This game doesn't have a real name. Vertical drop down tic tac toe, minimax (as in the title bar) is a bit of a nightmare logistically, so I decided to list it as Upuzz, the name used in the source code.
Vertical drop down tic tac toe, minimax
This may have been the basis of SoftwareEdition Vier Gewinnt, at least it looks very similar.
