Play Codename: Kids Next Door Games: Downhill Derby Online

Codename: Kids Next Door Games: Downhill Derby was a Flash Classic racing game released on the Cartoon Network website, developed by Cartoon Network and Atomic Planet Entertainment. It appeared during the mid-2000s when browser games were a primary way to engage with your favorite cartoons online, offering a straightforward arcade experience tied directly to the show.

You control one of the Kids Next Door operatives in a makeshift cart, racing down a hill against other characters. The main objective is to finish in first place across a series of tracks. Your primary actions are steering left and right to stay on course and pressing the spacebar to jump over obstacles like rocks or gaps. You also collect power-ups scattered on the track, which can give you a temporary speed boost or disrupt your opponents. The races are short and fast, with the difficulty coming from tight corners and the other carts jostling for position. It feels like a chaotic, slightly unpredictable scramble to the finish line.
