Pick a level and how many, then print. Answer pages included.
How to print
Choose the level, puzzles per page and number of pages, then press Print. You can also save as PDF from the print dialog.
New puzzles are created every time. Each one is checked by the program to have exactly one solution.
For kids or older players, one large puzzle per page is easiest to read.
Ready-to-print PDFs (with answers)
Each PDF has 10 puzzles (US Letter, 2 per page, 7 pages). Puzzles are on pages 1–5 and answers on pages 6–7, so print pages 1–5 to hand out without answers. On A4 paper, choose "Fit to page".
Print and photocopy them freely at home, in schools, after-school programs, senior living communities, nursing homes, senior centers, hospitals and libraries. No permission needed.
Use them in class, as homework or in activity programs, and combine them with other worksheets into a packet if you like.
Sharing within your school or facility is fine, including your class app or a staff-only drive.
Using them in programs or classes that charge a fee is fine.
Please
If you post on a page anyone can download from, please link to this page instead of uploading the PDFs.
Keep the puzuru.com line at the bottom of each page. If you cut out a puzzle for a newsletter, add "Source: puzuru.com".
Please don't sell the printouts themselves.
