Crack the hidden colour code. Each guess is scored: how many pegs are right in colour and place, and how many are the right colour in the wrong place.

Tap a colour from the palette to fill the current row (tap a filled peg to clear it), then hit ✓ CHECK — the button sits right on the row you are filling in. Feedback: ● black = right colour & place, ○ white = right colour, wrong place. Repeats are allowed. Tap colours to fill the row, then ✓ CHECK on that row. ● black = right spot · ○ white = wrong spot.
