This Hunger Games Simulator exists because we were displeased with the other simulators out there; the one that we were using prior to the creation of this one (the one at brantsteele.net) made it very difficult to upload images and was utilising a needlessly convoluted server-driven system.
This simulator was created to address both of those shortcomings. With it, you can easily upload whatever images you want. You can also just give it a URL that points to a publicly accessible image, and it will work just fine—so long as your browser supports it, that is.
What's more, this simulator runs entirely in the browser, meaning that you could even download the page and use it offline if you so desired. This also means that it should be faster than the simulator we were using before, since it does not need to send data to a server and back every single time you press a button.
