Three ways to get a puzzle
Built around how you actually solve
A bundled archive of public-domain crosswords gets you solving right
away. Import your own .puz and .ipuz files if
you already have puzzles you like. Or use the built-in generator to
create a new one on demand.
Privacy by default
Nothing leaves your device to solve a puzzle
Solving works fully offline. There are no accounts, no sign-in, and no cloud sync — your puzzles and progress stay on your device.
The generator
Clues are written by AI. The grid never is.
Generated puzzles use AI-written clues. The grid fill itself always comes from a vetted word list, never from a language model — only the clues are AI-generated, and every clue is written for a fill that's already fixed.
