KenKen is a math grid puzzle. Fill each row and column with digits 1 to N (where N is the grid size) so they don't repeat, and so each outlined cage matches its target using the given operation.

Do all puzzles have a unique solution?

Yes — every puzzle is generated with one valid solution reachable by pure logic and arithmetic.

What grid sizes and operations can I choose?

4×4, 5×5, and 6×6 grids. Toggle +, −, ×, and ÷ operations independently. Up to 100 pages, 1/2/4 per page.

Can I create a full puzzle book?

Yes — generate several puzzles, mix difficulties, and download a print-ready PDF with a full answer key.

Are the puzzles suitable for kids?

Yes — start with 4×4 grids and Easy difficulty. KenKen builds fluency with all four operations.

Does it work on mobile, iPad, and Chromebook?

Yes. The KenKen maker runs in your browser — no app required.

Do you store my puzzles?

No. Everything is generated in your browser session. We don't store, sell, or share your data.

Is this worksheet maker really free to use?

Yes — start without a credit card. Manual mode is always free to use and does not spend AI word credits. On the free plan you get 5,000 lifetime AI words (one trial per network), up to 10 PDF downloads per day, and a subtle eduzuma.com watermark on exports. Basic, Pro, and School plans remove the watermark, lift daily limits, and include a commercial resale license.

Do my PDF downloads have a watermark?

Free-plan and guest PDFs include a small eduzuma.com footer watermark. Paid plans (Basic, Pro, School) deliver 100% watermark-free PDFs — the upgrade most teachers and KDP publishers choose.

Is there a daily download limit?

Free and guest users can download up to 10 PDFs per day (tracked in the app). Paid plans include unlimited daily downloads.

Can I sell worksheets or puzzle books commercially?

Classroom and personal use are included on the free plan. Selling on Teachers Pay Teachers, Amazon KDP, Etsy, or similar requires Basic, Pro, or School — each includes a royalty-free commercial license and watermark-free PDFs.

Can I download multi-page worksheet packs on the free plan?

The free plan exports one page per generation. Basic supports up to 5 pages per click; Pro and School support unlimited multi-page packs — ideal for workbook sets, puzzle books, and full classroom packets.
