A quote with every letter swapped for another, consistently. The solver works out the substitution using letter frequency and word shapes.
Encode famous quotes, riddles or your own secret messages into classic letter-substitution cryptograms, with optional hint letters and a full solution. Popular for KDP cryptogram quote books, escape-room style classroom games, and puzzle variety packs. Cryptograms can also be solved on screen, where one guess fills every occurrence of that letter at once.
40 to 90 characters. Under about 30, no letter appears often enough to reveal itself by frequency and there is nothing to cross-check.
A name follows no spelling pattern the solver can use, so it turns from a clue into a dead zone — usually cracked last, which is backwards.
Two is right for most audiences. Which letters matters more than how many: revealing E or T opens the puzzle up, revealing Q helps nobody.
It is the best of our puzzles on a phone — there is nothing to drag, you tap a coded letter and choose what it stands for.
Export as a US Letter PDF for print, or as PNG/JPG for image-based layouts. Amazon KDP supports multiple trim sizes, including 8.5 × 11 inches for applicable books; build the final interior to the trim size you selected and keep raster artwork at 300 DPI. There is also a grid-only export if you are dropping the puzzle into your own page layout.
This one can also be played in the browser: press Play above to solve it on screen, or Share to send a link that opens playable for whoever receives it — no account and no app at their end.
