Reversi is a game of controlling territory on the board. This is done by converting the other player's pieces to your own. The game was first created by Lewis Waterman in 1988, though it is similar to James Mollett's Game of Annexation (1870). In 1971 Goro Hasegawa independantly created the nearly identical game of Othello, published by Mattel.



To convert as many of the other player's pieces to your own, until no more pieces can be placed on the board. The player with the greater number of pieces on the board wins.


  • Layout
    The game is played on a 8 x 8 board, with two pieces of each player placed in the center of the board.

  • Placement
    The players alternate placing pieces on the board. Pieces may only be placed on empty squares such that there are one or more of the other player's (horizontally, vertically, or diagonally) pieces between the placed piece and another of your pieces. All of the other players pieces between your two pieces are changed to your pieces.

    Placing where the orange circle is in the following is possible because of the pieces shown with the arrows:

    and flips the intervening pieces like so:

    When there's nowhere you can place a piece on the board, you have to pass your turn. To do that, just click the Send button. The game will ask if you really want to pass your turn, just click OK. (It may ask you a second time, but if it does, click OK again.)
