How to play
One case a day. Crack the hidden 4-letter word, then shift it into the target — one letter at a time. No timer, no guess limit.
1 Lock — deduce the word
Guess any real 4-letter word. Each guess returns two clues:
- Exact — right letter, right spot
- Misplaced — right letter, wrong spot
Say the hidden word is
NEST and you guess
SENT:
SENT
2 exact (E, T) · 2 misplaced (S, N)
Keep guessing until all four are
exact.
2 Shift — reach the target
Turn your cracked word into the day's target, changing one letter per rung — and every rung must be a real word.
From
NEST to target
MUST:
NEST → BEST → BUST → MUST
Any path works — there's no step limit.
