In [[Video game|computer and video games]], scrolling of a playing field allows the player to control an object in a large contiguous area. Early examples of this method include [[Taito]]'s 1974 vertical-scrolling [[racing video game]] ''[[Speed Race]]'',<ref>{{KLOV game|id=9709|name=Speed Race}}</ref> [[Sega]]'s 1976 [[2.5D|forward-scrolling]] [[racing game]]s ''[[Fonz (arcade)|Moto-Cross]]''<ref name=Moto-Cross>{{KLOV game|12812|Moto-Cross}}</ref> (''Fonz'')<ref name=Fonz>{{KLOV game|id=12812|name=Fonz}}</ref> and ''Road Race'',<ref name=Road-Race>{{KLOV game|12733|Road Race}}</ref> and ''Super Bug''. Previously the [[flip-screen]] method was used to indicate moving backgrounds.

The [[Namco Galaxian]] [[arcade system board]] introduced with ''[[Galaxian]]'' in 1979 pioneered a [[Sprite (computer graphics)|sprite]] system that animated pre-loaded sprites over a scrolling background, which became the basis for [[Nintendo]]'s ''[[Radar Scope]]'' and ''[[Donkey Kong (arcade game)|Donkey Kong]]'' arcade hardware and [[home console]]s such as the [[Nintendo Entertainment System]].<ref>[https://web.archive.org/web/20120505103737/http://www.glitterberri.com/developer-interviews/how-the-famicom-was-born/making-the-famicom-a-reality/ Making the Famicom a Reality], ''Nikkei Electronics'' (September 12, 1994)</ref>

[[Parallax scroll]]ing, which was first featured in ''[[Moon Patrol]]'', involves several [[transparency (optics)|semi-transparent]] layers (called playfields), which scroll on top of each other at varying rates in order to give an early [[2.5D|pseudo-3D]] illusion of depth.<ref>{{cite web|url=http://www.gamesradar.com/f/gamings-most-important-evolutions/a-20101008102331322035/p-3|title=Gaming's Most Important Evolutions|page=3|publisher=[[GamesRadar]]|date=October 8, 2010|access-date=2011-04-27}}</ref>

'''{{vanchor|Belt scrolling}}''' is a method used in side-scrolling [[beat 'em up]] games with a downward camera angle where players can move up and down in addition to left and right.
