Snake Game

Play classic Nokia snake game by reinforcement learning with Keras. This project is a great starting point to learn how reinforcement learning works and implementation of deep learning with Keras. Keras is a high level Python deep learning library based on Theano or TensorFlow. We use Q-learning to teach snake how to move. This Q-learning tutorial is an awesome material to get the idea how it works.

• Play the game

Code Structure

Play the game

python terminal.py

Simply move the snake by arrow keys ←, → ↑ ↓.

• 1: snake or wall
• F: target fruit

Train the bot

python run_bot.py

Trained model is saved to /models with its json structure and weights by default.
