Triangulation is an extra challenging 3-Army Chess Variant for 2 or 3 players. In this strategic battle, a player melees to capture the opponent’s General(s) while avoiding capture. The Game is played on a triangular board with 64 black and white triangles. Triangulation employs the ancient Indian strategy game Chaturanga designations, which utilizes army divisions labelled as Infantry, Cavalry, Chariotry (also known as a Rukh in
Persian chess), General, Elephantry, and King. These playing pieces became, respectively, the Pawn, Knight, Rook, Queen, Bishop, and King in the Middle Ages in the popular game of Chess as we know it today.

Triangulation is played on triangles instead of squares to simplify the direction of each player’s movement. There are a total of 27 playing pieces divided into 3 sets, 1 set for each army. Each set has 9 playing pieces consisting of 1 General, 1 Cavalry, 2 Rukhs, and 5 Infantry. Each of the 4 different pieces of each player moves in distinctive ways, somewhat similar to the corresponding pieces in chess. Each army is represented by the different colours Red, Green, and Blue.

A round of play consists of the Red player making the first move, followed by the Green player, with the Blue player making the third and final move. This sequence of moves continues until only 1 General remains or a Draw is called. When one player captures one of the other player’s Generals, the remaining captured army becomes allies for the capturing player.
