Socket, known in Japan as Time Dominator 1st (タイムドミネーター1ｓｔ), is a fast-paced platform game developed and published by Vic Tokai for the Mega Drive/Genesis. It was released on August 17, 1993. The game was not released in Europe or Australia.

Socket plays very similarly to Sonic the Hedgehog; so much so that it is often called a Sonic rip-off or clone. Its sense of speed and platforming gameplay contributed to this thinking. In this game players collect energy (represented by lightning bolts) which the robot Socket consumed when he moved. This energy also served as the "life meter", rather like the golden rings in Sonic. The stages were named to reflect this fast paced gameplay. All the zones followed a three-act pattern, beginning with a fast-paced racing zone, followed by a more platformer-style area, and ending with a more puzzle-style labyrinth. This is followed by a boss battle.
