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!

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.

Updates, new features and bug fixes: 1. The game now works offline. Campaign, endless mode and ghost duels need no connection. 2. Ghost duels race real players: recorded runs of other people, marked with their names. 3. Fixed the daily code: one code for the whole world now. Same puzzle, same code, every day. 4. Reworked game analysis: it now shows which codes were still possible after each guess. 5. Daily results share updated: a single card with a QR code. Removed spoilers from the image. Extra: added "wave" achievements in endless mode, nickname changes, mechanic icons in the campaign, and many small fixes.
