Quadra for Windows is a Tetris clone with multiplayer features. The sheer number of clones evidences the success of Tetris, but if you think that you've seen every variation of Tetris out there, you haven't played Quadra. It works on the same premise as the original game, but this rendition of the block-dropping favorite incorporates so many innovative features that it feels like an entirely new game. Quadra is an addictive puzzle game and competitive, action-packed, multiplayer game all in one. It offers incredibly smooth game play, block shadows to help you drop blocks with precision, and recursive line clearing allowing blocks to combine in violent chain reactions that will send your opponents crying back to their mommy! There are ten levels with colorful background images and matching sound effects with an integrated CD music player. You can also post your best performances on a worldwide high score table.
