Tetris DSDS

The long blue bar. The yellow block. And those darn zigzag things whose images stay on your brain.

These familiar Tetris shapes started a generation of video game fans. Now Nintendo is putting a new spin on the classic with Tetris DS, available March 20 exclusively for Nintendo DS, which incorporates the use of Nintendo Wi-Fi Connection, Nintendo's wireless gaming service.

Hard-core and casual gamers alike became obsessed with the original. Tetris DS builds on that emotional attachment by combining the original game with new types of game play that could only be possible on Nintendo DS.

Each of the six modes of play features a theme based on a classic Nintendo game, such as Super Mario Bros., The Legend of Zelda or Metroid. The traditional Tetriminos (falling blocks) and line-clearing strategy remain the staples of the game, but the touch screen adds a new element of interactivity.

Some modes give players special Tetris puzzles to solve. Others feature head-to-head action between two players, or massive wireless battles between 10 DS users, even if only one player has a game card. Players also can log onto Nintendo Wi-Fi Connection to compete in two- or four-player battles. Tetris DS even includes a point-based rating system based on players' battle results. Opponents can see one another's ratings, which indicate their skill levels.

Every gamer, whether competitive or casual, will find a way to reconnect with one of the most popular puzzle games in history.
