In the game the player controls a car, picking up dots in a maze (pre-dating Pac Man by a year) while attempting to avoid the rival cars which attempt to crash into you. There are five "lanes" which you may only cross at four different points on the map, however there is an acceleration pedal which will allow you to avoid the enemy car with more ease.
Despite its simplicity, Head On went to inspire numerous clones and sequels, including Head On N by Sega's future rival, Nintendo. Super Crash and Car were also arcade variations of the game. Head On 2 is almost an exact copy of Head On, but features a different map. The game was included in 1997 as part of Sega Memorial Selection Vol.1 for the Sega Saturn, as well as part of the Sega Ages 2500 series on the PlayStation 2. Ports of the game in one form or another also appeared on the Game Boy, Commodore 64, Apple II and VTech Laser-VZ
