Sumitting Prediction Based Website

I have a prediction based game site which i am trying to submit in a suitable category/subcategory in Dmoz. But, i am not finding any suitable place to put my site information. Can anybody suggest me the ideal place or the process to go through the proper category/subcategory?

Basically, you search down through the categories till you find the closest one to the content of your site, then use the "suggest site" link at the top of the category.
From your description of the site, I'd imagine somewhere under Games.
