In many role-playing games and computer and video games, a critical hit is a successful attack that deals more damage than a normal blow. The name and concept of critical hits originated in the fantasy role-playing game Dungeons & Dragons, and migrated from there into other role-playing games and computer role-playing games, and from there into video games outside the role-playing genre.
