According to H. J. R. Murray, the giraffe appears as a (1,4) leaper in Grant Acedrex; however, other sources describe a (2,3) movement pattern, similar to the zebra. [2]
Baroque chess is a chess variant invented in 1962 by Robert Abbott. In 1963, at the suggestion of his publisher, he changed the name to Ultima, by which name it is also known. Abbott later considered his invention flawed and suggested amendments to the rules, but these suggestions have been substantially ignored by the gaming community, which continues to play by the 1962 rules. Since the rules for Baroque were first laid down in 1962, some regional variation has arisen, causing the game to diverge from Ultima.
Chaturanga is an ancient Indian strategy board game. It is first known from India around the seventh century CE, but its roots may date 5000 years back, to the Indus Valley Civilization.
A fairy chess piece, variant chess piece, unorthodox chess piece, or heterodox chess piece is a chess piece not used in conventional chess but incorporated into certain chess variants and some chess problems. Compared to conventional pieces, fairy pieces vary mostly in the way they move, but they may also follow special rules for capturing, promotions, etc. Because of the distributed and uncoordinated nature of unorthodox chess development, the same piece can have different names, and different pieces can have the same name in various contexts as it can be noted in the list of fairy chess pieces.
The Topper Book was a comic book published from 1954 to 1994, to tie in with the children's comic The Topper. The first twelve editions were undated, and later books were published with the date of the following year on the cover, since they were traditionally published in the autumn and in time for Christmas.
Sittuyin, also known as Burmese chess, is a strategy board game created in Myanmar. It is a direct offspring of the Indian game of chaturanga, which arrived in Myanmar in the 8th century thus it is part of the same family of games such as chess, and shogi. Sit is the modern Burmese word for "army" or "war"; the word sittuyin can be translated as "representation of the four characteristics of army"—chariot, elephant, cavalry and infantry.
Tamerlane chess is a medieval chess variant. Like modern chess, it is derived from shatranj. It was developed in Central Asia during the reign of Emperor Timur, and its invention is also attributed to him. Because Tamerlane chess is a larger variant of chaturanga, it is also called Shatranj Al-Kabir, as opposed to Shatranj as-saghir. Although the game is similar to modern chess, it is distinctive in that there are varieties of pawn, each of which promotes in its own way.
The longest uncrossedknight's path is a mathematical problem involving a knight on the standard 8×8 chessboard or, more generally, on a square n×n board. The problem is to find the longest path the knight can take on the given board, such that the path does not intersect itself. A further distinction can be made between a closed path, which ends on the same field as where it begins, and an open path, which ends on a different field from where it begins.
Camelot is a strategy board game for two players. It was invented by George S. Parker late in the 19th century, and was one of the first games published by Parker Brothers, originally under the name Chivalry.
Omega Chess is a commercial chess variant designed and released in 1992 by Daniel MacDonald. The game is played on a 10×10 board with four extra squares, each added diagonally adjacent to the corner squares.

Courier chess is a chess variant that dates from the 12th century and was popular for at least 600 years. It was a part of the slow evolution towards modern chess from Medieval Chess.
The wazir or vazir is a fairy chess piece that may move a single square vertically or horizontally. In notation, it is given the symbol W. In this article, the wazir is represented by an inverted rook.
Masonic chess is a chess variant invented by George R. Dekle Sr. in 1983. The game is played on a modified chessboard whereby even-numbered ranks are indented to the right—resembling masonry brickwork. The moves of the pieces are adapted to the new geometry; in other respects the game is the same as chess.
Cross chess is a chess variant invented by George R. Dekle Sr. in 1982. The game is played on a board comprising 61 cross-shaped cells, with players each having an extra rook, knight, and pawn in addition to the standard number of chess pieces. Pieces move in the context of a gameboard with hexagonal cells, but Cross chess has its own definition of ranks and diagonals.
Quatrochess is a chess variant for four players invented by George R. Dekle Sr. in 1986. It is played on a square 14×14 board that excludes the four central squares. Each player controls a standard set of sixteen chess pieces, and additionally nine fairy pieces. The game can be played in partnership or all-versus-all.
Congo is a chess variant invented by Demian Freeling in 1982 when he was nearly 8 years old. His father encouraged him to design a variant using a 7×7 gameboard. Demian was already familiar with chess and xiangqi, and the result blends some features from both. Congo became the second-most popular chess variant at the Fanaat games club in Enschede, the Netherlands.
The camel or long knight is a fairy chess piece with an elongated knight move. It can jump three squares horizontally and one square vertically or three squares vertically and one square horizontally, regardless of intervening pieces. Therefore, it is a (1,3)-leaper.
The zebra is a fairy chess piece that moves like a stretched knight. It jumps three squares horizontally and two squares vertically or three squares vertically and two squares horizontally, regardless of intervening pieces; thus, it is a (2,3)-leaper. A lame zebra, which moves one step orthogonally and then two steps diagonally outwards and can be blocked by intervening pieces, appears as the elephant in janggi.
Betza's funny notation, also referred to as Betza notation, is a compact method to describe the way pieces move in chess-like board games. It is in common use in the world of chess variants. It was originally invented by the American chess master Ralph Betza. There have been several proposals for its extension to games with more complex moves than the original system could handle. Betza notation is used in the XBoard graphical interface for chess-like games, where it can be used to configure the move generator used for highlighting possible moves, and preventing entry of illegal ones. It is more used to write down how a piece moves, rather than the actual notation for the piece. This can be a helpful shorthand for very large chess or especially shogi variants with various types of pieces.
Grant Acedrex is a medieval chess variant dating back to the time of King Alfonso X of Castile. It appears in the Libro de los Juegos of 1283.
5D Chess with Multiverse Time Travel is a 2020 chess variant video game released for Microsoft Windows, macOS, and Linux by American studio Thunkspace.
