Computer Othello (1978)

Computer Othello (コンピューターオセロ) is a reversi-based video arcade game developed and published by Nintendo. It is one of their earliest video arcade games along with Block Fever and after they did release a dedicated console called Color TV Game 6 and a variety of electromechanical arcade games earlier in the 1970s. It was released exclusively in Japan in 1978. Some sources  claim that Ikegami Tsushinki also did development work on Computer Othello. It is not known to have ever been released outside Japan. A home version of the game was released in 1980 for the Computer TV Game (コンピューターTVゲーム), the last of Nintendo's home consoles that don't require ROM cartridges, discs or any other removable media.

Gameplay
