Reversi Rules

Overview

Reversi is a two-player game where the player possessing the most pieces at the end of the game wins. You try to win by converting as many of your opponent's pieces as possible to your own color while denying your opponent the ability to convert more of your pieces.

Board

The standard Reversi board size is 8x8. Igfip™ supports a range of smaller and larger board sizes as well as rectangular boards and obstructed spaces.

Pieces

Each player starts with two pieces. Conceptually, each piece has two sides, with each side corresponding to the color of each player. When a player's piece flips, it converts to the opposing player's color.

Rules

  1. Black moves first.
  2. You may place a piece on an empty space adjacent to an opposing piece so as to form a line—orthogonally or diagonally—of contiguous opposing pieces that terminates in a bracketing friendly piece.
  3. When you place a piece in a valid space, all opposing pieces intervening between the placed piece and a bracketing friendly piece are flipped.
  4. If a player cannot move, play passes to the opposing player.
  5. If neither player can move, the game ends and the player with the most pieces remaining wins. If both players possess the same number of pieces, the result is a draw.
