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, you see two clues:

• how many of your digits exist anywhere in the secret
• how many are in the correct position

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