Roll Tetris is a clone of the well
The cilynders falling down are previewed and you can drive them in order to cover
completely an horizontal line that disappears. If you dont, the cylinders will accumulate
one on the other so covering all available space.
Full screen. A Menu will appear moving the mouse to the upper right edge
of the screen.
Below the 'Next' message will appear the next cilynder
to play with.
