games, in turn, having evolved from the earlier game of Whist. The first documented game of poker dates from an 1833 Mississippi river steamer. During the American Civil War the game was popular with soldiers and additions were made including stud poker, and the straight. Modern tournament play became popular in American casinos after the World Series of Poker (WSOP) began, in 1970. Poker's popularity experienced an unprecedented spike at the beginning of the 21st century, largely because of the introduction of online poker and hole-card cameras, which turned the game into a spectator sport. In 2009 the International Federation of Poker was founded in Lausanne, Switzerland, becoming the official governing body for poker. Collectible card games or trading card games while bearing similarities to earlier games in concept, first achieved wide popularity in the 1990s. The first trading card game was 'The Base Ball Card Game' produced by The Allegheny Card Co. and registered on 4 April 1904. It featured 104 unique baseball cards with individual player attributes printed on the cards enabling each collector to build a team and play the game against another person.

After the stunning Prussian victories against Austria and France in the 19th century, the Austrians, French, British, Italians, Japanese and Russians all began to make use of wargaming as a training tool. By 1889 wargaming was firmly embedded in the culture of the U.S. Navy. The first non-military wargame rules were developed by Naval enthusiast and analyst Fred T. Jane in 1898. H. G. Wells published rules in his Floor Games (1911) and Little Wars (1913) designed for wargaming with toy soldiers. In 1956, Jack Scruby, known as the "Father of Modern Miniature Wargaming" organized the first miniatures convention and he was also a manufacturer of military miniatures and
