Hello, My question is simple -- which tetris implementation is fastest on a PC platform? It will be perfect if there exist any with freely adjustable speed, independent of levels. I've seen many tetrises but all of them were not challenging (by measure of speed) even on the highest levels after some years of tetris experience. My favorite Tetris is the one which comes with DOS Navigator -- the good old MS-DOS shell. To be precise, currently I'm using NDN -- DN port for win32. Although its speed on a level 10 is not sufficient for me too, I solved this problem by patching NDN executable and reducing delay between the figures moves. But there is some inconvenience -- I need actually two speeds. First is "regular fast" and other is "challenging fast". The last is used for training, the first is used for general play. So every time I need to switch speeds, I have to repatch delay. One of the planned solutions is to assign these speeds to a several levels in the game with patch to disable level ups after reaching number of lines. But I think the problem can be solved in more elegant way -- by changing my NDN tetris to some another. So I've downloaded some tetrises -- only to find that all of them being simply a crap but with some kewl graphics and effects (especially compared to NDN's 80x25-console tetris) and with stupid sounds... ;( Sorry for bad English, my native language wildly differs from it and I have very little experience in the conversation with english-speaking people.
Try Heboris + Unofficial expansion or Lockjaw with Death mode settings. Speed is comparable with this famous Tetris the Grand Master video. (additionnal reading/information for this Tetris variant). By the way, welcome ! Don't worry for your english, you're not the only one whose native language isn't english .
