How it works
A bounded solution counter stops after finding two solutions. The tool does not label puzzles Easy, Medium, or Hard because clue count alone does not prove human solving difficulty.
Privacy and limits
Your entries and generated puzzle stay in this browser tab. This tool has no account, upload, cloud save, or sharing feature. Closing or resetting the page discards the current puzzle. Printing is handled by your browser; check paper size and scale before using printed copies.
