LockCode is a daily code-cracking puzzle inspired by the classic Mastermind game. Each day features a new secret code to crack at three difficulty levels — Easy with 3 digits, Medium with 4 digits, and Hard with 5 digits. You are given clues that show test codes with feedback on how many digits are correct and in the right position, how many are correct but misplaced, and how many are not in the code at all. Use logical deduction to narrow down the possibilities and crack the code before running out of attempts. Every code uses unique digits with no repeats, and all players receive the same daily puzzles.
