Puzzle Generation
Guaranteed Uniqueness
Every Sudoku is permanently retired from our library once exported, ensuring no two publishers ever receive the same puzzle boards. Word Searches are dynamically generated with procedural matrix placements and random filler entropy, plus full support for custom vocabulary.
Grid Sizes
Choose from Classic 9x9, or branch out with 4x4 and 6x6 (perfect for Kids Mode) and 16x16 for hardcore experts.
Difficulty Levels
Seven levels: Easy, Medium, Hard and Master, plus Insane, Nightmare and Inferno for experts (the hardest levels cost 2–3 credits per puzzle).
Mixed Difficulties
Include multiple difficulty levels within a single book to provide a progressive challenge for your readers.
Maze Books
Maze Styles
Classic depth-first mazes with long winding corridors, evenly branched Kruskal mazes and dead-end-rich Prim mazes.
Shapes
Classic rectangles, circular mazes (rings around a center finish) and heart, star, Christmas tree, house, diamond and egg silhouettes.
Size & Difficulty
Rectangular grids from 5x5 to 100x100 cells with Easy, Medium, Hard and Expert presets. The configurator shows the printed corridor width and warns when it gets too narrow.
Loops & Start/Finish
Add loops for several possible routes, choose corner-to-corner, top-to-bottom or left-to-right openings, and pick text, arrow or icon markers.
Book Codes
Every maze book has a book code. The same code always prints the same mazes, every book of a series gets new ones, and the solution pages show the shortest path.
Word Scramble Books
Word Sources
Curated themes (900+ topics) or your own CSV list: Title,Word,Hint,Secret — rows with the same title become one puzzle.
Lengths & Rules
Choose the shortest and longest word and words per puzzle. Scrambles never repeat the original word or spell another real word unless you allow anagrams; Easy keeps the first letter.
Boxes, Clues & Secret Word
Print letter boxes or writing lines, clues under each word, and a secret word hidden in highlighted boxes.
Book Codes
Every word scramble book has a book code: the same code always prints the same puzzles, and every book of a series gets new ones.
Missing Vowels Books
Word Sources
Curated themes (900+ topics) or your own CSV list: Title,Word,Hint — rows with the same title become one puzzle. Words without a vowel to remove, with too few letters left or outside your lengths are listed with the reason.
Print Styles
Gaps (G_RD_N, a box for every missing vowel) or consonants only (GRDN) with one box per letter or a writing line. Presets go from Easy (first letter and vowel bank) to Expert; Y can count as a vowel.
One Right Answer
Easy, Medium, Kids and Large Print puzzles skip words whose gaps also fit another word (C_T = CAT, COT, CUT), checked against the theme dictionary and your own words. No puzzle prints the same gaps twice.
Clues & Editions
Print the missing vowels next to each word and your clues under it; answer keys highlight the restored vowels. Kids books use 3–6 letter words, Senior books large boxes. 1 puzzle (up to 25 words) = 1 credit, on every plan.
Cryptogram Books
Text Sources
Curated themes as word lists (900+ topics) or your own texts: one per line, or a CSV with Title,Text,Author. Texts need 25–250 letters; use your own words or public-domain quotes.
Ciphers
Aristocrat (word breaks kept), Patristocrat (groups of five) and shift codes, printed as cipher letters or number codes 1–26, with a random or keyword alphabet.
Exactly One Solution
A solver checks every cryptogram against a dictionary and reveals extra letters until only one reading is left. The Book Check shows the result and every text line that cannot be used.
Hints & Editions
Choose the revealed letters, print the author or theme as a clue and add an A–Z key strip. Kids books use shift codes with the key shown; Senior books use large print, one puzzle per page.
Wordoku Books
Letters & Hidden Word
Every wordoku uses the different letters of one word instead of numbers (9 letters for 9×9, 6 for 6×6, 4 for 4×4), and one row of the solution spells that word.
Word Sources
A built-in kid-safe word list, or your own words — one per line, up to 200. Words with the wrong length or a repeated letter are listed with the reason; your words are used in your order.
Difficulty = Sudoku
Every wordoku is a sudoku of our puzzle bank with letters instead of numbers: the same 7 levels from Easy to Inferno, the same credits per level, exactly one solution and never used in another book.
Hints & Editions
Print the letter bank (A–Z, never the word itself), "one row spells a hidden word" or the row number. Answer keys highlight the word row in your color. Kids books use 4×4 and 6×6 grids; Senior books use large print 9×9.
