Pick four colours and submit your guess.

Guess
How to play

The computer has picked a secret code of four pegs from six colours. You have ten guesses to crack it.

  • Tap a slot in the current row, then tap a colour. Or tap a colour, then a slot — either works.
  • Hit Submit guess once all four slots are filled.
  • After each guess you'll see feedback pegs to the right of the row:
    • Dark peg — one of your pegs is the right colour in the right position.
    • Light peg — right colour, wrong position.
    • Feedback pegs aren't shown in any particular order — that's the classic rule.
  • Classic allows duplicate colours in the code. Easy guarantees four different colours.
