- A black peg means a right colour in the right place. A white peg means a right colour in the wrong place.
- The clue pegs don't tell you which slot they're about, only how many.
- Start with two colours, like red red yellow yellow, to learn a lot at once.
- Switch off repeats for an easier code with four different colours.
