We can use online services such as to do the job but today we are going to use a small Firefox extension that is going to do the same on-the-fly, so we can later use Firebug to debug the JavaScript code. This makes the analysis a bit harder but we can try some tricks in order to make our job more easy.įirst of all is to format the file again. There we can see they are loading a file, bday13.js which is obfuscated and minimised. This is not the Google home page as there the code is more complex and we want to focus in the relevant files. This is a post about how I dissect the JavaScript code and tweaked my Firefox with some plugins in order to smash some high scores.įirst of all we need to go to the Doodle page. This kind of games uses canvas, audio and some other fancy HTML5 features to display flash-like games (good old times using flasm to decompile them…) plus some obfuscation and JavaScript tricks to avoid easy hacks.

So today is Google 15th anniversary and they released a mini game in HTML5 to celebrate it.
