Printable Cryptarithm Puzzles and Worksheets

Print the puzzle you are playing

Every puzzle has a printer button at the top right, beside the timer and the share button (circled in red below). It prints that puzzle alone on an A4 page: the arithmetic with its empty squares, A = ___ answer lines for letter puzzles, the puzzle type, operation and difficulty at the top, and cryptarithm.com with a QR code that opens the same puzzle online. Menus, buttons and the keypad are left out.

A puzzle you have not started prints straight away. Once you have entered digits, choose Print blank puzzle or Print with my entries.

How the worksheet maker works

Choose Digits or Letters, one or more operations, a difficulty, how many puzzles go on a page (2 to 12) and how many pages to print (1 to 5). Generate worksheet creates new puzzles on our server, each checked for a unique solution, and shows every page as it will print. Each page has lines for a name, the date and the class, numbered puzzles with room to work, and cryptarithm.com with the page number at the bottom.

A worksheet holds up to 60 puzzles. Short puzzles fit twelve to a page; long division and multiplication with partial products need more room, so the maker suggests fewer per page for them. Generating again gives a different set.

Quick-start buttons above the form fill it in for you: a short digit warm-up, a step up with letters, a challenge with multiplication and division, and a small Kakuro starter. They describe difficulty and use, not a school grade; change anything afterwards.

Answers

A worksheet can end with an answer key. With Answer key on the last page ticked (the default), the solved puzzles follow the worksheet on the last page or pages, under the heading Answer Key, numbered to match and set small and compact, with the same cryptarithm.com footer and page numbers. Untick it to print only the puzzles. For Kakuro the key shows each grid filled in; All Ten has no key, because the same four numbers can make a target in many ways.

The answers come from our server together with the worksheet you generate here, and only for those puzzles. Puzzles you play in the game, the Daily Challenge and the Check button never reveal them. To check a puzzle printed from the game, scan its QR code and use Check.

Printing tips

In the print dialog, choose A4 and portrait, and keep the default margins. If your printer uses Letter paper, choose Fit to page. Turn off the browser’s own headers and footers if they appear. Pages are black on white with no shaded backgrounds, so they print clearly in black and white and use little ink.

A clean image for slides

To put a puzzle into your own document or slides, open Share and choose Download puzzle image (PNG). The image has the arithmetic and any letter answer lines on a white background, with no branding, QR code, timer or player progress.

Copy puzzle link in the same panel saves a link that recreates the exact puzzle later, without anyone’s entries.

Share to Google Classroom

The Share to Classroom button on this page, and in the Share panel of Cryptarithm, All Ten and Kakuro, opens Google Classroom’s own share page in a new window with a link to this page or puzzle, so you can post it as an assignment, a question or material. Students who open the link play in their browser; no account is needed. We send nothing to Google when you press the button, and the Classroom page asks you to sign in with your own Google account.
