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.
Sunjang baduk
Sunjang baduk (Korean: 순장바둑) is a variant of the game go (known as "baduk" in Korean) played in Korea which dates to the 16th century. It became obscure in the 1950s when it was largely replaced by modern go due to Japanese influence. There are around 45 surviving game records of Sunjang baduk, mostly from the 1880s. The oldest known game record was published in the "Chosun Ilbo" newspaper on March 1937, although the game was played much earlier. The game is between No Sa-ch'o and Ch'ae Keuk-mun. Sunjang baduk is played on a 19x19 board with 17 marked points which are used as indicators. The first 16 stones are put in a preset pattern on the marked points and black must make their first move on the Tengen (the center point on the board). Due to the prescribed nature of the opening, games tend to be aggressive which leads to fierce middle game fighting.
