Official Rules

Introduction

Football Chess combines the strategic depth of chess with the excitement of American football. This rulebook outlines the complete set of official rules and serves as a reference document for players.

Game Overview

Football Chess is played on a standard 8×8 chess board that represents a football field. Players control chess pieces that move according to standard chess rules while attempting to advance the football toward the opponent's end zone to score touchdowns. The player with the most points at the end of the game wins.

Game Components

  • Chess Board: Standard 8×8 grid with alternating light and dark squares
  • Chess Pieces: Each player has a set of chess pieces (pawns, knights, bishops, rooks, queen, and king)
  • Football: A special token that can be carried by pieces or thrown across the board
  • Scrimmage Line: A visual indicator showing the line where the ball was last controlled
  • Yard Markers: Indicators for yard lines on the field

Game Setup

  1. The board is oriented with end zones on the left and right sides
  2. Each player starts with standard chess pieces arranged in formation along their respective ends of the board
  3. White pieces start on the right side of the board, black pieces on the left
  4. The ball starts at the center of the board on the middle line (4th rank)
  5. The scrimmage line is initially set at the center of the board (4th file)

Game Flow

Phases

The game consists of multiple possessions, each with the following phases:

  1. Formation Phase: Players arrange their pieces in legal formations behind their line of scrimmage
  2. Action Phase: Players take turns moving one piece at a time, carrying or throwing the ball and attempting to score

Turn Sequence

On your turn, you must perform one of the following actions:

  1. Move a piece according to standard chess rules
  2. Move a piece carrying the ball according to standard chess rules
  3. Throw the ball using a direct or indirect throw (if your piece has possession of the ball)

Movement Rules

  • All pieces move according to standard chess rules, with additional football-specific actions
  • Pieces can move through squares occupied by friendly pieces during the Formation Phase only
  • During the Action Phase, pieces cannot move through occupied squares
  • A piece carrying the ball follows the same movement rules as a normal piece of its type
  • Moving a piece onto a square with the ball results in that piece gaining possession of the ball

Ball Mechanics

Possession

  • A piece gains possession of the ball by moving onto the square containing the ball
  • Only one piece can possess the ball at a time
  • A piece in possession of the ball is marked visually on the board

Throw Mechanics

There are two types of throws:

  1. Direct Throw:

    • The ball travels in a straight line (horizontally, vertically, or diagonally)
    • The throw continues until it reaches the first piece in its path or the edge of the board
    • If the first piece in the path is friendly, that piece gains possession
    • If the first piece in the path is an opponent's, a fumble occurs

  2. Indirect Throw:

    • The ball follows a non-linear path, similar to a knight's move in chess
    • The throw consists of two squares in one direction followed by one square perpendicular
    • The ball lands on the target square regardless of pieces in between
    • If a friendly piece occupies the target square, that piece gains possession
    • If an opponent's piece occupies the target square, a fumble occurs
    • If the target square is empty, the ball remains there until a piece moves onto it

Fumble Mechanics

When a fumble occurs:

  1. The ball becomes loose and is placed on the square where the fumble occurred
  2. The turn ends immediately
  3. On the next turn, either player can attempt to gain possession by moving a piece onto the ball's square
  4. The first player to move a piece onto the ball's square gains possession

Scoring

Touchdown (6 points)

  • Scored by moving a piece carrying the ball into the opponent's end zone
  • After a touchdown, the ball is reset to the center of the board
  • The player who conceded the touchdown gets the next possession

Interception (2 points) 💡

  • Scored by intercepting an opponent's throw
  • Play continues with the intercepting player maintaining possession of the ball

Special Rules

Scrimmage Line

  • The scrimmage line is established at the file where the ball was last controlled
  • During the Formation Phase, all pieces must be positioned behind the scrimmage line
  • The scrimmage line shifts as the ball moves across the board

Capture

  • When a piece is captured, it is removed from the board according to standard chess rules
  • If a piece carrying the ball is captured, a fumble occurs at that location

King Safety

  • The king can carry and throw the ball just like any other piece
  • Putting the opponent's king in check or checkmate follows standard chess rules
  • If a king is in check, the player must resolve the check following standard chess rules before continuing with football actions

Penalties

The following actions result in penalties:

Illegal Formation (Loss of Turn)

  • Positioning pieces in front of the scrimmage line during Formation Phase
  • Having pieces on the opponent's side of the scrimmage line during Formation Phase

Illegal Movement (Move is Reversed)

  • Moving a piece in a way that doesn't follow its standard chess movement rules
  • Moving through an occupied square (except during Formation Phase)

Throwing Violation (Turnover)

  • Attempting to throw the ball without having possession
  • Throwing the ball off the board
  • Throwing to an invalid target square

Clock Violation (Loss of Turn) 💡

  • Taking too long to make a move (if playing with a timer)
  • Timer can be set before the game begins

Advanced Rules 💡

Fourth Down

  • After three consecutive possessions without scoring, the fourth down rule activates
  • On the fourth down, the player must either score or advance the ball at least two files forward
  • Failure to do so results in a turnover

Field Goal

  • As an alternative to attempting a touchdown, a player may declare a field goal attempt
  • The piece with the ball must be within a certain range of the opponent's end zone
  • Success is determined by a dice roll or other random mechanism
  • A successful field goal scores 3 points

Safety

  • If a player's piece carrying the ball is forced into their own end zone and cannot move out on their next turn, a safety is scored
  • The opponent scores 2 points, and possession changes
