Code breaker
There is a hidden code of four colours. Every guess comes back with two numbers and nothing else, and you have ten guesses to turn that into certainty.

How to play
- The code is four pegs long, drawn from six colours, and a colour can appear more than once.
- Each guess is told how many pegs are the right colour in the right place, and how many are the right colour in the wrong place.
- No peg is counted twice: the second number counts only what is left once the exact matches are set aside.
- Ten guesses. Today's code is the same for every player.
- Pick a colour, then tap a slot, or use the number keys one to six.
Questions
Can the code repeat a colour?
Yes, and that is where most people go wrong. Four pegs from six colours with repeats allowed is 1,296 possibilities, not 360.
How is the feedback counted exactly?
Exact matches come out of both the code and your guess first. What is left is compared colour by colour, and the overlap is the second number. That is why four right colours all in the wrong places reads as zero and four, never as eight.
Is it always solvable in ten?
Yes, with the right questions. Five guesses is enough with perfect play, so ten leaves room to think out loud.
