From MG Software:
One of the best and most addictive falling blocks game ever, with 49 unique Ray. traced blocks, Block Drop is very mentally challenging and will test your ability to visualize 2 dimensional space. When things get tough you will need to take your time, so you can easily pause the game to analyze the playing field. As blocks fall, use the arrow keys to move, rotate and flip the blocks. When the blocks form complete rows, the rows are removed and the blocks from above fall to take their place. Use bombs to remove blocks. With enough points you can cancel a troublesome block or do a 'top sweep' to remove the top 4 rows. There are 4 levels of difficulty, the hardest level has 49 unique blocks. To be successful you will need to think ahead. If you turn on 'ciscos cave' you will be shown the 'next block', but you will earn half the points.
