Later career and retirement
Milton and the company that bore his name continued with great success. The mid to late 19th century business climate in America was rife with labor disputes and strikes, but the Milton Bradley company remained free of all that. He ran an informal workplace. Everyone called him by his first name. As he got older, he sometimes told the factory to shut off the machines for an hour or so, and he would take a nap in his office.
The 1880’s saw the Milton Bradley company marketing jigsaw puzzles for children, starting with “The Smashed Up Locomotive”. Prior to this, jigsaw puzzles were geared toward adults. The company also mass produced 15-tile “sliding puzzles”.
By 1881, the MB company had branch offices all over the country, from San Francisco to Atlanta to Boston. His family grew as well. His daughter Florence was born in 1874, and another daughter, Lillian was born in 1881. His daughters often had friends over to play at their house and Milton provided then with plenty of games to play with. In 1889. He moved into an even larger house and invited his wife’s parents to come live with them. Milton and Nellie became well known for throwing lavish parties, with plenty of party games, of course.
His house was very large and comfortable but not ornate or ostentatious, like many of his fellow Gilded Age industrialists. He had few luxuries. That is, until luxury automobiles were invented! He enjoyed driving his fancy car around town and waving to people on the street. 
Milton finally retired in 1906. He and his family often visited a vacation home in Harpswell, Maine, the state of his birth. Later that family included his three grandchildren as well.
Milton Bradley died on May 30, 1911 at age 74. His own path on the Game of Life had brought him to wealth, happiness, and the esteem of game players and kindergartners the world over.
