Head On is an arcade video game developed by Sega/Gremlin and released by Sega in 1979. It's the first maze game where the goal is to run over dots. Designed by Lane Hauck at Sega/Gremlin in the United States, it was the fourth highest-grossing arcade game of 1979 in both Japan and the US.

Gremlin Industries was an American arcade game manufacturer active from 1970 to 1983, based in San Diego, California. It was acquired by Sega in 1978, and afterwards was known as Gremlin/Sega or Sega/Gremlin. Among Sega/Gremlin's most notable games are Blockade and Head On, as well as being the North American distributors for Frogger and Zaxxon. The company's name was subsequently changed to Sega Electronics in 1982, before its operations were closed in 1983.
