I have the official Tetris already but it's kinda slow and EA doesn't seem like they plan on updating it again ever which sucks because multitasking saved state would be great for it. Are there any good clones out? I can't find any myself.
Master of Blocks: http://itunes.apple.com/us/app/master-of-blocks/id366518170?mt=8 It has a mode where you control what blocks come out and you try to mess up the computer, and it also has a traditional tetris mode.
