Minesweeper.js

Build Status

By Michael Butler

A WebWorker powered Minesweeper game written in JavaScript, HTML and CSS. Yes, using webworkers just for minesweepr might be overkill but for when this was first written around 2013 it actually made a visible difference in Firefox at least. But it is also an exercise to understand how they work and pass messages between the main UI thread and the background thread.

Demo: https://michaelbutler.github.io/minesweeper/

Features:

  • User can choose difficulty level
  • Custom option with configurable grid size (X, Y) and number of mines
  • Stopwatch with score keeping (LocalStorage)
  • Stack based grid traversal algorithm for memory efficiency
  • HTML5 web worker (if supported) will be used to perform the stack algorithm outside of the UI thread

How to use:

Download all the files and open index.html in a modern web browser.

Example HTML usage:

<!-- requires jQuery -->
<h1 class="logo">JavaScript MineSweeper
    <div class="invisible ajax-loading"><img src="load.gif" alt="Processing..."/></div>
</h1>
<div id="minesweeper"></div>

<script src="js/MineSweeper.js" type="text/javascript"></script>
<script>
    // set a global instance of Minesweeper
    minesweeper = new MineSweeper();
    minesweeper.init();
</script>

To Do:

  • Add animation and better graphics
  • Enhance UI for a sleek new look
