Apparently it's free for today only, meaning that gamers that haven't bought Sega's ported Dreamcast classic should immediately do so. Just follow the link and grab ChuChu Rocket! for your iPhone, iPod or even iPad. Mind you, it's not the best conversion possible as Sega has apparently been its recent lazy self, but it remains an immensely fun, fast-paced and great looking puzzle game. Oh, and it happily supports multiplayer too.
