Simon is the dazzling electronic light-show offspring of the age-old game “Simon Says.” You remember “Simon Says,” it’s that game children usually end up playing in the backyard at family gatherings when they can’t find a wi-fi signal for their smartphones. Invented by Ralph H. Baer and Howard J. Morrison in 1978, Simon exercises the child’s mind as well as heightens their sense of perception by giving them a series of light and sound patterns to imitate. It works great with younger children also, helping them learn the colors while keeping them quietly mystified. Emphasis on quiet. While some video games have the same effect, parents can rest assured that the only violence that may spring from this activity is between the kids who can’t wait their turn to play it.
