Tetris DS is the newest iteration of the classic puzzle game, this time with six modes take advantage of the DS' abilities (including online play). In addition, each mode has a different theme based on a classic Nintendo game, such as the classic Tetris mode which features Mario running and hopping on enemies as you play.

Four of the modes have yet to be revealed (Nintendo claims the info on them will be "released periodically"), but the newest mode unveiled is called Touch.

The second mode, called "Touch," utilizes the DS's touch screen for a unique form of play. You'll be able to drag the Tetriminos where you want them using the stylus and spin them by tapping them. Unlike regular Tetris, Touch isn't realtime, which means you can take all the time you need to plan your moves. It's not clear whether the screens below are taken from the Touch mode; it seems unlikely, though, as it would be impossible to drag the blocks onto the top screen.

The "screens below" refers to several new shots of a mode featuring a Balloon Fight theme, one of which seen here on the right. More screens available at the link, though one screen sorta says it all with Tetris.

Tetris DS is scheduled for March 20.
