History of the board game Monopoly as a game called "Inflation", designed by Rudy Copeland and published by the Thomas Sales Co., in Fort Worth, Texas, also came to the attention of Parker Brothers management in the 1930s, after they began sales of "Monopoly". Copeland continued sales of the latter game after Parker Brothers attempted a patent lawsuit against him. Parker Brothers held the Magie and Darrow patents, but settled with Copeland rather than going to trial, since Copeland was prepared to have witnesses testify that they had played "Monopoly" before Darrow's "invention" of the game. The court settlement allowed Copeland to license Parker Brothers' patents.
Camelot (board game) considerably more varied than checkers. Parker created a game that was a complex, tactical, but an easily learned and quickly played mixture of Halma and checkers. When finally published by Geo. S. Parker & Co. in 1887, Chivalry won the raves of chess and checkers experts, but the game Parker called "the best game in 2000 years" did not catch on quickly with the general public. However, Parker never lost his enthusiasm for the game, and in 1930 he made a few changes, and Parker Brothers republished it under the name "Camelot". A few more rules changes followed in 1931.
