A classic deduction game
The computer hides a secret code of 4 colours (or 5 for a harder game). Pick colours for your guess and press Check. You get a clue for each guess: a black dot for every colour in the right place and a white dot for every right colour in the wrong place. The clues don’t tell you which colours are right – that’s what you work out.
Crack the code within 10 guesses. Choose 6 or 8 colours and whether colours can repeat in the code. It’s a great way to practise logical thinking – for kids from about eight and for adults who like puzzles.
How to use
- Tap colours to fill your guess; ⌫ removes the last one.
- Press Check.
- Read the clue: black = right colour and place, white = right colour, wrong place.
- Use the clues to crack the code within 10 guesses.
Ideas for using it
- Start. first guess two colours twice, e.g. red-red-blue-blue.
- No dots?. none of those colours is in the code – rule them out.
- Easier. 4 pegs, 6 colours, no repeats.
- Harder. 5 pegs, 8 colours, repeats allowed.
