Checkers, also known as draughts, is a group of strategy board games for two players which involve forward movements of uniform game pieces and mandatory captures by jumping over opponent pieces. Checkers is developed from alquerque. The term "checkers" derives from the checkered board which the game is played on, whereas "draughts" derives from the verb "to draw" or "to move".

Martian Chess is an abstract strategy game for two or four players invented by Andrew Looney in 1999. It is played with Icehouse pyramids on a chessboard.

Entropy is an abstract strategy board game for two players designed by Eric Solomon in 1977. The game is "based on the eternal conflict in the universe between order and chaos [...] One player is Order, the other Chaos. Order is trying to make patterns vertically and horizontally. Chaos is trying to prevent this." The game originally employed a 5×5 gameboard, but in 2000 a 7x7 board was introduced to allow deeper strategies.

The World Trade Fair of 1900 in Paris exhibited a Salta board made of mahogany with golden counters adorned with more than 5,000 diamonds. Famous players were the US chess master Frank Marshall, the German World Chess Champion Emanuel Lasker, and the French actress Sarah Bernhardt.
A connection game is a type of abstract strategy game in which players attempt to complete a specific type of connection with their pieces. This could involve forming a path between two or more endpoints, completing a closed loop, or connecting all of one's pieces so they are adjacent to each other. Connection games typically have simple rules, but complex strategies. They have minimal components and may be played as board games, computer games, or even paper-and-pencil games.
Emergo is an abstract strategy game created by Christian Freeling and Ed van Zon in 1986. It belongs to the "stacking" category of games, or column checkers, along with Bashni and Lasca. The name comes from the motto of the Dutch province of Zeeland: Luctor et emergo meaning: "I wrestle and emerge". The goal of the game is to capture all of the opponents pieces similar to checkers/draughts. Emergo, and all column checkers, differ from most draughts variants because of their unique method of capture. A opponent's piece is added to the capturing player's column rather than being removed. Men can be recaptured from an opponent later on in the game.
Millennium 3D chess is a three-dimensional chess variant created by William L. d'Agostino in 2001. It employs three vertically stacked 8×8 boards, with each player controlling a standard set of chess pieces. The inventor describes his objective as "extending the traditional chess game into a multilevel environment without distorting the basic game."

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.
Hostage chess is a chess variant invented by John A. Leslie in 1997. Captured pieces are not eliminated from the game but can reenter active play through drops, similar to shogi. Unlike shogi, the piece a player may drop is one of their own pieces previously captured by the opponent. In exchange, the player returns a previously captured enemy piece which the opponent may drop on a future turn. This is the characteristic feature of the game.
Sygo is a two player abstract strategy game created in 2010 by Christian Freeling. It is a variant of Go. Sygo is played on a 19x19 grid of lines. It differs from Go in that captured stones change colors instead of being removed from the board, similar to Reversi/Othello. Additionally, each turn, players may either place a new stone, or else grow all of their existing groups of stones by placing a new stone adjacent to each group, similar to Symple, another of Christian Freeling's games. The goal of Sygo is to control the most territory on the board as determined by the number of a player's stones on the board as well as empty points surrounded by the players stones. The game ends either when one player resigns or both players pass on successive turns.
