'''Zyzzyva''' is a word study and word
adjudication [[software|program]] created by [[Michael Thelen]], purchased by NASPA in September 2014.
Zyzzyva is freely available and runs under Linux, Windows Vista, Windows XP,
Windows 2000, Windows 98, Windows ME, Mac OS X 10.3.9 or later (Panther),
Mac OS X 10.4 (Tiger), and Mac OS X 10.5 (Leopard).
There is a separate iOS app version of Zyzzyva, developed for the now dated iOS 6. Soon after our acquisition of Zyzzyva, we learned that its iOS app is not compatible with iOS 8. After we have released the next version of the desktop Zyzzyva app, we will work on an iOS 8-compatible version of the mobile Zyzzyva app, which we are hoping will be available early in 2015. We then intend to discontinue the Lite version of the mobile app to continue only with the full version, which will be repriced as a free app. Please watch for an announcement about the next version of Zyzzyva in January.
Zyzzyva has been used as at software self-lookup stations at many North American [[SCRABBLE]] [[tournaments]],
