What Was the First Video Game Ever Made? The Top Contenders Explained

There's no single "first video game"—the concept evolved through experiments and prototypes. But these three are the strongest contenders, each pioneering a different pillar of the medium.

Top Candidates

OXO / Noughts and Crosses (1952)

Alexander S. Douglas, EDSAC computer (Cambridge University). Tic-tac-toe displayed on a cathode ray tube. First digital graphical game—proved a computer could render interactive visuals.

Tennis for Two (1958)

William Higinbotham, Brookhaven National Laboratory. Oscilloscope display, analog computer. Two-player tennis simulation with gravity physics. First interactive entertainment game—built purely for fun, not research.

Spacewar! (1962)

Steve Russell et al., MIT PDP-1. Two spaceships, gravity star, torpedoes, hyperspace. First digital computer game designed for play (not demo). Inspired Nolan Bushnell → Atari → arcade industry.

Why No Definitive Answer Exists

• Definitions vary: "video" (raster display), "game" (rules, win/lose), "computer" (digital vs. analog).
• Early projects were lab demos, not commercial products.
• Documentation lost; many were one-off experiments on unique hardware.

Each pioneered a pillar: OXO (digital graphics), Tennis for Two (interactive fun), Spacewar! (code-based gameplay, community, mods).
