Color Decoder

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.

Verdict
