Computers of the 1950s were very different than modern computers. They took up so much space that it often required several rooms. They also had huge power requirements and generated large amounts of heat. Computers of the 1950s were also highly unreliable, often requiring many hours of troubleshooting and programming to accomplish a few minutes of productive work. Also, computers of that era were not useful for much more than mathematical calculations, there being no internet to surf or games to play, most homes had no need or use for a computer.

No sir/ma'am they did not have games on the computers. Back then they would use computers for research and military use not much of a use for video games. if you have any more questions feel free to ask me.
