The Game of Life, also known simply as LIFE, is a board game originally created in 1860 by Milton Bradley, as The Checkered Game of Life (and later produced by the Milton Bradley Company of Springfield, Massachusetts). The Game of Life was America's first popular parlor game. The game simulates a person's travels through his or her life, from college to retirement, with jobs, marriage, and possible children along the way. Two to six players can participate in one game, however, variations of the game have been made to accommodate a maximum of only eight or ten players. The modern version was originally published 100 years later, in 1960. It was created by toy and game designer Reuben Klamer and was 'heartily endorsed' by Art Linkletter. It is now part of the permanent collection of the Smithsonian's National Museum of American History. It later spawned a book, The Game of Life: How to Succeed in Real Life No Matter Where You Land (Running Press), by Lou Harry.
