Epaminondas is a strategy board game invented by Robert Abbott in 1975. The game is named after the Theban general Epaminondas, known for the use of phalanx strategy in combat. The concept of the phalanx is integral to the game.

Contents

Epaminondas was originally introduced in Sid Sackson's A Gamut of Games as Crossings . While the original version used an 8×8 checkerboard, the current game uses a 12×14 board and different rules for capture. When published, it claimed to be one of the first modern games to acknowledge the name of its inventor in its rules.

Phalanx

In the game, a phalanx is a horizontal, vertical, or diagonal line of two or more stones of the same color, with no empty spaces or enemy stones between them. A stone may belong to more than one phalanx, depending on the direction considered.

Rules

Moves

White moves first; then turns alternate.

Captures

Only phalanxes can make captures. Capturing is never compulsory. The head piece of a phalanx may land on an enemy stone if the number of the following opponent's stones, in the direction of the phalanx movement and including the stone directly hit, is strictly smaller than the number of stones in the moving phalanx. In that case, those opponent's stones are captured. This means, a phalanx of length n may capture up to n-1 stones.

Winning

A player wins when, at the start of their turn, they have strictly more pieces on their opponent's home row than the opponent has on the player's home row. (To clarify, if at the beginning of Black's turn, Black has more pieces on row A than White has on row Z, Black wins. If at the beginning of White's turn, White has more pieces on row Z than Black has on row A, White wins.) This allows an opponent the chance to capture some of the offending stones on the turn after an incursion, or to counterattack on the opposite side of the board.

Reception

Games magazine included Epaminondas in their "Top 100 Games of 1980", noting that "It comes in a beautiful edition that makes watching the shifting board position all the more enjoyable." [1]

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.
