Why is it called Othello?

The short answer

The game is named after Shakespeare's play Othello. The name was chosen by Shiro Hasegawa, an English literature scholar and the father of Goro Hasegawa, who created the game. The play follows a black general and his white wife while friends and enemies keep switching sides, which is what black and white discs do on the board.

Othello and Reversi are the same game. Reversi is the older English name. Othello is the name the game was given when it was relaunched in Japan in the 1970s, and it came from a Shakespeare play by way of a professor of English.

The play behind the name

Othello is one of Shakespeare's tragedies. Its hero is Othello, a black Moorish general serving Venice, who marries Desdemona, a white Venetian woman. Over the play, his officer Iago turns him against her, and loyalties flip back and forth until it ends in disaster.

MegaHouse, the company that owns the Othello trademark, describes the naming in exactly those terms: a black general and a white wife at the centre of a story where friend and foe keep changing sides, matched to a game where black and white discs turn over and the lead keeps changing hands.

Every Othello game starts the same way: two black discs, two white, on a green board. After that, every disc on the board can change sides.

Who picked it

Goro Hasegawa developed the game in Mito, Japan, and registered it under the name Othello in 1971. The name itself came from his father, Shiro Hasegawa, a scholar of English literature. Both MegaHouse and the city of Mito credit Shiro with the name. More on Goro Hasegawa, and who invented the game.

Why the board is green

The same idea runs through the equipment. The green board is said to stand for the green plain where the battle in the play takes place. The city of Mito gives this explanation, and English Wikipedia says the same. The discs are black on one face and white on the other, so every disc on the board is one flip away from changing sides.
