Crack the Code: Number Puzzle

Crack the Code is a fast, satisfying logic puzzle that tests your deduction skills against yourself or up to 7 friends in real time.

The rules are simple: the app picks a 4-digit secret code with no repeated digits. Your job is to crack it. After every guess, your digits light up with color-coded clues:

- GREEN — right digit, right position
- ORANGE — the digit is in the code, but in the wrong spot
- GRAY — not in the code at all

Use the colors to narrow it down. Whoever cracks the code in the fewest tries — and the shortest time — earns the high score.
