Abalone is a two-player abstract strategy board game designed by Michel Lalet and Laurent Lévi in 1987. Players are represented by opposing black and white marbles on a hexagonal board with the objective of pushing six of the opponent's marbles off the edge of the board. Abalone was published in 1990 and has sold more than 4.5 million units. The year it was published it received one of the first Mensa Select awards. It is currently sold in more than thirty countries. The board consists of 61 circular spaces arranged in a hexagon, five on a side. Each player has 14 marbles that rest in the spaces and are initially arranged as shown below, on the left image. The players take turns with the black marbles moving first. For each move, a player moves a straight line of one, two or three marbles of one color one space in one of six directions. The move can be either broadside / arrow-like (parallel to the line of marbles) or in-line / in a line (serial in respect to the line of marbles), as illustrated below. A player can push their opponent's marbles (a "sumito") that are in a line to their own with an in-line move only. They can only push if the pushing line has more marbles than the pushed line (three can push one or two; two can push one). Marbles must be pushed to an empty space (i.e. not blocked by a marble) or off the board. The winner is the first player to push six of the opponent's marbles off of the edge of the board.

Diamond is a two-player abstract strategy board game invented by Larry Back. The invention was inspired by the game Kensington, which uses a similar board pattern and game objective. Rules for Diamond were conceived in 1985 and finalized in 1994. Diamond introduces a new board geometry and neutral pieces, with the aim of enhancing the game dynamic and lowering the potential for draws. Diamond was featured in the February 2013 issue of Games magazine. The Diamond gameboard consists of interlocking squares and triangles. White and Black each control 12 game pieces of their own color. Neutral pieces (red-colored in the diagrams) enter the game via captures. The pieces are played on the line intersections (called points, as in Go). White and black (but not red) pieces can move along straight lines to adjacent unoccupied points. A player wins by being the first to occupy all four corners (points) of a board square with their pieces. Capturing moves are possible in the Movement phase. If the points of a triangle contain exactly one white and one black piece, either player can capture the opponent piece by occupying the remaining open point ("cornering" the enemy piece on the triangle). The captured piece can be cornered on one triangle (see Example 1), or simultaneously cornered on two different triangles (Example 4). The captured piece is immediately removed from the game and replaced on its point by a neutral piece. If a move simultaneously corners two opponent pieces on two different triangles, then neither enemy piece is captured (Examples 2 and 3). A piece can move safely to a triangle point even if the other two points of the triangle are occupied by enemy pieces (Example 5).
