A modern implementation of the classic Connect Four game with customizable board sizes and an elegant user interface.

Connect Four is a two-player strategy game where players take turns dropping colored discs into a vertically suspended grid. The objective is to be the first to form a line of four discs of your color horizontally, vertically, or diagonally.

• Two-player gameplay with Navy (X) and Turquoise (O) discs
• Configurable board sizes (8x5, 10x6, 12x7)
• Visual player turn indicators
• Win detection with animated golden highlighting
• Modern, flat UI design with hover effects
• Automatic new game option after win/draw

Built using Model-View-Controller (MVC) architecture:

• Model: Handles game logic and state
• View: Custom-drawn components using Java2D
• Controller: Manages user interactions and updates

• Dynamic resizing while maintaining UI proportions
• Maintains circular piece aspect ratio
• Multiple standard board size support

• Modern flat UI design
• Circular disc slots with smooth edges
• Animated winning highlights with golden glow effect
• Responsive hover effects on interface elements

• Manages individual board positions
• Handles player symbols and colors
• Provides state checking functionality

• Implements game logic and move validation
• Win condition detection
• Game state management

• Handles user interactions
• Updates visual game state
• Manages animations and highlights

• Creates and manages the main game interface
• Handles menu system
• Manages board size changes

• Custom-drawn circular buttons
• Handles highlighting and animations
• Manages visual states

1. Players take turns clicking on a column to drop their disc
2. Discs fall to the lowest available position in the chosen column
3. First player to align four discs wins
4. Game ends in a draw if the board fills up without a winner

The game has been thoroughly tested with:

• Basic gameplay mechanics
• Win conditions (horizontal, vertical, diagonal)
• Draw conditions
• Invalid move prevention
• UI responsiveness
• Animation smoothness
• Menu functionality

• Java Runtime Environment (JRE)
• Graphical display support
• Minimum resolution to accommodate largest board size (12x7)

Potential areas for future development:

• Network multiplayer support
• AI opponent
• Custom board sizes
• Score tracking
• Game replay functionality
