BACKGAMMON VS HIJARA

Backgammon is one of the oldest known board games. Its history can be traced back nearly 5,000 years to archaeological discoveries in Mesopotamia. It is a two-player game where each player has fifteen pieces (checkers or men) that move between twenty-four triangles (points) according to the roll of two dice. The objective of the game is to be first to bear off, i.e. move all fifteen checkers off the board. Backgammon is a member of the tables family, one of the oldest classes of board games. Backgammon involves a combination of strategy and luck (from rolling dice). While the dice may determine the outcome of a single game, the better player will accumulate the better record over a series of many games. With each roll of the dice, players must choose from numerous options for moving their checkers and anticipate possible counter-moves by the opponent. The optional use of a doubling cube allows players to raise the stakes during the game. Like chess, backgammon has been studied with great interest by computer scientists. Owing to this research, backgammon software such as TD-Gammon has been developed that is capable of beating world-class human players.

Hijara is a two-player abstract strategy board game played with small stones. It has been likened to a three-dimensional game on a two-dimensional board. The game was designed by Martin H. Samue| and first printed, as Excel, by American Airlines in their inflight magazine, American Way, on December 24, 1985 and July 22, 1986. It has been sold commercially as Eclipse in 1994, and Hijara (the Arabic word for small stones) in 1995, 2003 and 2006. The original commercial edition of Hijara has a game board of 16 squares, divided into 4 sections numbered 1 through 4 and a score-keeping "ladder" on either end. Players choose either yellow or blue and use 32 same-color stones plus one score-keeper each. Blue starts and players take turns placing their stones, one at a time, on any square, building on those already on the board, to complete and block point-scoring combinations. When a player places a stone on a square, it must be placed in the lowest-numbered open section in that square. So, for every square, the first small stone must be placed on the 1, second on the 2, etc. The game starts with an empty board, and ends with a full board with 3 ways to score points when placement of four same-color stones is completed in any of the following combinations: 10 points - 4 stones of the same color on 4 numbers of a kind in a row - horizontally, vertically, or diagonally. 15 points - 4 stones of the same color in numerical sequence (i.e. 1-2-3-4) - horizontally, vertically, or diagonally. 20 points - 4 stones of the same color in one square. Points are won with a player's own-color stones and are always accrued, never deducted. Several point-scoring combinations may be completed at one time with a single stone. Overlooked points are forfeited and, throughout the game, players keep score on their side of the board with an extra stone of their color. The game is over when the last small stone is placed and all the numbers are covered then, by comparing accrued points totals, the player with the greater number of points is the winner of the game.
