STetris is the exact counterpart of P. C. M. van der Arend's Columns. It uses the same screen layout, the same graphics, the same scrolling text that looks as if it came out of a dot-matrix printer, only the blocks are, naturally, smaller. It is a solid, classic Tetris clone, it was the first one for the hi-res monochrome monitor and from those I know (there were at least three or four more) has remained the best.
