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.
Penultima
Penultima is a game of inductive logic, played on a chess board. It was invented by Michael Greene and Adam Chalcraft in Cambridge in 1994. The game is derived from the chess variant Ultima (otherwise known as "Baroque chess"), and played with a standard chess board and pieces, each piece having different movement and capture rules from standard chess. In a manner similar to the game Mao, which was a popular game in Cambridge at that time, the rules for each piece vary from game to game, and are initially kept secret from the players. Penultima is similar in style to Eleusis, Zendo and Mao. The name of the game is a pun on "penultimate", and "Ultima", the name of the chess variant.
