Key Algorithms
The AI uses a Minimax algorithm with depth-limited recursion to determine optimal moves:
function minimax(board, depth, isMaximizing) {
// Base cases: check for wins/losses/ties
if (checkWin(currentPlayer)) return 10 - depth;
if (checkWin(opponent)) return -10 + depth;
if (checkTie()) return 0;
if (isMaximizing) {
let bestScore = -Infinity;
// Evaluate all possible moves
return bestScore;
} else {
let bestScore = Infinity;
// Evaluate all possible opponent moves
return bestScore;
}
}

Game State Management
The game maintains several key state variables:
let board = ['', '', '', '', '', '', '', '', ''];
let currentPlayer = 'X'; // X or O
let gameActive = false; // Game status
let scores = { playerX: 0, playerO: 0, ties: 0 };
let playerTypes = { X: 'human', O: 'ai' };
let lastWinner = null; // For turn alternation
