Chaos is a strategy game similar to chess. Each side has a 27 piece army consisting of 15 different character types. In the Intermediate Game the pieces have special abilities on yellow power squares. This allows for more sophisticated strategies than in the basic game.

It is recommended that you become familiar with all of the piece movements in the Basic Game before playing the Intermediate Game. In the Intermediate Game pieces have additional abilities on yellow power squares. There are also some new promotion rules (see Captain).

The pieces:

• Foot Soldier: Moves just like a pawn in chess. Promotes to a captain in the back row. May capture forward while on a yellow power square or while a captain occupies a yellow power square.
• Captain: Moves one or two spaces orthogonally. Captures one or two spaces forward or one space diagonally forward. Promotes to an angel, serpent, elf or mage on the back row power square. If another piece is on the back row power square, then a captain may promote the piece by moving into it. A mage promotes to an archmage, a serpent promotes to a dragon, an angel promotes to an archangel, an elf promotes to an elven archer, and a captain promotes to a berserker, golem, sorceress or spirit. While a captain occupies a yellow power square all friendly foot soldiers may capture forward.
• Elf: Moves like a rook in chess. May fire like an elven archer while occupying a yellow power square.
• Angel: Moves like a knight in chess. When landing on a yellow power square may sacrifice itself for a piece which has been captured but not destroyed.
• Serpent: Moves like a bishop in chess. May move like a dragon while occupying a yellow power square.
• Mage: Moves like a queen in chess, but may not capture on a void (red) square. May teleport to any yellow power square upon reaching a yellow power square or while on a yellow power square.
• Elven Archer: Moves or fires like a rook. May fire immediately when landing on a yellow power square. Destroys pieces when firing from a yellow power square.
• Archangel: Moves like a knight or may double this movement. When landing on a yellow power square it may sacrifice itself for a piece which has been captured but not destroyed.
• Archmage: Moves like a rook followed by a bishop, or a bishop followed by a rook. May not capture on a void (red) square. May teleport to any yellow power square upon reaching a yellow power square or while on a yellow power square.
• Berserker: Moves one square orthogonally or like a bishop. Destroys any number of pieces diagonally (friendly or enemy). When landing on a yellow power square destroys all pieces (friendly or enemy) in adjacent squares.
• Emperor: Moves like a king in chess.
• Dragon: Moves like a queen in chess. May pass over friendly pieces. While occupying a yellow power square can only move as a serpent.
• Spirit: Moves three spaces freely. Moves four spaces from a yellow power square.
• Sorceress: Interchanges with any friendly piece not occupying a void (red) square. While occupying a yellow power square may interchange with all enemy pieces (except an emperor) not occupying a void square.
• Golem: Moves one space in any direction. Destroys all pieces in adjacent squares. Any piece landing on a golem occupying a yellow power square is destroyed.
