The concept is based around binary mathematics; Where you have a series of 1’s and 0’s to represent larger numbers. In binary, the number furthest to the right represents 1, then 2, then 4, then 8, and so on– doubling each time. If the binary number has a 1, you add the value of that place to the number, and if it’s a 0, you skip it. This is what makes computers work. In the game, you have eight places (which run from 1 to 128) that you can switch on and off. You’re given a number between 1 and 255 (as high as eight places can calculate), and then you’re timed on how long it takes you to flip the switches on or off to get the right binary number.
