Code Breaker

Crack a hidden row of coloured pegs. After every guess you learn how many are right and how many are in the wrong place. Classic 4 pegs or a harder 5 pegs with 8 colours.

How to play

  1. The computer hides a code of 4 coloured pegs (5 on Hard). Colours can repeat.
  2. Build a guess by tapping colours, then press Check. You have 10 tries on Classic and 12 on Hard.
  3. A solid dot means one peg is the right colour in the right place. A hollow dot means a right colour in the wrong place.
  4. Crack the code within your tries to win. Every colour also has its own symbol so you can play without relying on colour.

Tips and strategy

  • Open with two colours in each half, such as red red blue blue, to learn how the colours split.
  • Keep every guess consistent with all earlier clues. Each guess should be a possible answer.
  • Count dots, not positions at first: work out which colours are in the code, then where they go.
  • Hint fills your row with a code that fits every clue so far, so it can speed up a stuck game.

FAQ

Is this Mastermind?
It is the same classic deduction idea, built here with its own look and names.
Can the code repeat a colour?
Yes. Repeats are allowed, which is why the hollow and solid dot counts matter.
How is my best score counted?
As the fewest guesses it took to crack a code, saved separately for Classic and Hard on this device.
