Take a closer look while playing

Aim for this result
Check the rule below as you play. Deduce a hidden four-colour code within ten guesses, using exact and misplaced feedback. Try the rule on the board, then read the next instruction.
The order of play
- The computer chooses four positions from six colours; repeated colours are allowed.
- Select a code position and then choose a colour. Fill all four positions.
- Check guess records your attempt. Exact means correct colour and position; misplaced means correct colour in another position.
- Each secret peg can match only one guess peg. Use the feedback to narrow the next guess.
- Find all four exact positions to win. After ten unsuccessful guesses the secret code is revealed.
Your inputs
Read the position before choosing your next action. Tap one of four positions, then a labelled colour button. Numbers identify colours as well as the swatches. Press Check guess only when all slots are filled. Try the rule on the board, then read the next instruction.
A useful example
Check the rule below as you play. For secret 1,1,2,2 and guess 1,2,1,3, feedback is one exact and two misplaced. The extra 3 has no match. The game area remains available above the explanation.
One detail worth checking
A careful first move helps you understand the round. Four misplaced matches do not mean four exact positions. Also, repeated colours must not be counted more times than they appear in the secret. Start a new round when you are ready to try again.
