Alexander Randolph (4 May 1922 – 28 April 2004) was an American designer of board games and writer. Randolph's game creations include TwixT, Breakthru, Inkognito (with Leo Colovini), Raj, Ricochet Robot, and Enchanted Forest (with Michael Matschoss).
Randolph was a son of self-described "rich parents" who attended private school in Switzerland. He spent his early years in various occupations, including military intelligence and as an advertising copy editor in Boston.
In 1961, Randolph moved to Japan and became a professional game developer, performing initial work on TwixT. During this time, he became a dan player in shogi.
In 1962, Randolph (along with Sid Sackson) was commissioned to start a new game division for Minnesota Mining and Manufacturing (also known as 3M). Through 3M, Randolph created and published such games as Breakthru, Evade, Oh-Wah-Ree, and TwixT.
Randolph moved to Venice, Italy in 1968, continuing his career as a game developer with the company Venice Connection established with Dario De Toffoli and Leo Colovini.
Randolph died aged 82 in Venice on 28 April 2004.
In 2016, as a testimony to his great career, Fabulous Games published ADDX - the first ever digital game from Alex Randolph: https://apps.facebook.com/addx-game/
