Senet
Senet is one of the oldest known board games. Fragmentary boards that could be senet have been found in First Dynasty burials in Egypt, c. 3100 BC. A hieroglyph resembling a senet board appears in the tomb of Merknera (3300–2700 BC). The first unequivocal painting of this ancient game is from the Third Dynasty tomb of Hesy (c. 2686–2613 BC). People are depicted playing senet in a painting in the tomb of Rashepes, as well as from other tombs of the Fifth and Sixth Dynasties (c. 2500 BC). The oldest intact senet boards date to the Middle Kingdom, but graffiti on Fifth and Sixth Dynasty monuments could date as early as the Old Kingdom.
At least by the time of the New Kingdom in Egypt (1550–1077 BC), senet was conceived as a representation of the journey of the ka (the vital spark) to the afterlife. This connection is made in the Great Game Text, which appears in a number of papyri, as well as the appearance of markings of religious significance on senet boards themselves. The game is also referred to in chapter XVII of the "Book of the Dead".
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.
