Free, no usage limit.
sudokuaddedCreates a sudoku with exactly one solution. Returns puzzle (0 = empty cell) and solution. Sizes 4, 6, 9 (default), 12 and 16; difficulty 1 easy (most clues) to 4 expert. Free, no usage limit. The same seed gives the same sudoku.
crosswordaddedLays out a crossword from words with clues. Returns two matrices of the same size: puzzle (the game position: "-" is a blank cell, a word's number is on its first cell, "0" marks the other cells where a letter goes, and "a/d" such as "3/4" appears when an across word and a down word start in the same cell) and solution (the same matrix with the correct letters, one grapheme per cell). placements lists every word with its number, clue, direction (across/down) and start cell; unplaced lists words that did not fit. Offer more words than you need: the engine keeps the best layout it finds. Native letters (Ñ, Ç, ẞ…) stay one cell each. Free, no usage limit. The same seed gives the same crossword.
list_stylesaddedThe Unicode text styles stylize_text offers, with the id to pass, an English name and a category (bold-italic, sans, script, gothic, mono, enclosed, decoration, other).
stylize_textaddedTurns text into Unicode styles for social media bios and posts: bold, italic, script, fraktur, monospace, circled, squared, fullwidth, small caps, strikethrough, underline and more (22 styles). Accents are kept: an accented letter becomes its styled base letter plus the combining accent (ñ, ç, ü, ß work). Not every style can draw every character: letters such as ß, Æ, Œ, Ø or non-Latin scripts stay plain, and accented letters rely on a combining mark that some fonts draw badly. Those characters are listed in notNative for each style, and parts with missing: true mark them, so you can warn the user or show an empty box. Set classic to strip accents first. Pass one style id, several, or none for all styles (see list_styles). Runs locally and has no usage limit.
generate_word_searchchangeddescriptionCreate a word-search puzzle (sopa de letras) from a list of words. Keeps native letters (Ñ, Ç, Ã, Ä, ẞ, È…) as one cell each. Returns the grid, where every word is hidden, and any words that did not fit. Empty cells are marked "-": call fill_word_search with the grid to complete it with random letters. The same seed always gives the same puzzle.

crossword | Lays out a crossword from words with clues. Returns two matrices of the same size: puzzle (the game position: "-" is a blank cell, a word's number is on its first cell, "0" marks the other cells where a letter goes, and "a/d" such as "3/4" appears when an across word and a down word start in the same cell) and solution (the same matrix with the correct letters, one grapheme per cell). placements lists every word with its number, clue, direction (across/down) and start cell; unplaced lists words that did not fit. Offer more words than you need: the engine keeps the best layout it finds. Native letters (Ñ, Ç, ẞ…) stay one cell each. Free, no usage limit. The same seed gives the same crossword. |
fill_word_search | Completes a word search: takes the grid from generate_word_search (empty cells are "-") and fills them with random letters in the chosen language, with accents on or off. Letters follow how common they are in that language. Pass the puzzle's words so the filler never creates an extra copy of one. |
