How the tool works
Choose a difficulty, generate a puzzle, and solve it right on the page with instant answer checking.
Print-first workflow
Print output is now stripped down for teachers: no header, no hero image, no cards, and no controls. The printed page only includes the worksheet title, name line, difficulty, puzzle grid, and the answer key only when you intentionally reveal it.
