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.

Verdict
The clearest difference is in-app purchases: Crack the Code at none against Fill's 1. Crack the Code also leads on ads (none vs shown). Fill's advantage is update cadence (every 6 days vs every 2 weeks) and iOS requirement (12.0 vs 15.1). On price, rating, review sentiment and ratings volume there is nothing between them.
