Lockwise: Crack the Code

Every lock has a secret code. Every clue is an earlier attempt at it. Read the clues, reason it out – and hear the safe click open.

Lockwise is a calm, clever code-breaking puzzle. Each level gives you a handful of past guesses and how close they came:
● a right digit in the right place
○ a right digit in the wrong place
✕ none of its digits are in the code

From that alone you work out the one code that fits. No timers pushing you, no luck, no guessing – every puzzle has exactly one solution, and you can always reach it by logic.

HOW YOU PLAY
• Turn the clues into facts on the lock rings: cross digits out, tick the ones you are sure of.
• Auto-exclusion does the bookkeeping for you, so you can focus on the thinking.
• Make notes on the clues themselves and grey out the ones you have used up.
• Undo and redo any move.

HINTS THAT TEACH
Stuck? The hint first shows you where to look, then explains why, step by step – and only fills it in if you ask. You learn the trick instead of just getting the answer.

A NEW LOCK EVERY DAY
A free daily puzzle for everyone, easy on Monday and toughest on Sunday. Keep your streak going, catch up on the last week, and get an optional reminder at 7 pm.
