About PIN Cracker
PIN Cracker is a deduction puzzle in the Mastermind tradition: there's a hidden numeric code, and each guess returns feedback about how many digits are correct and how many are in the right position.
Every guess is information. Played well, a code that looks impossible narrows to a single answer in a handful of attempts — the skill is in choosing guesses that eliminate the most possibilities rather than guesses you think might be right.
How to play PIN Cracker
- Enter a guess
- Type or click the digits
- Submit
- Enter or the submit button
- Guess the hidden code.
- Feedback tells you how many digits are correct and how many are correctly placed.
- Use each result to narrow the possibilities.
- Crack the code within your allowed attempts.
PIN Cracker tips
- Open with a guess that tests as many different digits as possible.
- Change one digit at a time once you have partial information — it isolates what changed.
- Track which digits are ruled out; that's usually more useful than which are in.
- Position feedback matters more than count feedback late in a puzzle.
PIN Cracker — questions
How does the feedback work?
After each guess you're told how many digits are correct and how many of those are also in the right position — enough to deduce the code without ever being told it.
What's a good opening guess?
One that uses as many different digits as possible. The first guess is worth more as an information-gathering move than as an attempt to be right.
Does it work on a phone?
Yes — tap the digits. Nothing to install.
