Before you begin looking for a publisher, refine the idea for your puzzle so that you are able to state it simply in one sentence. For example, “This puzzle book will feature cryptograms all with the theme of outer space,” or “Here is an all new puzzle form, each is a combination of brainteasers and word searches.”
Create at least six sample puzzles that clearly demonstrate your idea. Find some puzzle lovers and ask them to try out your puzzles and make comments. If necessary, refine your idea or your puzzles in light of the comments or suggestions you receive.
You will want to know which publishers produce puzzle books similar to your idea. Start by visiting both your local library and a bookstore to study the puzzle books and make a list of publishers’ names. Make sure you stick to puzzle books published in the last few years. You can also search an online bookstore in the same way; however, you won’t have the opportunity to study the contents.
By using a copy of the Writer’s Market (see Resources below) or searching for each publisher online, find out which ones are accepting unsolicited manuscripts.
Following the publisher’s guidelines, prepare your submission. It should include a cover letter stating the idea for your puzzle book and any experience you might have in writing puzzles (for a local newspaper perhaps). You should also state any other writing or related experience you have. The cover letter should include all your contact information (street address, e-mail address, phone numbers) and thank the publisher for looking at your submission.
Include your six sample puzzles. These should be neatly typed without the answers; the answers should appear below the puzzle.
Some publishers accept electronic submissions; others want hard copies; take careful note of this. If it is an electronic submission, your cover letter will go in the e-mail, with your puzzles as an attachment. Try to send the submission to the attention of a particular editor.
