Cipherlock - Crack the Code

Cipherlock is a cryptogram puzzle: every letter in a hidden phrase has been swapped for another letter, consistently, across the entire puzzle. Your job is to figure out which real letter each cipher letter stands for - and once you crack the whole alphabet, the phrase reads itself.

A few tiles are given to you at the start as freebies - your foothold into the puzzle. From there it's classic code-breaking: short words are your best early targets, repeated letters inside a word are a real clue, and the frequency counter at the bottom shows you exactly how often each cipher letter appears, the same way real cryptanalysts look for patterns. Assign a letter to one cipher tile and it fills in everywhere that letter appears - the moment your mapping is fully correct, the puzzle unlocks itself.

Every single puzzle in Cipherlock is checked by a solver before it ships. Given only the starting freebies, there is exactly one letter mapping that turns every ciphered word into a real word - never an alternate answer, never a lucky guess that happens to also work. If you solve it, you solved it for real.

WHAT'S INSIDE

- 56 handcrafted cryptograms across three difficulty tiers: Easy, Medium, and Hard
- Difficulty is measured by how many letters you actually have to deduce - from a handful up to nearly the full alphabet
- Natural, readable phrases - no obscure words, no proper nouns, just everyday vocabulary
- A frequency panel that turns letter-counting into a genuine solving tool, not busywork
- A simple tap-to-select, tap-to-assign interface built for quick sessions or long ones
- Instant conflict handling - reassigning a letter moves it, it never creates a duplicate
- Progress and stars saved automatically so you can pick up any puzzle later
- No timers, no penalties - just the cipher and your reasoning

WHO IT'S FOR

If you've ever solved a newspaper cryptogram, or you like the "aha" of Wordle crossed with the patient logic of a real code-breaking puzzle, Cipherlock is built for exactly that feeling. It rewards pattern recognition and deduction over speed, so it's just as good for a quiet ten-minute session as it is for chipping away at a Hard puzzle over a whole afternoon.
