Where it came from
Mastermind was created in 1970 by Israeli telecommunications expert and antique dealer Mordecai Meirowitz. He drew inspiration from the classic pencil-and-paper game Bulls and Cows, which had been popular for decades. Seeking to modernize the deductive logic challenge, Meirowitz developed the physical board and colorful pegs that characterize the game today, aiming for a streamlined experience that emphasized strategy over luck.
After struggling to find a publisher, Meirowitz finally showcased the game at the Nuremberg International Toy Fair in 1971. Its reception was immediate, as buyers were impressed by its tactile simplicity and the depth of its mathematical structure. Invicta Plastics eventually acquired the rights to mass-produce the game, and it became a global commercial success, eventually being licensed to major companies like Hasbro for wider international distribution.
