The NASPA Zyzzyva FAQ, as with everything Zyzzyva-related, was originally written by Michael Thelen and then transferred to NASPA in 2014.
Michael Thelen writes: I wanted to pick a fun word that was somewhat unique. I knew zyzzyva was one of the most improbable words to be played in a SCRABBLE game, and I liked the sound of it. Later on, after I had picked the name, I realized that since zyzzyva was also the last word in alphabetical order (it has since been replaced by zzz), I could call Zyzzyva the last word in word study. I wish I could say I was smart enough to come up with that slogan from the start.
Michael Thelen writes: I created Zyzzyva because I wanted a program for studying SCRABBLE words. There are several programs available, but all of them either lack features I wanted or do not run on Linux. I therefore took it upon myself to create the program I wanted, and Zyzzyva is the result.
NASPA adds: We appreciate Michael’s efforts in developing Zyzzyva and are committed to continuing to make it freely available to the SCRABBLE community. For licensing reasons, however, and the need to support proprietary word lists, Zyzzyva is now closed-source.
Michael Thelen originally wrote: That is so nice of you! I'm always very happy to receive donations of any amount.

NASPA Zyzzyva is currently available for the Windows, macOS, and Linux platforms.
Later in 2021, the new NASPA Zyzzyva Mobile app will be made available for iOS and Android devices. Please see that page for information about the mobile version.
When you install a new version of NASPA Zyzzyva, it does not change the list of lexicons to include any newly added word lists.
Follow these instructions to make a word list available in NASPA Zyzzyva:
If the word list is not included in NASPA Zyzzyva, you may be able to load a text file version of the word list as a custom lexicon.
It depends on the word list, but you should in general ask the copyright holder for permission to use an electronic copy of the word list.
If you need help formatting it for use with Zyzzyva, please feel free to contact us.
There is no print functionality built into Zyzzyva. You can, however, right-click (Control-click on a Mac) on any word list (e.g., Search results) and save it in plain text format. Then manipulate the list and print it from a text editor program, like Notepad on Windows.
After you load a word list, you must build the database for that word list. Go to Tools -> Rebuild Database and choose the new word list or all word lists.
Also, make sure that the Show Definitions option is checked in Word Table Preferences under the Edit menu.
Note that NASPA Zyzzyva's license to Collins word lists does not include definitions.
Those marks denote inner hooks - they mean that either the first or last letter of the word can be dropped to form another valid word, depending on where the mark appears. If the mark appears at the beginning of the word, then the first letter can be dropped. If the mark appears at the end of the word, then the last letter can be dropped.
You can choose whether to display a hyphen or a bullet character to denote inner hooks in Word Table Preferences under the Edit menu.
Zyzzyva only marks all responses as missed if you actually entered all the correct responses, but also provided an incorrect response. The reason for marking all responses as missed is because (currently) Zyzzyva has no other way of marking the question as missed without marking at least one response as missed. So instead of picking a random response to mark as missed, it marks them all.
This only happens if you have the 'Mark question as missed after an incorrect response' setting activated, but not 'End question after an incorrect response'. Technically, it could also happen if you have the 'End question after an incorrect response' setting activated, but not 'End question after all correct responses', and the incorrect response is the last one you give.
The basic idea is that you must first tell Zyzzyva which words you'd like it to keep track of. You generally do this by performing a search, then right-clicking the search results, and choosing Add to Cardbox. Then Zyzzyva keeps track of those words and automatically quizzes you on the ones it thinks you need to see each day. When you miss a word frequently, Zyzzyva will show it to you more often.

Cardboxes are separate for each word list. You can, however, import quiz statistics and cardbox data from one word list to another.
If the word list from which you are importing data is subject to licensing restrictions, you will need to have a valid license installed. Choose Tools > Manage Licenses to check the status of your license.
Do the following:
All your cardbox data will be removed from the system, but your historical quiz data will be retained.
You can transfer all your data to a new computer by copying your data directory. You can find out where your Zyzzyva data directory is by opening the Preferences window in Zyzzyva and looking at the Data Directory setting. Make a copy of this directory, and move it to wherever you like, on the new computer. Then, after you install Zyzzyva on the new computer, open the Preferences window and change the Data Directory setting to point to wherever you put your data directory from the original computer.
The transfer should work regardless of the operating systems used on the two computers. For example, you should be able to transfer your data directory from a Windows computer to a Mac, or vice versa.
Here are general instructions for changing the location of your data directory. You may find it useful to move the data directory to facilitate the synchronization of data between Zyzzyva on multiple devices - for example, through Dropbox.
Be sure to follow these directions closely because manually manipulating the Zyzzyva data directory can be potentially dangerous to your data if you're not careful. You should probably read the full instructions before taking any action so you're familiar with what steps are required.
Note: In Zyzzyva versions before Release 2.1.0, the default data directory was a hidden folder named .Zyzzyva. You will have to enable the viewing of hidden folders to move that data directory.
Absolutely. This may be a good option for anyone wanting to use Zyzzyva on multiple computers without having to copy data directories back and forth. Simply copy your data directory onto the USB drive (using the process described to transfer Zyzzyva data from one computer to another). Then open the Preferences window and change the Data Directory setting to point to the data directory on the USB drive.
There isn't a handy formula, but it's basically a straight calculation of the number of possible combinations to get a particular set of letters from a full bag, including blanks. Separate combination values are calculated for drawing zero, one, or two blanks, and then the numbers of combinations are added together to get the total number of ways of drawing a word.
Yep, it really is correct. The calculation of probability is notorious for violating human intuition. One useful guideline to remember is that doubled or tripled letters make a particular letter combination much more improbable than you might think. That's because the number of ways to draw two identical letters out of the bag is generally much lower than the number of ways to draw two different letters out of the bag.
Consider BAILERS versus BELIERS. BAILERS is a fair amount more probable than BELIERS because of the doubled Es in BELIERS. However, it seems intuitive to say, "If BEILRS has been drawn from a full bag, then there are 9 As and 11 Es in the remaining pool. The E is the more likely draw, which means BELIERS should be more probable than BAILERS."
While it is true that drawing a single E is more likely than drawing a single A, the math for calculating the probability of a word is more complicated than that. You can't just start calculating with the assumption that BEILRS has been drawn; those letters themselves factor into the calculation, and they are not independent events. In this case, we can reduce the difference between BAILERS and BELIERS to the difference between drawing AE or EE when drawing two tiles from the bag.
If you draw two tiles out of a full bag, the probability of drawing two Es is much lower than the probability of drawing an A and an E. That is because there are 9 x 12 = 108 ways to draw an A and an E if you draw two tiles. But there are only (12 x 11) / 2 = 66 ways to draw two Es if you draw two tiles. This number of combinations is called "12 choose 2", and is explained in more detail in this Wikipedia article about combinations.
To reduce this to a simple example where it's easy to enumerate all the possibilities, consider a 4-tile bag containing only AAEE. I'll label the tiles A1, A2, E1, E2 for convenience. There are 6 possible ways to draw two unordered tiles:
A1 A2 = AA A1 E1 = AE A1 E2 = AE A2 E1 = AE A2 E2 = AE E1 E2 = EE
As you can see, AE is drawn 4/6 times, while AA is drawn only 1/6, and EE is drawn only 1/6 as well. Even though A and E are equally likely to be drawn if you are only drawing one tile, if you're drawing two tiles, it is much more likely to draw one of each than to draw duplicates.
As another example, consider a bag where E is more likely than A, as is the case in the full SCRABBLE bag. Consider a 6-tile bag containing AAEEEE, with tiles labeled A1, A2, E1, E2, E3, E4. There are 15 possible ways to draw two unordered tiles:
A1 A2 = AA A1 E1 = AE A1 E2 = AE A1 E3 = AE A1 E4 = AE A2 E1 = AE A2 E2 = AE A2 E3 = AE A2 E4 = AE E1 E2 = EE E1 E3 = EE E1 E4 = EE E2 E3 = EE E2 E4 = EE E3 E4 = EE
AA occurs 1/15 times, AE occurs 8/15 times, EE occurs 6/15 times. Even though E is twice as likely as A, AE is still more likely than EE! This is the same basic principle that also causes words with duplicate letters to be drawn with lower probability from a full SCRABBLE bag.
Complicating the math even further is the fact that Zyzzyva calculates probabilities using a full 100-tile bag including two blanks. That may account for differences (usually minor) with other probabilities you may have seen calculated elsewhere, many of which use a 98-tile bag with no blanks.
Access to OTCWL2014 and OTCWL2016 is restricted to current NASPA members by Hasbro. Members needed to claim a license for each device where Zyzzyva is installed.
The word lists currently shipping with NASPA Zyzzyva do not require a license.
You will only need a license if you need to upgrade quiz statistics and cardbox data from OTCWL2014, OTCWL2016, or CSW15 to another word list.
Make sure that you are connected to the Internet. If so, Norton Antivirus or a similar utility may be blocking Zyzzyva from accessing the Internet. To resolve the issue, you will need to turn off the firewall within Norton. Once you claim or activate your Zyzzyva license, you can turn the firewall back on.
NASPA word list licenses are valid for simultaneous use on at least ten different devices. If you need to use yours on more, please contact us at info@scrabbleplayers.org.
