Numble vs Crack the Code

Crack the code. Every day. Numble is a daily code-cracking puzzle. One vault. Four digits, no repeats. Seven guesses to break in. Here's the twist: every guess returns counts — not positions. Greens — how many digits are right AND in the right spot Yellows — right digit, wrong spot You're never told WHICH slot. Pure deduction. No luck. A NEW VAULT EVERY DAY A fresh code drops at midnight — the same one for everyone. Solve it, then compare with friends. KEEP YOUR STREAK ALIVE Show up daily and your streak climbs. Miss two days and it resets — but you get one repair every 30 days. How long can you hold the line? CLIMB THE VAULT LADDER Work through a 20-chapter story arc, then go endless. Vaults evolve from gunmetal steel to gold to alien obsidian. The deeper you go, the rarer the prize — and the bigger the flex. DUEL IN REAL TIME Challenge a friend head-to-head. Set a code, race the turn clock, crack theirs first. Pure skill — no hints, no power-ups.

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.
