Tic Tac Toe

Objectives

• Build a tic tac toe game in HTML, CSS, and vanilla JavaScript
• Use best practices when writing code

This week we have been learning about HTML/CSS, Javascript and DOM manipulations, and writing functions.

We will be making a Tic Tac Toe game using all of these concepts.

Getting Started

• Fork and clone this repository.
• Before you even start working with JavaScript, construct the gameboard. The gameboard page should include the 3x3 grid (of divs). Using id and class on clickable elements will help you wire this up in JavaScript afterwards.
• The JavaScript portion will be next
  • Select elements and attach functions via event listeners
  • You will also need a variable to keep track of moves. This will be used to indicate whether or not to draw an X or an O

Requirements

• A user should be able to click on different squares to make a move.
• Every click will alternate between marking an X and O
• Upon marking of an individual cell, use JavaScript to add a class to each cell to display the separate players.
• Display a message to indicate which turn is about to be played.
• Detect draw conditions (ties/cat's game)
• Detect winner: Stop game and declare the winner if one player ends up getting three in a row.
  • Hint: Determine a set of winning combinations. Check those combinations on the board contents after every move.

Have Fun - The best way to learn is by playing with code. Let creativity guide you and try some experiments with JS and CSS and see what you can do.

Bonuses

• Implement your reset button without refreshing the whole page
• Track player's wins over time
• Add a simple AI to support one player vs computer mode. In this case, "simple" just means having the computer pick a random empty square.
• Make your computer seem more human by adding a short time delay between your turn and the computer's turn.
• Style it up! Get creative, or even make a theme!

Super Duper Bonus

• Add an AI that can beat you every time with the mini-max algorithm.
