Step by step
- 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.

How your actions work
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. Start a new round when you are ready to try again.
Follow the example
Begin with the basic rule, then follow the result of your action. 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.
An important reminder
Four misplaced matches do not mean four exact positions. Also, repeated colours must not be counted more times than they appear in the secret. Keep the goal in mind before your next move.
