The original version of Tetris was created by Alexey Pajitnov for the Elektronika-60 computer. It was never released commercially. It was also playable on the successor DVK-1 and DVK-2 computers, although it is unknown whether that is a different version, or simply the same code running on a different computer. Minor visual differences are present, but the gameplay is the exact same.
One of the very first erotic video games ever released. Gameplay is comprised of a strip variation of rock-paper-scissors, based on a concept popularized by "Konto 55-gou no urabangumi wo buttobase!", a variety show which ran from April 27, 1969 to March 29, 1970. Players set how many articles of clothing they would like their opponent Megumi to wear, and after each victory she removes one piece until she is nude.

The Sumerian Game is a text-based strategy video game of land and resource management. It was developed as part of a joint research project between the Board of Cooperative Educational Services of Westchester County, New York and IBM in 1964–1966 for investigation of the use of computer-based simulations in schools. It was designed by Mabel Addis, then a fourth-grade teacher, and programmed by William McKay for the IBM 7090 time-shared mainframe computer.
The Sumerian Game has been described as the first video game with a narrative, as well as the first edutainment game. As a result, Mabel Addis has been called the first female video game designer and the first writer for a video game.
A game of pool (billiards) developed by William George Brown and Ted Lewis in 1954 on the MIDSAC computer, intended primarily to showcase the computing power of the MIDSAC.
"The game displayed a 2-inch rendition of the pool cue for the players to line up their shots and ran a simulation of the colliding and ricocheting balls in real-time, implementing a full game of a cue ball and 15 frame balls for two players. Graphics were drawn in real-time on a monochrome 13" point plotting X-Y display, the screen being updated by the program 40 times a second (that is, in a normal in-game situations with 2 to 4 balls moving at once). However, for time constraints, the table and its pockets weren’t drawn by the computer graphics, but were rather drawn manually onto the display using a grease pencil."

A game of draughts (a.k.a. checkers) written for the Ferranti Mark 1 computer by Christopher Strachey at the University of Manchester between 1951 and 1952. In the summer of 1952, the program was able to "play a complete game of Draughts at a reasonable speed".
