9. Othello
Originally called Reversi, this strategy board game for two players originated in 1883 by an Englishman: either Lewis Waterman or John Mollett. Each one called the other a fraud, and it will perhaps never be known who was the true inventor, although it is widely assumed to be based on an earlier game, ‘Annex’, made by Mollett. The game is played with 64 identical discs, light on one side and dark on the other and the aim is to have more of your assigned shade of disc visible than your opponents, when the final playable space is filled. Over 40 million copies have been sold worldwide, and it is widely played online.
