Secret Code Cracking vs Mastermind

CRACK THE CODE. SAVE THE AGENT. Secret Code is the classic code-breaking game, also known as Bulls and Cows, with a spy story on top. Guess the hidden code, read the clues and crack it before the trap closes. HOW IT WORKS Make a guess. A green peg means a right digit in the right spot, and a half peg means a right digit in the wrong spot. Use the clues to narrow it down and crack the code in as few guesses as you can. PICK YOUR AGENT Play as Nikita, Biscuit the corgi or Jack, and make them yours with skin tone, hair, eye and outfit colors. SIX SPY GAMES • Wire Cut: find the right row of colored wires • Pattern Lock: swipe the secret unlock pattern • Vault Glyphs: match the shapes and colors • Tone Lock: crack a short tune by ear • Safe Dial: spin the combination and feel every click • Codeword: guess the 4-letter password OPERATIONS Five operations with six missions each. Every mission is a different game in its own trap room: rising water, laser grids, crushing walls, a bomb fuse and a spiked ceiling. Every right digit slows the trap down. Each operation ends with a finale that chains two or three locks. DUEL Two players, one code. Race a friend live over Game Center, or take on the AI at Rookie, Pro or Legend. Fewer guesses wins. DAILY AND WEEKLY A new daily code every day, the same for every agent, and a different spy game every week. Keep your streak going and compare scores on the leaderboards. ALSO • Classic Code in 3 or 4 digits with unlimited guesses • Hints in every game • Achievements and Game Center leaderboards • 15 themes to unlock with stars • Theme music and sound effects for every game • Detailed statistics A workout for logic, deduction and memory, in short sessions or long ones.

The classic code-breaking game — reimagined. Mastermind: Code Break challenges your logic and deduction. Each game, a secret 4-color code is generated. You have 10 attempts to crack it. After every guess, hint pins guide your thinking — black for the right color in the right spot, white for the right color in the wrong spot. No luck. No timers on screen. Just pure deduction. TWO DIFFICULTY MODES Normal mode allows color repetition — the same color can appear more than once in the secret code, which dramatically increases the challenge. Easy mode guarantees each color appears at most once, perfect for new players or a quick game. TRACK YOUR PROGRESS Every game is recorded. Head to your stats screen to see your win rate, current and best win streak, your fastest solve time, your average number of guesses, and a full guess distribution chart — just like Wordle, but for colors. BUILT FOR DAILY PLAY Each game takes 2–5 minutes. The clean, distraction-free interface keeps you focused on the puzzle. No sign-in required. No internet connection needed. Your stats and settings are saved automatically between sessions. FEATURES AT A GLANCE • 6 colors, 4 positions, 10 guesses • Easy mode (no repeated colors) and Normal mode • Per-guess elapsed time display (can be hidden in Settings) • Win rate, streaks, best time, average guesses, guess distribution • Separate stats for Easy and Normal modes • Settings saved between sessions • 100% offline — no account needed • Accessible dark UI with high-contrast colors Download free and start cracking.
