'''Handheld electronic games''' are interactive [[electronic game]]s, often miniaturized versions of [[video games]], that are played on portable [[handheld device]]s, known as [[handheld game console]]s, whose controls, display and speakers are all part of a single unit. Rather than a general-purpose screen made up of a grid of small [[pixel]]s, they usually have custom displays designed to play one game. This simplicity means they can be made as small as a [[smartwatch]], and sometimes are. The visual output of these games can range from a few small light bulbs or [[light-emitting diode|LED]] lights to calculator-like alphanumerical screens; later these were mostly displaced by [[liquid crystal display|liquid crystal]] and [[vacuum fluorescent display]] screens with detailed images and in the case of VFD games, color. Handhelds' popularity was at its peak from the late 1970s into the early 1990s before declining. They are the precursors to the [[handheld game console]].
