How to play
- Find the hidden colour code. Tap colours or press keys 1–8; Backspace undoes, Enter submits.
- ● = right colour in the right spot. ○ = right colour, wrong spot.
- Easy: 4 pegs, no repeats, 12 guesses and a live count of codes that still fit your clues. Hard: classic 4 pegs with repeats. Extreme: 5 pegs, 7 colours. Nightmare: 5 pegs, 8 colours, only 8 guesses.
