Newgrounds might have the lofty tagline "Everything. By Everyone," but what that translates to is a collection of funny and highly irreverent online games. Users can submit their own games to the Newgrounds collection, where the community ranks them and highlights the best ones. While there are some traditional side-scrolling or tower-defense choices in the mix, there are also zanier picks like "Freeway Fallguy." But parents, be warned: not everything on the site is safe for kids.
