A puzzle book studio for Amazon KDP publishers
Wisdom Effect is a browser-based studio for print-ready puzzle books: the interior and the full paperback cover. We build the generators, the page editor and the KDP checks, and we write the guides on this site with the same tool.
What we make
Seven puzzle types, mixed books and three editions
Sudoku, Word Search, Mazes, Word Scrambles, Missing Vowels, Cryptograms and Wordoku, alone or as chapters of one mixed book, each in a Standard, Kids or Large Print edition, with answer keys and PDF, PNG or SVG export.
Our puzzles
How we make and check every puzzle
Checked before it is printed
Every sudoku, wordoku and cryptogram is checked by a solver to have exactly one solution, and missing vowels puzzles in Easy, Medium, Kids and Large Print skip words with two possible answers.
Never sold twice
Every sudoku and wordoku you export is retired from our puzzle bank, so no other publisher gets the same grid.
Reproducible books
Mazes, word scrambles, missing vowels and cryptograms are generated from a book code: the same code reprints the same book, and a series gets new puzzles.
KDP rules built in
The gutter follows the page count, the outside margins match KDP, interiors export at the exact trim size, and the cover gets its bleed and a spine sized to the page count and paper.
Our guides
How we write the blog
The guides and benchmarks are written by the Wisdom Effect Editorial Team, the people who build the generator.
Made with our own generator
The pages, screenshots and measurements in our guides come from books we make in Wisdom Effect, the same way you would.
Independent benchmarks
Benchmarks rate puzzles with outside tools, not with our own engine, and link the raw files so you can repeat every test.
