I'll help you build a 4x4 tic-tac-toe game in Python with a clean terminal interface. Let me create a comprehensive plan for this project.

Project Plan: 4x4 Tic-Tac-Toe Game

Core Components:

1. Game Board Management

   • 4x4 grid representation using a 2D list
   • Clear board display with grid lines and position numbers
   • Minimalistic color scheme using ANSI escape codes

2. Player System

   • Two players: X and O
   • Turn-based gameplay with player switching
   • Player input validation (position 1-16)

3. Win Detection Logic

   • Check all 4 rows for 4-in-a-row
   • Check all 4 columns for 4-in-a-row
   • Check both diagonals for 4-in-a-row
   • Return winning player or None

4. Game Flow

   • Main game loop
   • Display current board state
   • Handle player input
   • Check for win/draw conditions
   • Game over handling with replay option

5. User Interface Design

   • Clean terminal display with colored elements

   • Color scheme:

     • Player X: Blue
     • Player O: Red
     • Grid lines: Gray
     • Instructions: Green
     • Background: Default terminal

Technical Implementation:

• File Structure: Single Python file (tic_tac_toe.py)
• Dependencies: Only standard library (no external packages)
• Input Method: Numbered positions (1-16) for easy user interaction
• Error Handling: Invalid input validation and clear error messages

Key Features:

1. Intuitive Position System: Players choose positions 1-16 instead of coordinates
2. Visual Feedback: Colored player symbols and clean grid display
3. Comprehensive Win Detection: All possible 4-in-a-row combinations
4. Draw Detection: When all 16 positions are filled with no winner
5. Replay Functionality: Option to play again after each game

Game Rules:

• 4x4 board instead of traditional 3x3
• Players need 4 in a row to win (horizontally, vertically, or diagonally)
• Standard alternating turn system

Would you like me to proceed with this plan, or would you like to modify any aspects of the design? Once you're satisfied with the plan, please toggle to Act Mode (⌘⇧A) so I can implement the game.
