The objective of the game is to drive a bus from Tucson, Arizona, to Las Vegas, Nevada, in real time at a maximum speed of 45 mph (72 km/h). The feat requires eight hours of continuous play to complete.
The bus contains no passengers, there is little scenery aside from an occasional rock or bus stop sign, and there is no traffic. The road between Tucson and Las Vegas is completely straight. The bus veers to the right slightly, and thus requires the player’s constant attention. If the bus veers off the road it will stall and be towed back to Tucson, also in real time. If the player makes it to Las Vegas, one point is scored.
