Color Decoder
Read full descriptionHide full description
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
The clearest difference is in-app purchases: Color Decoder at none against Word Chain Reaction's 19. Color Decoder also leads on ads (none vs shown) and update cadence (fortnightly vs monthly). On price, device support and iOS requirement there is nothing between them.
