If you’re searching for a new mental challenge, this is the puzzle book for you! Offering sixty separate fill-in grids, this volume of crossword games calls for a special kind of cleverness. Rather than simply testing your memory like regular crosswords, fill-ins provide a list of answers and require you to determine where they fit into the grid.

Each numberless grid displays one word that is already filled-in, while blacking out the unusable squares. From there, you must fill in the remaining white squares with the words listed below. While most fill-in puzzles are 15 x 15 or smaller, this collection offers a variety of sizes, from 13 x 13 all the way up to a challenging 23 x 23!

Whether you’re looking for a productive way to spend your daily commute, preparing for a trip, or just in need of a good brain teaser, these fill-ins will keep you sharp-and entertained-for hours on end.

Once you’ve conquered Fill-In Puzzles, be sure to pick up Richard Emmons’s Diagramless Fill-Ins, which you can preview by testing your brain against the bonus word puzzle included at the end of this book!
