Crack the Code: Number Puzzle
Race to crack the secret
Free · Designed for iPad. Not verified for macOS.
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.
PLAY YOUR WAY
- Solo Game — race against yourself, climb the global top-20 leaderboard
- Play with Friends — create a 6-character room code, share it, and race up to 7 friends in real-time multiplayer
LIVE MULTIPLAYER
Watch your opponents' attempt counters tick up live. When someone cracks it first, everyone else gets the news instantly. Decide whether to keep playing for the personal win, or hop out and start a new round.
