Wordfind is a simple javascript library for generating (hopefully fun) word find (also known as word search) puzzles.
Just give it a set of words and a few milliseconds later it will spit out a puzzle containing those words.
The core wordfind.js library contains no dependencies and will work both in the browser and in node.js.
The repository also includes a fully functional word find game (aptly called wordfindgame.js) as an example.
The game has a dependency on jQuery.
This is a fork of https://github.com/bunkat/wordfind allowing to specify the filling letters you want, letting some words be ommited and making the generator to retry with a bigger grid if none was found initially.
Check out the sample game at http://Lucas-C.github.io/wordfind/.
