EA has released an iPhone and iPod touch edition of Tetris through the App Store. The company also announced Scrabble and Sudoku, but those are expected to launch later in the day and weren't active as this post was published. All games had previously been published for the iPod, but several gameplay updates take advantage of the iPhone's input abilities.

Tetris is yet another copy of the falling-piece puzzler, where you complete rows to clear them away. In addition to the classic game mode with its original rules, this new version includes a "Magic" mode, with many embellishments. Shaking the iPhone, poking, and flicking blocks allows new ways to solve boards; you can even shrink blocks through a pinch or draw your own shapes. Tetris costs $14.99.

Scrabble follows its iPod sibling, with few game changes in the update. You'll spell words with letter tiles, earning more points for longer and more elaborate moves. You can play alone against the iPhone, or up to four players can compete by passing the device around. Scrabble costs $14.99.

Sudoku includes 10,000 of those number-grid puzzles in this iPhone version. Several difficulty modes, tutorials, and hints can help players of any ability. Sudoku costs $9.99
