I Built a Puzzle Game to make Graph Coloring Easier to Understand

Short summary

A CS student built 3Color Simulator, a browser-based puzzle game teaching graph 3-coloring through play rather than textbook theory. After launching, user feedback revealed a critical gap: technically correct games can still confuse users without clear instructions, visual feedback, and thoughtful progression. The author's key takeaway—small UX details matter as much as algorithmic elegance—applies broadly to any educational product.

  • •Educational puzzle game that makes abstract graph 3-coloring intuitive through interactive play
  • •Built with React, Vite, and deployed on Vercel; includes level progression and conflict detection
  • •Emphasizes UX and user feedback loops over pure technical correctness

Generated with AI, which can make mistakes.
