I recently built 3Color Simulator, a browser-based puzzle game based on the graph 3-coloring problem.

The idea is simple: players are given a graph and have to color every vertex using only three colors. The challenge is that no two connected vertices can share the same color.

You can try it here: https://3color.vercel.app/

Why I built it

I’m a Computer Science student, and I’ve always been interested in algorithms, graph theory, and problems like P vs NP.
