Place the batteries into the clips, and turn it on to check that they are in

up.
How to Play the Game
First, turn on your Binary Blaster. The power slide switch is located on the
top left side of the PCB. Slide it to the "ON" position - to the left.
You may also want to check the sound switch. You can slide this to either
the left or right, depending on if you would like to play with sound or not.
If nothing happens, it may be that your batteries are placed incorrectly.
Please make sure to double check the polarity.
When you first power up your Binary Blaster, you should notice that the
buttons light up quickly from right to left, and then the display begins

To begin a new game, simply press one of the buttons.
