Javascript result to open a new page in same window

I'm using the code for this roulette on codepen for a personal project: http://ift.tt/1D0SFGF. It's all working fine but I'm trying to have the result of the roulette open a specific page in the same window. I'm not sure to target the result of the roulette. My approach was to set values to each variables and create a function:

function openDestinationResult() {
    var $100 = "index.html";
    var $200 = "content.html";
    ...
   if ($100 === "$100")
    {
        document.location.replace("result1.html");
    }
    else if ($200 === "$200")
    {
        document.location.replace("result2.html");
    }

but this obviously doesn't work. I'm new at using javascript so bear with me!

Thanks for any tips/solutions.

cheers
