Pick a difficulty and how many puzzles you want on the sheet, and you'll get a clean page ready to print — no ads, no app chrome, just grids. Answers print on a separate page after the puzzles, so you can hand out the puzzle side without giving anything away. Printing works the way it always has: open your browser's print dialog, and if you'd rather have a PDF than paper, "save as PDF" is built into every modern browser's print screen. Every printed puzzle is checked for exactly one solution first, the same as anything you'd solve on screen. Prefer to solve on screen instead? Easy, Medium, Hard, and Expert are all one click away.
