Crack The Code

Crack The Code is two code-breaking games in one app — pick your game from the switch at the top.

Lock clues — the deduction game
A secret code of distinct digits is locked away. Every clue row shows a guess the lock has already seen, plus exactly what that guess tells you — how many of its digits are in the code, and whether any sit in the right spot. Combine the clues, set the lock dials with + / −, and hit Unlock.

- Codes of 3, 4, or 5 digits
- Score, Lock level, and Best streak tracking — fewer attempts earn more points
- Free play, Timer mode (crack it before the clock hits zero for a time bonus), and Daily lock (one puzzle per day, the same for everyone, with its own streak)
- Help reveals one true digit (−30 pts); Hint states a fact that must be true (−10 pts)
- Tap any clue row for a plain-language explanation of what it means

Keypad guess — the classic guessing game
A Mastermind-style game against a secret digit code. Enter guesses on the keypad (or a keyboard) and get pegs for every guess — green for a digit exact and in place, amber for a digit in the code but misplaced. Ruled-out digits fade on the keypad so you never waste a try.

- 4 digits / 10 tries, or 5 digits / 12 tries
- Attempt pips counting down, win/loss reveal, play again instantly
