Block-Reign: A Player vs AI Grid Game That Learns From You

#ai #gamedev #python #opensource

Most game AIs are fake smart.

Patterns, scripts, predictable behavior.

Block-Reign isn’t.

This is a lightweight Player vs AI grid battle game where the AI actually learns from every match you play — wins, losses, mistakes, all of it.

No GPU.

No fancy engines.

Just Python, reinforcement learning, and persistence.

🕹️ What Is Block-Reign?

Block-Reign is a 10×10 grid-based Player vs AI combat game built with:

Flask + HTML for the frontend
Python for the game server
Reinforcement Learning (Q-Learning) for live gameplay
DQN for advanced offline experimentation

You play in the browser.

The AI plays on the server.

After every match, it gets smarter.

🤖 The AI Philosophy

The core idea was simple:

What if the AI learned only from real games — not pre-trained data?

So the AI:

Starts dumb
Learns only from actual matches
Saves its knowledge permanently
Adapts to your playstyle

No synthetic data.

No scripted behaviors.

Just experience.

🧠 How Learning Works

The running server uses a Q-learning AI
After each completed match:
- Match data is sent to the server
- The AI updates its Q-table
- Progress is saved on disk
Restart the server → the AI remembers everything

The project also includes a DQN trainer (ai_trainer.py) for experimentation.

📊 Current AI Progress

As of the latest run:

Win rate: ~59%
Matches played: 78
Record: 46 Wins / 36 Losses

These stats are not hardcoded.

They are learned, stored, and persisted.

Delete the training folder, and the AI forgets everything.

🎮 Gameplay

10×10 grid
Arrow keys to move
Space to shoot
Simple mechanics, strategic positioning
Fast matches, instant feedback

Minimal visuals.

Maximum behavior learning.

🔁 Resetting the AI

Delete:

training/

or:

training/models/simple_ai.pkl

Restart the server and play again.

The AI starts from scratch.

🛠️ Why I Built This

This project wasn’t about graphics or polish.

It was about:

Understanding reinforcement learning
Watching an AI evolve organically
Building adaptive systems without massive compute

Final Thought

Block-Reign isn’t perfect.

But it’s honest.

An AI that earns its intelligence one loss at a time.

And nah — this isn’t the end.
Wilder strategies. Sharper gameplay. Better graphics.
Something crazier is coming. Wait for it 👀

Jei ieškote patogios vietos susipažinti su internetinio kazino pasiūla, verta pradėti nuo pagrindinio puslapio ir peržiūrėti, kaip išdėstytos skirtingos kategorijos. Twinsbet Casino galima rasti įvairių žaidimų bei informacijos apie platformoje siūlomas pramogas. Man patinka pirmiausia apžiūrėti bendrą svetainės struktūrą, o tik tada rinktis konkrečius žaidimus. Taip pat verta atkreipti dėmesį į aktualias taisykles, mokėjimo sąlygas ir atsakingo žaidimo informaciją. Skirtingų platformų palyginimas padeda geriau suprasti, kokios funkcijos jums iš tikrųjų svarbios.
