The goal of the game is pretty straightforward. You have to drive a Bus through the desert from Tucson, Arizona to Las Vegas. The hard part is that the whole trip is in real-time, so it takes 8 hours at least. There is no scenery or even other cars on the road, just plain desert, for 8 hours. Oh, and your bus veers to the right just slightly, so it’s impossible to just tape down a button and go do something else. Rumor has it that if you make it to Vegas, you score one point.
