This is a list of games that used to be played by children, some of which are still being played today. Traditional children's games do not include commercial products such as board games but do include games which require props such as hopscotch or marbles (toys go in List of toys unless the toys are used in multiple games or the single game played is named after the toy; thus "jump rope" is a game, while "Jacob's ladder" is a toy). Despite being transmitted primarily through word of mouth due to not being considered suitable for academic study or adult attention, traditional games have, "not only failed to disappear but have also evolved over time into new versions."
