AI Implementation

Minimax Algorithm

The hard AI uses the minimax algorithm, a decision-making algorithm that evaluates all possible game states to find the optimal move. This makes the AI unbeatable when playing optimally.

How it works:

  1. 1. Evaluate all possible moves
  2. 2. Simulate game outcomes recursively
  3. 3. Choose the move that maximizes AI's chances
  4. 4. Minimize opponent's winning opportunities

Game State Management

Efficient state management handles game logic, win detection, and turn management. The system tracks all game states and provides real-time feedback.

Key Features:

  • • Real-time win condition checking
  • • Score persistence across games
  • • Smooth AI move animations
  • • Responsive game board design
