Object of the game
The object is to shoot the floating numbers and
mathematical operands and place them down below
in a balanced mathematical expression such
as 234+14=248. Blank spaces don't matter, so 2
34+1 4=2 48 is acceptable. No operands may be on
the right side of the '=' sign and the result can't be
equal to 0.
The scarabs to the side indicate how many machines
you have left. You may shoot and be shot by the other
player which results in an award of 10 points to the
shooting player and the loss of a piece to the victim.

Running the Game
When the game first starts, it gives you the option to
select the number of players (1 or 2).
Once you have chosen the number of players, the
system gives you the option of choosing the difficulty,
1 through 3 with one being the easiest and three
being the hardest.

Once you have chosen the game difficulty, the game
will commence.
Player 1 plays the game with Paddle 0 and Player 2
plays the game with Paddle 1. If you are using a
Joystick, then it is highly likely, you will only be able to
play a 1 player game.

How To Play Dueling Digits
Press the paddle button to shoot a number, then
move your scarab down below the main screen and
drop your number in one of the slots available.
If you accidently pick up a number or operand you
don't want, then you must position yourself above the
'garbage' hole toward the bottom center of the screen,
then press the paddle button to drop the unwanted
digit. If at any time you accidentally drop a number or
operand in the wrong place so that your expression
shows little chance of balancing, move your scarab as
close to the bottom center of the screen as possible
and press the paddle button. This will release all of
your numbers and allow you to start over.

Scoring:
The four operands used within the Dueling Digits
program are as follows:
+ addition
- subtraction
x multiplication
/ division
Each one of these operands are worth 1,2,3 and 4
points respectively.
The computer goes through the created equation and
adds the value of the operands. It then takes this
total and multiplies it by the length of the smallest
number. That amount is then multiplied by ten, giving
you a total equation score.
You will also receive 10 points for zapping the other
player.
Sound Control:
You can turn the sound on and off within Dueling
Digits by pressing the key
combination at any point.
