Binary is the simple "on" and "off" language that computers use. Each switch you see in the game represents one of these on/off choices, called a bit. When a switch is on (1), it adds to the total value. When it's off (0), it doesn't.
The switches line up in order, with the one on the left worth the most and the one on the right worth the least. Together, they create numbers that a computer can understand.
For example, if some switches are turned on, their values are added together. That's how a pattern of ons and offs can represent any number.
By flipping the switches in the game, you can see how different patterns create different numbers – and try to match the target number.
