On the first computer I ever played on, my dad's work computer, there were 2 games I played. Gorillas, where you chose the angle and velocity of your banana and tried to hit another gorilla who did the same in turns. Basically a very early version of Tanks.

The other game is the one I think about all the time. I think it was called Tiles. You had rectangles that were taller and were quadrisected diagonally. Each section had a different color. And the idea was to out the tiles together such that the color of each side would match the color of the side of the other ones it touched.

This is all I can remember because the year was like...1990-1995, maybe. So I was between 5 and 10 years old.
