Think of it from a random guess perspective. Guessing a number randomly generated between 0-16 is easier than guessing one between 0-8.
Now think that all passwords are stored in certain amount of bits, so let’s compare 4 and 8 bits.
Each bit has a chance to be either 0 or 1, so guessing a single bit’s possibility is 1/2.
Guessing the correct orientation of 4 different bits takes 1/24 = 1/16
Guessing the correct orientation of 8 different bits takes 1/28 = 1/256
Now think passwords being stored in more bits(=longer password)
What I’m supposed to do in the game is not really obvious, so didn’t really understand what to do there.
