NASPA Zyzzyva is a word study and word adjudication program.

Supported Operating Systems

NASPA Zyzzyva is currently available on the Windows, macOS, and Linux operating systems.

A new “mini” version that will support tablets and smartphones, both Android and iOS, is under development. At this time, there is no date for the completion of this new version.

Current Version

Version 3.3.0 introduces the CSW21lexicon. It continues to include the NWL2020, NSWL2020, NWL2018, NSWL2018, CSW2019, and Volost lexica.

Word list availability may be restricted by licensors to current NASPA members.


Michael Thelen wrote the original version of what was then Zyzzyva, and maintained it for many years as it gained worldwide popularity. Zyzzyva has been used at software self-lookup stations at most North American SCRABBLE tournaments, including BAT, Oregon TILE, the Dallas Open, the National SCRABBLE Championship, National School SCRABBLE Championship, the Canadian National SCRABBLE Championship and the World SCRABBLE Championship.

In September 2014, NASPA bought all rights to Zyzzyva, and we have worked since then with our SCRABBLE partners to ensure licensed access to all the official word lists for our members.

Ross Brown has continued development of the desktop edition of what became NASPA Zyzzyva, with Michael Donegan initially taking over development of the iOS edition. Ross Brown is now creating a common code base for all NASPA Zyzzyva platforms.
