens between rounds and made leaving a match clearer. If you decide to leave early, the game will no longer show a score that never happened. I also worked on round synchronization and how the game handles a lost connection. And a few small changes on the home screen: I brought your stats together and gave the Daily button softer colors and a gentle animation. The familiar menu is still in place. Thanks for playing. I hope you enjoy the new chapter!
