* '''[[Balbo's Game]]''': A novel-shaped board with 70 squares. Full armies for each player, minus one pawn. No castling. By G. Balbo (1974).
* '''[[Chessence]]''': Nine pieces per player move according to their relative positions to each other on a 6×9 board with missing squares and kings immobile in the corners. By Jim Winslow (1989).
* '''[[Circular chess]]''': Played on a circular board consisting of four rings, each of sixteen squares.
* '''[[Cross chess]]''': Cross-shaped cells, board geometry like hex chess but moves akin to normal chess (e.g. bishops have four directions, not six; queens eight, not twelve). Extra rook, knight, and pawn per side. By George Dekle Sr.
* '''[[Cylinder chess]]''': Played on a cylinder board with a- and h-files "connected". Thus a player can use them as if the a-file were next to the h-file (and vice versa).
* '''[[Infinite chess]]''': Numerous players and mathematicians have conceived of chess variations played on an unbounded chessboard.<ref name="PBS"/> In one example, when using "Converse's rules," the pieces and their relative starting positions are unchanged—only the board is infinitely large.<ref name="IC">[http://www.chessvariants.com/boardrules.dir/infinite.html Infinite Chess] {{Webarchive|url=https://web.archive.org/web/20170402082426/http://www.chessvariants.com/boardrules.dir/infinite.html |date=2017-04-02 }} at ''The Chess Variant Pages''. An infinite chess scheme represented using ASCII characters.</ref>
* '''[[Masonic Chess]]''': Every other board rank is indented. Same as chess, with moves adapted to the new brickwork-like board. By George Dekle Sr.
* '''[[Omega chess]]''': On a 10×10 board with four extra squares, one per corner. Includes the champion and wizard fairy pieces. Both are leapers, with different ways of leaping.
* '''[[Rhombic Chess]]''': Uses a hex-shaped board comprising 72 rhombus cells. Normal set of chess pieces move ''edgewise'' or ''pointwise''. Checkmate objective as usual. By Tony Paletta (1980).
* '''[[Rollerball (chess variant)|Rollerball]]''': Inspired by the sci-fi film of the same name, pieces move clockwise around a Roller Derby-like track. By Jean-Louis Cazaux (1998).
* '''[[Spherical chess]]''' [multivariant]: A family of variants played on a chessboard wrapped around a sphere. The a- and h-files are adjacent. The poles are circular or octagonal and may or may not be occupied according to the variant. There are no board edges, so kings always have eight adjacent squares. Trans-polar diagonal moves mostly differentiate between variants.{{sfnp|Pritchard|2007|p=223|ps=}}{{sfnp|Pritchard|1994|pp=285–86|ps=}}
*'''Thrones Chess''':{{citation needed|date=July 2023|reason=Current citation is a dead link.}} Uses a board that combines a circular component and a square component, which allows long-range pieces to attack from three sides. The board is divided into two castles and a battlefield. A piece cannot cross more than two castle walls in the same move, and a king in check may not leave a castle except to capture the piece giving check. Knights have additional non-capturing moves. By Richard Van de Venter (1999). [[File:Thrones Chess initial setup.png|alt=|thumb|Thrones Chess, initial setup with the classic chess pieces. Free squares may be filled by additional classic or fairy chess pieces.]]
* '''Zonal chess''': Board has triangular wings or "zones" on either side of the main 8×8 board. Queens, bishops, and rooks that start from one of the squares in either zone may change direction and keep going on the same move. A queen, for example, could zig around an obstruction and attack a piece in the opposite zone. The power to change direction only applies when a piece's move starts from a zonal area. It is possible (using the queen and rook) to cross the board from one zone to another, but any piece entering a zone cannot make use of the extended move.<ref>[http://www.chessvariants.org/shape.dir/zonal/zonal.html "Zonal Chess"] {{Webarchive|url=https://web.archive.org/web/20060306034211/http://www.chessvariants.org/shape.dir/zonal/zonal.html |date=2006-03-06 }} by Larry Smith, ''[[The Chess Variant Pages]]''</ref>
