i played this religiously back in the day. it's called lines and boxes where i am from, in high school. whenever class was boring (which was often), me and my then best friend would play this game on the sheet where we were supposed to be taking notes. i probably still have a couple of games from '89.

the variation is dots in a pyramid shape, and then to make triangles out of them.
