HIJARA VS QUARTO

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.

Quarto is a board game for two players invented by Swiss mathematician Blaise Müller. It is published and copyrighted by Gigamic. The game is played on a 4×4 board. There are 16 unique pieces to play with, each of which is either: tall or short; red or blue (or a different pair of colors, e.g. light- or dark-stained wood); square or circular; and hollow-top or solid-top. Players take turns choosing a piece which the other player must then place on the board. A player wins by placing a piece on the board which forms a horizontal, vertical, or diagonal row of four pieces, all of which have a common attribute (all short, all circular, etc.). A variant rule included in many editions gives a second way to win by placing four matching pieces in a 2×2 square. Quarto is distinctive in that there is only one set of common pieces, rather than a set for one player and a different set for the other. It is therefore an impartial game.
