CHROMA CODE

A secret sequence of colours is hidden from you.
Each colour appears at most once. Make a guess, read the
feedback, and use logic to crack it. No timer. Pure deduction.

How to Play

1. Select colours from the palette to fill every slot, then submit your guess.
2. ● means right colour in the right spot. ○ means right colour, wrong spot.
3. Use the feedback to narrow down the secret sequence. Each colour appears at most once.

Expert Tips
Test systematically: On your first guess, use colours you haven't tried before to maximise information gained.
Track eliminations: Colours with no ● or ○ feedback are definitely not in the sequence — rule them out immediately.

Chroma Code

Goal

A secret sequence of colours is hidden from you. Each colour appears at most once. Make guesses, read the feedback, and use pure logic to crack the code.

Feedback

● Filled circle — correct colour in the correct position.
○ Empty circle — correct colour but in the wrong position.
No dot — this colour does not appear in the sequence at all.

Scoring

Each level starts at 500 points. You lose 60 pts for every guess beyond the first. Fewer guesses = higher score. Levels grow longer and harder as you progress.

Tips

  • Your first guess is essentially free — use it to test as many new colours as possible.
  • A colour with no feedback (no dot) is eliminated — never use it again.
  • If you get ○, try that colour in every other position until you find its home.
Why this sharpens your mind

Deductive Reasoning

Each guess is a hypothesis. Reading the feedback and updating your mental model is the same logical process used in scientific thinking and debugging.

Working Memory

Tracking what you know, what you've eliminated, and what remains requires holding multiple constraints in mind simultaneously — a direct workout for working memory.
