The following sources have been useful in the creation of the Chihuahua word puzzle.


Chihuahua uses its own word list, compiled with the use of many resources, in particular:


Chihuahua is designed to run without the need for Java or Flash plugins. (Although where Flash is available, it may be used to play sounds if the sound effects option is selected.) Chihuahua uses JavaScript and CSS. Perl and MySQL are used on the server. Communication with the server uses the jQuery implementation of Ajax.

Chihuahua uses Scott Schiller's SoundManager2, a JavaScript interface for playing sounds. Chihuahua also uses the JavaScript implementation of the MD5 hashing algorithm by "Paj" (Paul Johnston) and the YUI Compressor JavaScript compression tool.

Sounds and images

Some of the sound effects in the puzzle were purchased from the SoundRangers library.
