Entertainment
Equipment varies with the game. Board games, such as Go, "Monopoly" or backgammon need a board and markers. One of the oldest known board games is Senet, a game played in Ancient Egypt, enjoyed by the pharaoh Tutankhamun. Card games, such as whist, poker and Bridge have long been played as evening entertainment among friends. For these games, all that is needed is a deck of playing cards. Other games, such as bingo, played with numerous strangers, have been organised to involve the participation of non-players via gambling. Many are geared for children, and can be played outdoors, including hopscotch, hide and seek, or Blind man's bluff. The list of ball games is quite extensive. It includes, for example, croquet, lawn bowling and paintball as well as many sports using various forms of balls. The options cater to a wide range of skill and fitness levels. Physical games can develop agility and competence in motor skills. Number games such as Sudoku and puzzle games like the Rubik's cube can develop mental prowess.
History of games
First patented in 1904, "The Landlord's Game", designed by Elizabeth Magie, was originally intended to illustrate the economic consequences of Ricardo's Law of Economic rent and the Georgist concept of a single tax on land value. A series of board games were developed from 1906 through the 1930s that involved the buying and selling of land and the development of that land. By 1933, a board game had been created much like the version of modern Monopoly by the Parker Brothers. 
Though the first commercial version of the game of Battleship was "Salvo", published in 1931 in the United States by the Starex company, the game itself dates to before World War I when it was played on paper by Russian officers. The French board game "L'Attaque" was first commercially released in 1910, having been designed two years prior as a military-themed imperfect knowledge game based upon the earlier Chinese children's board game Dou Shou Qi. "L'Attaque" was subsequently adapted by the Chinese into Luzhanqi (or "Lu Zhan Jun Qi"), and by Milton Bradley into Stratego, the latter having been trademarked in 1960 while the former remains in the public domain. Jury Box, published in 1935, was the first murder mystery game which served as the basis for games like Cluedo.
