Tetris DX

As in Tetris , DX is a puzzle video game in which players must fit a vertically descending series of blocks to form complete rows, making the blocks disappear; with the game ending if the blocks fill the screen beyond the top row of the play space. DX introduces additional gameplay modes. The core gameplay mode, 'Marathon Mode', is the closest to the original game , with blocks falling at a faster speed for every line cleared by the player. Additional gameplay modes include 'Ultra Mode', requiring players to clear as many lines within a two-minute time limit , and '40 Lines', where players can set the starting level and height, and must clear 40 lines as quickly as possible.

The game also supports competitive play in 'Vs Mode', where players can play against computer opponents on easy, normal or hard difficulty, or another player with a copy of the game by using the Game Link Cable . DX also allows up to four players to save their game data, including names and high scores. Each saved user is given a Power Rating, representing their performance across the game modes.
