Mastermind

Crack the hidden 4-colour code within 8 guesses.

How to play

Set a row of four colours and submit it as a guess.
Feedback pegs tell you how close you are: one mark for each colour in the right position, a different mark for each right colour in the wrong position.
The pegs don't say which peg is which — deduce it from guess to guess.
Nail all four positions before you run out of rows.

Controls

Pick colours for each slot · submit the row

How you earn

Cracking the code earns the bigger bonus.

Tip

Spend your first couple of guesses testing which colours are even present before worrying about order.
