What you need to achieve

How a round unfolds
- 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.
Input guidance
Keep the goal in view while choosing a move. 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. Keep the goal in mind before your next move.
An example before you play
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. Keep the goal in mind before your next move.
Avoid this misunderstanding
Take a moment to check the current turn. Four misplaced matches do not mean four exact positions. Also, repeated colours must not be counted more times than they appear in the secret. Try the rule on the board, then read the next instruction.
