Crack The Password

A numeric lock. A few wrong guesses. Each one comes with a note: how many of its digits are in the code, and whether they sit in the right box. Read the clues together and only one code survives.

Crack the Password turns the classic lock riddle into a full puzzle game, from gentle 2-digit locks to 5-digit expert codes.

83 HAND-CHECKED LEVELS
Eight packs that introduce one idea at a time: longer codes, mixed clues, repeated digits, fewer attempts. Every puzzle has exactly one solution and was graded by a solver that only uses the deductions a person would make, so the difficulty curve is honest.

REASON LIKE A DETECTIVE
• Sudoku-style notes: each box shows the digits that can still go there.
• A digit strip crosses a digit out everywhere or circles it as confirmed.
• Long-press a clue to apply it in one move: cross out its digits, or clear them from the boxes it shows.
• Full undo and redo, so trying an idea costs nothing.

EVERY GUESS TEACHES YOU SOMETHING
A wrong code costs an attempt, but it joins the board as a new clue with its real feedback. Solve on the first try for three stars.

STUCK? TWO KINDS OF HINT
Let the built-in solver prune your notes, or reveal one digit. Each hint costs a star, so use them wisely.

LEARN BY SOLVING
The tutorial does not explain the controls; it solves the first lock with you, one deduction at a time.

If you have ever stared at that lock puzzle and wished it went on, this is the game for you.
