What is the Mastermind?
The computer hides a code of coloured pegs. Build a guess and submit it: a ● black clue means a correct colour in the correct position, a ○ white clue means a correct colour in the wrong position. Use logic to crack the code in 10 guesses or fewer. Increase difficulty with 5 pegs, 8 colours or allowed duplicates.
How to use the Mastermind
- Tap colours to fill the guess row.
- Tap Check to see the clues.
- Deduce the code before you run out of rows.
Tip
Start with guesses that test several colours at once, then use the clues to rule colours in or out.
This Mastermind is 100% free, needs no signup and runs privately in your browser – on phone, tablet or computer.
