Vault Cracker: Daily Code

A secret code is sealed in the vault every day. Everyone gets the same one. You get six guesses to crack it. VAULT CRACKER is a Mastermind-style deduction puzzle: four pegs, six colors, no repeats of information given away. After every guess you're told how many pegs were the right color in the right spot, and how many were the right color in the wrong spot — but never which peg is which. You have to reason your way to the answer through pure elimination, guess by guess. One code a day. One run at it. Miss a day or run out of guesses and your streak resets — so once you start, you'll want to keep coming back. HOW IT WORKS • A new 4-peg code is sealed in the vault every day, the same one for every player worldwide. • Six guesses to crack it. Tap colors to build a guess, lock it in, and read the feedback. • Track a real streak — it only survives if you crack the code every single day. • Share your result the moment you're done: a spoiler-free grid that shows how you did without ever revealing the code, or which color went where. • Stuck? Use your hint to get a mathematically optimal next guess. • Want more than one puzzle a day? Switch to Practice for unlimited random codes with nothing on the line. WHY IT'S DIFFERENT Most daily puzzle games are word games. Vault Cracker isn't — it's a genuine logic puzzle where every guess narrows down the possibilities, and the satisfaction comes from deduction, not vocabulary. If you've ever played the classic board game Mastermind, this is that same "aha" moment, reduced to one perfect daily puzzle. Built for players who like their brain teasers sharp: no timers, no pressure, just a clean deduction problem and six chances to solve it. Vault Cracker is free to play, supported by ads. A single one-time purchase removes them for good.
