As I mentioned, the main selling point of the Microsoft Entertainment Pack was a Windows version of Tetris, which was a wildly popular in the mid to late 1980s after being created by Alexey Pajitnov in the Soviet Union.
Throughout the game, random pieces fall from the top of the playing area. Using the arrow keys you rotate and move the pieces in order to form a solid row of blocks across the playing area. When you do, that row vanishes.
Tetris could be played by one or two players.
