About Colour Code

Every guess buys information, so the wasteful opening is the real mistake. The pegboard is readable at a glance, which keeps the game about logic rather than squinting.

How to play Colour Code

Deduce the hidden four-peg colour code.

Controls

· Tap the colour buttons to fill the row.
· Tap CHECK to submit your guess.

Rules & scoring

· A black marker means the right colour in the right place, white means right colour wrong place.
· Crack it in fewer rows for a better score.

Tips

· Start with two colours only — it narrows the field fast.

Retro inspiration
