_________________________
4-Tris is a fabulous game. The gameplay is reminiscent of Tetris (that should be obvious from the name ;-) so if you like Tetris, you should like this game. All of the mind-numbing addictiveness is there, and the graphics are all they need to be. A nice touch is the use of special new fonts for the score and other status information. And the soundtrack is superb! For those of you who tire of it eventually, you can disable the music at any point in the game.

Other handy features include a 'Next Piece' preview and a sound test screen accessible from the startup screen. If you watch closely, you'll notice a nice touch on the title screen - the copyright date scrolls from 1979 to 2000. I'll leave it as an exercise to the reader to decide why these dates are relevant. I can say that you will find yourself spending waaaay too much time playing this game
