How to play Code Breaker

A secret code of coloured pegs is hidden. Find it in at most 10 guesses. After every guess you get feedback pegs:

  • Black peg — a peg of the right colour in the right position.
  • White peg — a right colour in the wrong position.

The feedback pegs are not in any particular order. Duplicates are counted fairly: if the code has one red and you guess two reds, you get credit for only one of them.

Controls

  • Tap a colour in the palette to fill the next hole; tap a hole to empty it (or to choose which hole the next colour goes into).
  • Keyboard: 1–8 pick colours, Backspace removes, Enter submits the guess.

Options

Play the classic 4 pegs / 6 colours or the harder 5 pegs / 8 colours, with or without duplicate colours in the code. In Computer guesses mode you make a secret code and the computer cracks it, using Knuth's minimax strategy (at most 5 guesses for the classic game) — it shows how many codes are still possible after each guess.

Your fewest-guesses record is saved for every setting.
