Fill-in puzzle books for Amazon KDP & Etsy

A crossword without clues. The solver gets the grid and a list of words sorted by length and has to fit every word into the squares where it crosses the others. Fill-ins are also called kriss-kross, word fit or criss-cross puzzles.

Before a fill-in goes into your book, a solver tries every way the listed words fit the grid. If two fillings work — for example two 5-letter words that could swap — another word is printed in the grid and the check runs again. The book check in the configurator shows the result for the first puzzles of your book.

A crossword gives clues and the solver has to find the words; a fill-in gives the words and the solver has to find where they go. It needs no general knowledge, which makes fill-ins a favorite for relaxing puzzle books, seniors and kids learning to spell.

One word printed in the grid to begin with, so the solver knows where to start. Expert books can leave it out; a grid that would otherwise have two solutions still gets the word it needs.
