Three

If you've ever played the Sega classic Columns (or one of the many knockoffs) you know what to expect from 'Three'. The name refers to the fact that straight pieces comprised of three different colors fall down a Tetris-like playing field. The object is to match up three or more of the same color to clear them from the playing field. The help file is unfortunately not in English, but luckily its not really necessary. It features a two player mode, here's the controls: Player 1 - Arrow keys, Enter to drop. Player 2 - W,A,S,D keys, Spacebar to drop.
