Tetris Party is a deceptively simple, totally addictive puzzle game that is sure to keep you and all of your friends and family entertained for hours on end.

The WiiWare game features 10 never-before-seen single-player and multiplayer variations of Tetris, including Field Climber, Stage Racer, Shadow and Wii Balance Board-enabled modes (Wii Balance Board accessory sold with Wii Fit). Several of the modes give users the chance to take advantage of the unique point-and-shoot capabilities of the Wii Remote controller. The party doesn't stop there, though.

Take the Tetris fun online via Nintendo Wi-Fi Connection, where you can play multiplayer Tetris against up to five friends at a time. You can also see how your Tetris Party skills stack up against the rest of the world using the global ranking system.

Four unique tournaments will be hosted, each made up of one to four rounds. Each round is a variant of Tetris Party that will run bimonthly. At the end of each round, each player will receive a rank and confirmation code from the game.

Tetris Party Tournament No. 3 will feature four rounds – Marathon, Field Climber, Shadow and Stage Racer.

Rounds one and two will feature the Marathon and Field Climber modes. Rounds three and four will require players to compete in the advanced levels. Shadow will be played in Stage 25 and Stage Racer will be played in the most advanced mode, Course T, for the shortest total time to completion.

Players should register here, where they will input their confirmation code. The confirmation code must be entered on the site once for each round the player participates in. Each player's rank will determine the amount of tournament points they receive for that round.

Here’s how the tournament scoring works: If a player ranks No. 1 in a round, he or she will receive 1,000 points, the No. 2 ranked player will receive 999 points, and the player who ranks No. 1,000 will receive 1 point. At the end of the fourth round, Tetris Online will total up all rounds played for each player and rank the top players on a score leaderboard.

The top 500 eligible entrants on the leader board will receive 1200 Wii Points™ from Tetris Online.
