The goal of this another Tetris-clone is to clear as many lines as possible, and do not allow blocks stack up to the top. New feature is a 'NOT' activated by player during the game. When four lines are cleared simultaneously the player receives a 'NOT'. For each 'NOT', a notch is cut out of the border on each side, starting from the bottom. There are 9 levels of difficulty accompanied by different background pictures. This is a shareware version, which is identical to the registered version except for the 'nag screen' at the end.
