Reversi is a strategy board game for two players. They compete using 64 identical game pieces that are light on one side and dark on the other. Each player chooses one colour to use throughout the game. Players take turns placing one disk on an empty square, with their assigned colour facing up. After a play is made, any disks of the opponent’s colour that lie in a straight line bounded by the one just played and another one in the current player’s colour are turned over. When all playable empty squares are filled, the player with more disks showing in their own colour wins the game. A modern version of this game was called Othello. Englishmen Lewis Waterman and John W. Mollett both claim to have invented the game of Reversi in 1883, each denouncing the other as a fraud. Some of the early Jaques sets have the name of Lewis Waterman on them credited as the inventor. This set included 66 red/black pieces and a cardboard box has a green and red label on the lid with “Lewis Waterman” as the inventor of the game.
