2 PLAYER GAME
OBJECT
To win the most rounds.
• The codebreaker wins a round if they
break the code within 12 guesses.
• The codemaker wins a round if the
codebreaker fails to break the code.
PLAYING
1. Decide who will be the first codemaker.
The codemaker sits behind the codesetting end of Mastermind with the
codebreaker directly opposite.
2. Agree on an even number of rounds to play.
3. At the start of each round the codemaker takes the code-setting unit and
dials in a colour combination. See below. Each of the colours must be
different. Make sure the codebreaker cannot see your secret code!
4. The codebreaker can now begin guessing the code.
To make a guess:
Insert 4 pegs into the holes, starting with the row furthest away from the
codemaker, moving towards the codemaker with each new guess.
If the guess is incorrect:
The codemaker scores the guess (see scoring section, page 4).
The codebreaker continues guessing until the code is broken or they have
used up all 12 guesses. The pegs and scores are left in place throughout
the round.
If the guess is correct:
The codemaker reveals the code and the round is over. Note: When
revealing the code, make sure you don’t turn the code-setting unit around
so that the code sequence appears back to front!
5. At the end of the round make a record of who won, then swap roles.
6. The game ends when the agreed number of even rounds has been played.
The player that wins the most rounds in the winner!

SCORING FOR 2 PLAYER GAME
• For every colour
that matches but
is in the wrong
place, pull out the

notch.
See page 6 for a
scoring example.
3–5 PLAYER GAME
OBJECT
To be the player with the highest score at the end of the game.
PLAYING
1. Play as many rounds as there are players. In each round a different player will
be the codemaker while the others take turns to guess the code.
2. For each round the codemaker sets the code in the usual manner.
3. The player to the left of the codemaker guesses the code first. Turn Mastermind
round to face this player.
4. The codemaker scores the guess (see scoring section, page 5).
If the guess is incorrect:
The next player guesses, using clues from the previous score(s). The pegs and
scores are left in place throughout the round. This will help the codebreakers
with their guesses.
If the guess is correct:
The codemaker reveals the code and the round is over. Start a new round with
the next player being the codemaker.
5. The player with the highest score when all rounds have been played in the
winner!
SCORING FOR 3–5 PLAYER GAME
For every colour that matches but is in the wrong place, the codebreaker
scores 1 point. Pull out the white slider one notch for each match.
For every colour that matches and is in the right place, the codebreaker
scores 2 points. Pull out the red slider one notch for each match.
For guessing the correct colour combination (all matching colours in the
right places), the codebreaker scores 10 points. Refer to the box side panels
for more examples on how to score the codebreaker’s guesses.
Mark the codebreaker’s score on the scorecard as explained on page 7.
THE CODEMAKER’S SCORE
The codemaker’s score won’t be added up until the end of the round. For the
group game, the codemaker’s score is as follows:
3 PLAYER GAME
If the codebreakers
don’t guess the code,
the codemaker scores
40 points.
4 PLAYER GAME
If the codebreakers
don’t guess the code,
the codemaker scores
30 points.
5 PLAYER GAME
If the codebreakers
don’t guess the code,
the codemaker scores
25 points.

ADVANCED PLAY
In this advanced game, the codemaker is allowed to use two or more of the
same colour in the code. Agree before starting to play if this is allowed – but
don’t tell the codebreakers if you are using duplicate colours!
STORAGE
To store the game, put all the pegs in the tray and replace the peg cover.
Disassemble Mastermind to store it in the box.
TIPS
SCORING EXAMPLE
The secret code in this
example is pink – red –
blue – yellow.
The codebreaker’s
guess has two
matching colours in
the wrong places and
one matching colour
in the right place.
The codemaker pulls
out the white slider
2 notches and the
red slider 1 notch.
In a game with 3
or more players,
this would
score 4 points.
MAKING A GOOD GUESS
At the start of the game there won’t be many clues to base your
guesses on. As the game progresses, you will see a pattern of colours
and scores forming. Look carefully which lines scored well and compare
these with other high-scoring lines when making your guess. Lines that
have no score are also useful, as you know that none of these colours
are in the secret code.
