Super Tux Kart
Super Tux Kart is a great Mario Kart clone. If you feel like some racing fun, check it out.
It comes with a bunch of courses, and is playable on lots of different platforms. I’ve played on my PC, from my couch, on a tablet, and on a phone. For each of these platforms, they have different control inputs. For instance, if you have phone with gyros/accelerometers in it, you can turn the phone like a steering wheel to control it.
Fun for all ages!
