QUARTO VS SHATAR

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.

Shatar (Mongolian: ᠮᠣᠩᠭᠣᠯ ᠰᠢᠲᠠᠷ᠎ᠠ Monggol sitar-a, "Mongolian shatranj"; a.k.a. shatar) and hiashatar are two chess variants played in Mongolia. The rules are similar to standard chess; the differences being that: The noyan (ᠨᠣᠶᠠᠨ, lord) does not castle. The küü (ᠬᠦᠦ, pawn) does not have an initial double-step move option, except for the queen pawn or king pawn. In old shatar rules, a pawn that reaches its eighth rank must promote to half-power tiger. But a pawn could step back to its sixth rank to promote to all-power tiger. It moves like a queen. The baras (ᠪᠠᠷᠰ or ᠪᠠᠷᠠᠰ, tiger; Persian: fers) moves like a promoted rook in shogi: like a chess rook or one square diagonally. It was called half-power tiger or half-power lion in old shatar rules. In modern shatar rules, a baras moves like a queen. The mori (knight; ᠮᠣᠷᠢ) cannot deliver mate. In modern shatar rules, the mori can give mate. The bishop (teme) and rook (terge) move as they do in standard chess. The game always starts by White playing 1.d4 and Black responding with 1...d5. This is the only time in the game a pawn may advance two squares; some sources claim this initial move can optionally be made with the e-pawn. In old shatar rules, Ujimqin player must make an initial double-step move with the queen pawn; in Chahar, the king pawn. In old shatar rules, baremate is draw. In old shatar rules, one special rule is called tuuxəi, like komi in Go. A player could leave the enemy with only two pieces remaining (noyan and another piece) at the end. Then he must start making checks using the terge or baras and make consecutive checks until checkmate. Before checkmate, number of consecutive checks is the number of tuuxəi. If a player wins by checkmate as in chess, he receives only one tuuxəi. A player usually leaves the enemy with one noyan and one küü to allow time to put his pieces into good positions for making consecutive checks.
