Quinn

Quinn is a version of Tetris with some really interesting features, such as playing a tournament over a local network or customizing the appearance of the pieces.

The gameplay is virtually identical to that of the classic Tetris: stack the pieces by forming lines and placing them in a relatively organized fashion to prevent blocking the new pieces as they appear.

With Quinn, there's also a mode where two players compete on the same computer to achieve the highest score. In this tournament mode, you can select from four different types of competition: highest single-game score, highest overall score, maximum playing time, or most lines per minute.

If you consider yourself a good player, you can also share your high score with other players online.
