TicTacToe Game

Problem

Create an engaging, interactive TicTacToe game that demonstrates React fundamentals while providing a smooth, modern user experience. The game needed to be responsive, accessible, and visually appealing with clear game state management.

Approach

• Built with React functional components and hooks for state management
• Implemented game logic with clean, maintainable code structure
• Designed responsive UI with modern CSS styling and animations
• Added accessibility features for inclusive gameplay
• Created intuitive game flow with clear visual feedback

Solution

Developed a fully functional TicTacToe game with React that features turn-based gameplay, win detection, game reset functionality, and a clean, modern interface. The game includes visual indicators for current player, game status, and smooth transitions between game states.

Technical Stack

React, CSS3, JavaScript ES6+, HTML5, Git version control

Key Features

• Turn-based gameplay with X and O players
• Automatic win detection for rows, columns, and diagonals
• Draw detection when no winner is possible
• Game reset functionality to start new games
• Responsive design that works on all screen sizes
• Visual feedback for current player and game status
• Accessible keyboard navigation and screen reader support

Code Snippet

// Game state management with React hooks
const [board, setBoard] = useState(Array(9).fill(null));
const [xIsNext, setXIsNext] = useState(true);

const handleClick = (i) => {
  if (calculateWinner(board) || board[i]) {
    return;
  }
  
  const newBoard = board.slice();
  newBoard[i] = xIsNext ? 'X' : 'O';
  setBoard(newBoard);
  setXIsNext(!xIsNext);
};

const calculateWinner = (squares) => {
  const lines = [
    [0, 1, 2], [3, 4, 5], [6, 7, 8], // rows
    [0, 3, 6], [1, 4, 7], [2, 5, 8], // columns
    [0, 4, 8], [2, 4, 6] // diagonals
  ];
  
  for (let i = 0; i < lines.length; i++) {
    const [a, b, c] = lines[i];
    if (squares[a] && squares[a] === squares[b] && squares[a] === squares[c]) {
      return squares[a];
    }
  }
  return null;
};
