About
Calm puzzles, made carefully
Quill Delights is a small publisher based in Scotland. We make puzzle books, large print word search, sudoku, killer sudoku, jigsaw sudoku and more, for people who like to solve on paper, or on a tablet with a stylus, and for the people who buy for them.
Puzzles made to be solved
Our software makes every puzzle, and a computer checks each one before it goes in a book. A sudoku has exactly one solution. A word search hides each word exactly once. If a puzzle fails a check, it does not go in.
Levels set by the solving, not the clues
A sudoku is solved the way a person would solve it, step by step. Easy needs only the simplest steps. Medium needs a new method. Hard needs an advanced one. The level is the hardest step a puzzle asks for, so a Hard puzzle really is harder, and an Easy one really is gentle.
Print that is easy on the eyes
In our large print books every word and number is at least 16 point, including the instructions, the page numbers and the answers. We set the type in the same families as this site, chosen to be easy to read.
Based in Scotland, sold around the world
We design and check every book in Scotland. Paperbacks are printed on demand by Amazon and sent to readers in the UK, the US and many other countries. The PDF downloads can be printed at home or used on a tablet.
How the books are made
The puzzle grids are made by our own code. Some word lists and themes are drafted with the help of AI and then checked by us. The covers and pages are laid out by our own software.
