Code Breaker variants
Other ways to play Code Breaker, each one ready to play here. Read how a variant changes the rules, then start a game with it chosen in the table setup.
Bulls and Cows
The pencil-and-paper ancestor of the peg game: the secret is a number of different digits, and each guess earns bulls for digits in place and cows for the rest.
Word code
The secret is a real word: every guess must be a word too, and each letter of a guess is marked as in the right place, elsewhere in the word or not in it.
Five pegs, eight colours
The larger board: codes of five pegs from eight colours, 32,768 of them, with twelve guesses to find the right one.
Three pegs
A shorter code for a quicker game: three pegs from six colours, 216 possible codes, with the standard ten guesses.
No duplicates
The codemaker's code must use four different colours, which leaves 360 possible codes; the codebreaker's guesses may still repeat colours.
Blanks
An empty hole counts as one more colour: the code and the guesses may leave holes empty, and a blank in the right place scores like any other colour.
