The term "1-up" may come from Japanese wasei-eigo (Japanese
English). “~ UP” (Japanese: ～アップ) means “to raise the ability
of; to increase.” Other examples include “Power up,", and
“Ability UP!". This Japanese terminology has provided video
games with another popular phrase, level up. Pinball games often
gave players multiple chances. When a ball was lost in the
gutter, the next ball was loaded and the game continued. If a
player met certain conditions (such as a high score), he or she
received an "extra ball," or "extra life." Later, this concept
was applied to arcade games. The inclusion of extra lives was
very common in video games from the 1980s on, even in otherwise
'realistic' combat-themed games. "1-up" was first seen in multi-
player pinball and other arcade games. In these games, "1UP"
meant that it was player one's turn. Likewise, "2UP" meant it
was player two's turn, and so on. In some cases, arcade games
also used this terminology to designate which score was whose.
