🚀 Building an AI Solver for a Puzzle Game Was More About UX Than AI

When people hear AI puzzle solver, they usually imagine the difficult part is finding the correct solution.
After looking into a Magic Sort puzzle solver project recently, I realized something surprising.
The hardest problem wasn't solving the puzzle.
It was understanding what the puzzle actually looked like.


🎮 Modern Puzzle Games Aren't Static Anymore
Classic sorting puzzles are predictable.
Modern ones introduce mechanics that completely change the board while you're playing.
Some examples include:
• 🔑 Hidden Keys
• 📦 Locked Box Groups
• 🎭 Curtain-Covered Tubes
• 🏷️ Tag Tubes
• 🧊 Ice Clusters
• 🌫️ Fog Stones
• ❓ Hidden Color Segments
• ♻️ Refill Short Tubes
Every one of these changes the puzzle state.
That means a solver can't simply calculate moves from a screenshot and call it a day.


🤖 Computer Vision Is Only Step One
The project uses a custom YOLO model to reconstruct the visible board from a screenshot.
Once the board is detected, a heuristic search explores possible move sequences.
Sounds straightforward...
Until the game reveals something that wasn't visible in the original screenshot.
At that point the solver has to stop, accept new information from the player and continue searching from the updated state.
That hybrid approach felt much more practical than trying to guess hidden information.


💡 The Biggest Lesson
One thing really stood out.
Instead of chasing perfect screenshot detection, the project focuses on making corrections easy.
When AI misses something, the player can quickly update the board and continue solving.
That simple UX decision removes a lot of frustration.
Sometimes the best AI experience isn't perfect automation.
It's designing a workflow that gracefully handles imperfect predictions.


🛠️ Technologies Behind the Idea
Nothing here is particularly exotic on its own.
The interesting part is how everything works together.
• 🎯 YOLO for board detection
• 🧠 Heuristic search for move planning
• ⚛️ React / Next.js for the interface
• 🎨 Interactive board editing
• 🔄 State updates as the puzzle evolves
Each component solves a different problem.
Together they create something that feels much smarter than any individual piece.

🎯 Final Thoughts
Projects like this remind me that AI is rarely the whole product.
A useful developer tool is usually the combination of:
• ✅ Computer vision
• ✅ Search algorithms
• ✅ Clear game rules
• ✅ Good UX
• ✅ User feedback loops
Remove any one of those pieces and the overall experience quickly starts to break down.
I'd be interested to hear how others approach projects where the AI never has complete information from the start.
