Question 1

How do you play Mastermind?

Accepted Answer

The computer secretly picks a sequence of colored pegs. On each turn you place a row of colored pegs as your guess and press Check. You get black pegs for each correct color in the correct position, and white pegs for a correct color in the wrong position. Crack the full code within the turn limit to win.

Question 2

What do the black and white feedback pegs mean?

Accepted Answer

A black peg means one of your guessed pegs is the right color AND in the right position. A white peg means a peg is the right color but in the wrong position. The feedback never tells you which specific peg is correct, only how many — that is the puzzle.

Question 3

How many guesses do I get?

Accepted Answer

You get 10 guesses for a 4-peg code, 12 for a 5-peg code, and 14 for a 6-peg code. Each guess gives you feedback to logically deduce the secret before you run out of turns.

Question 4

Can colors repeat in the secret code?

Accepted Answer

By default colors do not repeat, which makes the puzzle friendlier for beginners. You can toggle Allow duplicate colors in the difficulty settings for a much harder classic Mastermind challenge.
