Rules of Reversi
The aim is to finish the game with more pieces in your colour than in your opponent's colour.
Place a piece on the board next to one in your opponent's colour so that one or more discs in your opponent's colour are enclosed horizontally, vertically or diagonally by pieces in your colour. These enclosed pieces are turned into your colour.
Black always moves first.
If one player cannot place a counter their move is forfeited.
The game ends when either all the squares are covered or neither player can move. At this point the winner will be the player with the most discs in their colour.
