Scotland Yard is a board game in which a team of players, as police, cooperate to track down a player controlling a criminal around a board representing the streets of London.
 It is named after Scotland Yard, the headquarters of London's Metropolitan Police Service.
 "Scotland Yard" is an asymmetric board game, with the detective players cooperatively solving a variant of the pursuit-evasion problem.
 The game is published by Ravensburger in most of Europe and Canada and by Milton Bradley in the United States.
 It received the "Spiel des Jahres" (Game of the Year) award in 1983.
David Wesely (born March 16, 1945) is a wargamer, board game designer, and video game developer.
 Dave Arneson credited him with the idea of the role-playing game.
Buga-shadara, also known as Bouge Shodre, is a two-player abstract strategy board game from Tuva, a republic in Siberia, Russia.
 It is a hunt game where one player plays the deers (which is "buga" in the Tuva language).
 There are two deers usually represented as the black pieces.
 The boars are also referred black in the referenced article "Buga-shadara a folk game from Tuva".
 The other player has 24 white pieces with dogs associated to them.
 The board consist of an Alquerque board flanked on two of its opposite sides by a square patterned board (referred to as "side-houses" in the referenced article).
 Because the board is in part an Alquerque board, this makes Buga-shadara a tiger hunt game (or tiger game).
 What makes Buga-shadara unique among tiger games are the expansion boards on the two opposite sides of the Alquerque board.
 They are square, whereas most are triangle-like.
 The word "shadara" resembles the word "shahdara".
 The "shah" part "is a title given to the emperors/kings and lords of Iran (historically also known as Persia)."
.
 There is a place called Shahdara Bagh in Lahore, Punjab, Pakistan, and it's thought that the word "Shahdara can be translated as "the way of kings".
 Shah translates as "king" and dara translates as the way of kings."
 The referenced article associates the boars (the two black pieces) as kings.
 Perhaps the boars or deers are kings, and have to find a way or have a way with the white pieces or dogs.
Cheyenne Game (1958) is a Milton Bradley children's board game for two to four players based on the 1957 Golden Globe Award winning ABC Warner Bros. western television series "Cheyenne" (1955-1962) starring Clint Walker.
 The game is a typical track/racing board game.
 A second edition of the game was released during Clint Walker's dispute with Warner Bros. that featured "Bronco" star Ty Hardin on the box cover.
 "Cheyenne" was one of many board games published during the 1950s based on television programs.
Pasang is a two-player abstract strategy board game from Brunei.
 The game is often referred to as Pasang Emas which is actually a software implementation of the traditional board game.
 The object of this game is to acquire the most points by capturing black and white tokens on the board.
 Black tokens are worth 1 point, and white tokens are worth 2 points.
 The board is initially laid out with all 120 black and white tokens in one of over 30 traditional patterns.
 Players choose a piece called a "ka" which is used to capture the tokens on the board.
 Each player's "ka" moves around the board capturing as many tokens as possible.
 As a note, the "kas" are the only mobile pieces in the game.
 The other pieces are stationary, and are captured by the "kas".
 Players must capture token(s) during their turn, or lose the game.
 When all tokens have been captured from the board, the player with the most points is the winner.
 However, if there are any tokens left on the board, and none can be captured on a player's turn, then that player loses the game, and the other player is the winner.
Evo: The Last Gasp of the Dinosaurs is a German-style board game for three to five players, designed by Philippe Keyaerts and published by Eurogames.
 The game won the "GAMES Magazine" award for "Game of the year 2002" and was nominated for the Origins Award for "Best Graphic Presentation of a Board Game 2000".
 The game went out of print in 2007, and a second edition was released in 2011.
Awithlaknannai Mosona is a two-player strategy board game from the Zuni Native American Indian tribe of New Mexico, United States.
 It is unknown how old the game is.
 The game was described by Stewart Culin in his book "Games of the North American Indians Volume 2: Games of Skill" (1907).
 In this book, it was named Awithlaknan Mosona.
 Awithlaknannai Mosona resembles another Zuni board game called Kolowis Awithlaknannai (Fighting Serpents) with few minor differences.
 The former having a smaller board, and depending upon the variant, it also has less lines joining the intersection points.
 The rules are the same.
 Awithlaknannai Mosona belongs to the draughts and Alquerque family of games as pieces hop over one another when capturing.
 It is actually more related to Alquerque, since the board is made up of intersection points and lines connecting them.
 It is thought that the Spanish had brought Alquerque to the American Southwest, and Awithlaknannai Mosona may have been an evolution from Alquerque.
 However, in Stewart Culin's 1907 book, the Zunis claim that they had adopted a hunt game from Mexico similar to Catch the Hare and the Fox games of Europe, and transformed it into Awithlaknannai Mosona.
 In these games, one player has more pieces over the other, however, the other player's piece has more powers.
 The Zuni's equalized the numbers of pieces and their powers, and also may have transformed the board making its length far exceed its width.
 Diagonal lines also replaced orthogonal lines altogether.
 However, the hunt game from Mexico may have used an Alquerque board even though the game mechanics of their new game, Awithlaknannai Mosona, were completely different.
Komikan (from the Mapuche kom ikan "to eat all") is a two-player abstract strategy board game of the Mapuches (known by the Spaniards as the Araucanians) from Chile and Argentina.
 The same game is also played by the Incas under the name Taptana, Komina, Comina, Cumi, Puma, or Inca Chess.
 In modern Quechua, the language of the ethnolinguistic group that are the descendants of the Incas, Taptana means "chess".
 It is known by the Aymaras, a neighboring ethnolinguistic group to the Quechuan people, as kumisiña.
 Throughout South America the game is known as El león y las ovejas which literally means "the lion and the sheep".
 The lion is actually a puma as there are no lions native to the Americas.
 The Mapuches also call it El Leoncito.
 J. I. Molina, in 1787, described it as ‘"el artificioso juego del ajedrez, al cual dan el nombre de comican"’ which translates to ""the ingenious game of chess to which they (the Mapuche) give the name comican"".
 Komikan may actually be the same game as Adugo (Jaguar and Dogs) as played by the Bororó people of Brazil.
 in 1898, Stewart Culin, the famed anthropologist, named a game played in Peru as Solitario.
 The same name was also used by the game historian, Murray, in 1952.
 The game may also be known in Peru as Kukuli.
 Komikan is a hunt game, and specifically a tiger hunt game (or tiger game) since it uses an expanded Alquerque board.
 Like all hunt games, there are two unequal forces at play.
 In Komikan, one player has only a single piece, usually called a "puma" or "jaguar", or ""kom ikelu"" (in Mapuche language "the one which eats all"), or "leon" (Spanish for lion), which can move one space at a time or capture the other player's pieces by hopping over them.
 The other player has twelve pieces (usually called a "sheep" or "goat" or "dogs"), or perros or perritos which is Spanish for "dogs" and "little dogs" respectively, that can only move one space at a time, but not capture, and attempts only to surround and immobilize the puma or jaguar.
 Pieces must move and/or capture following the pattern on the board.
 The expanded Alquerque board consist of an Alquerque board and a triangular patterned board attached on one of its side.
