How to make a word search book that people actually finish

A word search book is not a pile of grids. It is a difficulty curve, a theme somebody searched for, and a page that an eighty-year-old can read across a kitchen table. Get those three right and the book sells for years.

The theme is the product

Almost everyone who makes a first puzzle book makes a general one, and almost every general one disappears. The grids inside every word search book are much the same; the only thing a buyer can tell apart on a search results page is the subject and the typography.

So choose a theme with a crowd already attached to it. Not "animals" but "birds of the British garden". Not "Bible" but "the parables, one per puzzle". Not "travel" but "the Camino de Santiago, town by town". A theme like that does three things at once: it narrows your competition, it gives you the word lists without inventing them, and it tells you exactly who to show the book to when it is published.

Grid size, word count and the difficulty curve

A word search is difficult in three separate ways, and you should move them one at a time rather than all at once.

• Grid size. More letters, more scanning. 10x10 for children, 15x15 for adults, 13x13 when the type has to be large.
• Directions. Left-to-right and downward only is gentle. Adding diagonals roughly doubles the search. Adding backwards words doubles it again. Eight directions is the hard end, not the default.
• Crossings. Words that share letters are far harder to spot than words sitting in clean space, because a found letter leads somewhere wrong. A good generator packs words so they cross; a lazy one scatters them.

Lay the book out as a ramp. The first ten puzzles should be forward and downward only, generous grid, no reversals. The middle forty add diagonals. The last twenty run all eight directions with heavy crossing. Say so on the contents page: solvers like knowing the book gets harder, and they blame themselves rather than you when puzzle sixty is hard.

One detail that separates a good book from a generated one: the filler letters. If the letters around the words are chosen at random from the whole alphabet, the hidden words stand out, because a word list full of E and R sits in a field of Q and Z. Drawing the filler from the same letter distribution as the words themselves makes the grid uniform and the puzzle honest.

Large print is a market, not a formatting option

The single largest audience for word search books is people over sixty-five, and the most common one-star review on a puzzle book is that the letters are too small. Large print is not a courtesy; it is the product.

A large-print edition means 14 to 16 point in the grid, a 13x13 maximum, one puzzle per page with the word list beneath it rather than beside it, and real white space at the margins so the book can be held open flat. It also means the word list is set in the same size as the grid. Publishing the same book twice, once standard and once large print, is the cheapest catalogue expansion in this category.

Page geometry, and why vectors matter here

Print is unforgiving about resolution. Amazon asks for images at 300 dots per inch or better and warns or rejects below it. An image generated by a model at, say, 832 by 1216 pixels is about 2.8 by 4.1 inches at 300 DPI: too small for a page, and enlarging it just spreads the same pixels further apart.

A puzzle page has no business being an image at all. It is lines, letters and boxes, which is exactly what vector drawing is for. A vector page has no resolution: it is a set of instructions that the printer renders at whatever precision the press can manage. Print it at 8.5 by 11 inches or at A3 and it is equally sharp. This is why Neubook draws every printable page rather than generating it.

The answer key

Put the solutions in the back, never opposite the puzzle. Four solved grids to a page at quarter size, each labelled with its puzzle number, keeps the section short. Readers will accept small answer grids; they will not accept no answers at all, and reviews say so.

Publishing and pricing

Two routes, and most people should take both.

• A paperback on Amazon. Print on demand, no stock, no postage. You are competing on cover and theme, so spend your effort there. Follow the paperback guidelines exactly; the formatting troubleshooting page explains every warning you are likely to see.
• A printable PDF on Etsy. Buyers print it themselves, which suits activity directors, teachers and carers buying for a group. Etsy charges a listing fee, a transaction fee and payment processing, currently 20 cents per listing and sale, 6.5 percent of the total, plus processing, so a five dollar download nets you a little over four.

Price the paperback where the category sits rather than where you would like it to. Undercutting by a dollar wins nothing; a better cover and a sharper theme win everything.
