Polytris is a variation of Tetris, the stand-up arcade game. It plays
just like the video game, but with a few new twists.
Simply put, you must drop falling shapes into a box as neatly as
possible. If you fill a horizontal line completely (that is, if there are no
empty spaces in the line) the line will disappear.
Each line you destroy in this way brings you closer to your "goal",
displayed in the bottom right-hand corner of the screen. If you fill the box
to the top with a hole in each line, the game ends.
In the arcade game, Tetris, you will be served a variety of shapes,
all made from four squares. There are in fact seven different shapes possible
from four basic blocks:
## ### #### ### ### ## ##
## # # # ## ##
In Polytris, you may choose from shapes made from three, four or five
blocks. This gives you two, seven, or eighteen shapes respectively. The
three-block game is simple, if fast, and better suited to children. The five-
block game is more like a jigsaw puzzle and less like a video game.
When you begin the game ("RUN POLYTRIS") you'll be asked whether or not
you want to see the next block. This helps you plan where to dump a piece,
since you know what's coming next. Then, you'll choose sound, starting level
and number of blocks in a shape.
Use your joystick (or Paddle 0 if you still own paddles) to move the
blocks left and right. Press button 0 to rotate the block 90 degrees counter-
clockwise to try and fit it in.
When the game is over, you may Quit, Play again, or Continue where you
left off.
Polytris uses measly 'ol low-res graphics. It should run on everything
from an old Apple ][+ up. It was written in AppleSoft BASIC and compiled
under DOS 3.3, and the compiled version is incompatible with ProDOS -- but
POLYTRIS.SRC, the BASIC code, is included. If you have a faster compiler,
you may need to change the pause length (PZ = ## in lines 1000 to 1999) to
accomodate the change in speed.
Questions? Comments? If they're nice, I can be reached at
MLARKEN@AC.DAL.CA. If they're not nice, the address is wrong.
I wrote Polytris to see if I could. It's public domain, so you may not
sell it, and may distribute it freely if this documentation is included. You
may modify the source code as you wish, provided you leave in all remark
statements.
