Running the Game

To run this project, you will need to follow the next steps:

1. Download all provided files.
2. Start the server:

   python server.py
   

3. Run the game on each computer you want to play:

   python game.py
   

4. (Optional) Run the AI client:

   python ai_bot.py
   

5. Insert the server IP in the game clients (can be found using ipconfig in Command Prompt)

AI Bot

I integrated an AI bot using the logic made by Yiyuan Lee. Full explanation can be found on Yiyuan Lee's Tetris AI GitHub repository.

Basics of the AI:

The AI bot uses a combination of heuristics to decide the best possible moves for each tetromino. These heuristics include:

• Aggregate Height: The sum of the heights of all columns. Lower aggregate heights are preferred.
• Complete Lines: The number of complete lines that will be cleared with the current move. More lines are better.
• Holes: The number of empty spaces that have at least one block above them. Fewer holes are better.
• Bumpiness: The difference in heights between adjacent columns. Less bumpiness is better.

The AI evaluates possible moves based on these heuristics and selects the move with the best overall score.

Single-Player Cognitive Load Mode

The single_player.py is uniquely designed to test cognitive load. In addition to offering the classic Tetris experience, this mode serves as a practical tool for evaluating how players manage and respond to increasing mental demands1.
