For a all well known game Tetris. It's full functional. It Common game Tetris. It's a full for play. It's effective in all functions do not hesitate to try it. In this case the main interest it's not all about the game but the algotithmus used in it. Though it has been programmed in text mode it's non the less nontheless not less interesting for it. I suppose someone is going to make the graphics part of it - do it if you like. Later it came to me that the programme can by made by reducing it to the necessary minimum, this was the fast that contributed to creating the Tetrisl.pas source, light version of Tetris.
