License your game to domain(s), protect your games.

Notice this isn't 100% protective but offers a good solution.

1. Export your game (HTML5).

2. Open index.html file in editor (notepad++)

3. Find <body> tag.

4. Copy and paste under <body> tag:

    var referrer = document.domain; // The result of referrer will be: www.domain.com
    if(referrer == "www.yourdomain.com"){ 
     // Use || for multiple domains like : if(referrer == "www.yourdomain.com" || "www.seconddomain.com"){ 
    window.myValue = true;
    }else{
    document.write("Access denied");
    window.myValue = false;
    }


5. When you are done setting up the domains go to : javascriptobfuscator.com/Javascript-Obfuscator.aspx[/b]

6. Paste your code & click the obfuscate button:

7. Copy everything and change it with your current code under <body>

Like :

    	<script>
    var _0x5217=["\x64\x6F\x6D\x61\x69\x6E","\x77\x77\x77\x2E\x79\x6F\x75\x72\x64\x6F\x6D\x61\x69\x6E\x2E\x63\x6F\x6D","\x6D\x79\x56\x61\x6C\x75\x65","\x41\x63\x63\x65\x73\x73\x20\x64\x65\x6E\x69\x65\x64","\x77\x72\x69\x74\x65"];var referrer=document[_0x5217[0]];if(referrer==_0x5217[1]){window[_0x5217[2]]=true}else {document[_0x5217[4]](_0x5217[3]);window[_0x5217[2]]=false;};
    	</script>

8. Find <script src="c2runtime.js"></script>

9. Replace it with :

    	<script>
    var _$_4a06=["\x6D\x79\x56\x61\x6C\x75\x65","\x3C\x73\x63\x72\x69\x70\x74\x20\x73\x72\x63\x3D\x22\x63\x32\x72\x75\x6E\x74\x69\x6D\x65\x2E\x6A\x73\x22\x3E\x3C\x2F\x73\x63\x72\x69\x70\x74\x3E","\x77\x72\x69\x74\x65"];if(window[_$_4a06[0]]==true){var _0xe376=[_$_4a06[1],_$_4a06[2]];document[_0xe376[1]](_0xe376[0]);};</script>

10. Save your index.html & control if it's working

Don't forget to post feedback : )

For geeks after you did the process above

If you want to make it really hard for people to steal & use your games use :
