About Pin Cracker
Pin Cracker asks you to guess a secret code made of numbers. You enter a guess and the game colors each digit. Those colors tell you which digits to keep testing.
A yellow color means the digit lives in the code but sits in the wrong place. A green color shows that the digit matches and sits in the correct slot. This hint scheme makes it clear which numbers belong and where they fit.
Green digits stay locked in place from that point forward. Yellow digits need new positions until they turn green. This simple cycle helps you crack the code in fewer moves.
