A fun and interactive RGB Color Guessing Game built using Devvit! Test your knowledge of RGB color components and improve your color intuition with this engaging and visually appealing game.

Inspiration

What inspired me to build Guess Color Combo was a personal challenge: I wanted to create a fun game that helps people intuitively understand RGB color combinations, especially designers, developers, and color lovers. I’ve always been fascinated by how colors blend, and I thought—why not turn that into a game that’s both educational and addictive?

I chose to build it using Devvit because it offered a unique way to deliver interactive experiences directly on Reddit. Being able to embed a game within a subreddit and let people play without leaving the platform felt like the perfect approach for engagement.

🕹️ What It Does

Guess Color Combo is an RGB color guessing game where players test their ability to recognize and match RGB values to their corresponding colors.

A random RGB color is displayed.
The player chooses from four RGB combinations to guess the correct one.
Players have two attempts per round:
- First correct guess: +10 points (increases with level)
- Second correct guess: +5 points
- If both fail, the correct answer is shown, and the round ends.
The game includes:
- Live scoring -Leaderboard to see how other redditors are performing
- Bonus points for speed and higher levels
- Animated feedback
- A "Well done!" message
- A Restart Game option when you fail

Writing tests for the screens It was quite challenging to know what setup would work.
Worked on sound effects but removed it, because it not yet supported.
Creating a balance between fun and difficulty took time.
