I know Mastermind very well, so I understand the premise of the puzzle. What I don’t understand is how multiple different letters can all be in the first spot. O, N, and E are all in the first letter spot according to the puzzle. That’s what I’m not understanding.
I also wondered the same thing… the dot means it is in the correct spot not necessarily the spot that is marked in order. For example:
on the next page there are four mirrors. The second mirror is indicating there are three of those exact same letters in the answer. This mirror tell us: Correct, incorrect, incorrect, and then one letter not in the answer. The N is correct but not in the right spot.
